1 Woe to Ariel, to Ariel, the city where David dwelt! add ye year to year; let them kill sacrifices. 2 Yet I will distress Ariel, and there shall be heaviness and sorrow: and it shall be unto me as Ariel. 3 And I will camp against thee round about, and will lay siege against thee with a mount, and I will raise forts against thee. 4 And thou shalt be brought down, and shalt speak out of the ground, and thy speech shall be low out of the dust, and thy voice shall be, as of one that hath a familiar spirit, out of the ground, and thy speech shall whisper out of the dust. 5 Moreover the multitude of thy strangers shall be like small dust, and the multitude of the terrible ones shall be as chaff that passeth away: yea, it shall be at an instant suddenly. 6 Thou shalt be visited of the LORD of hosts with thunder, and with earthquake, and great noise, with storm and tempest, and the flame of devouring fire. 7 And the multitude of all the nations that fight against Ariel, even all that fight against her and her munition, and that distress her, shall be as a dream of a night vision. 8 It shall even be as when an hungry man dreameth, and, behold, he eateth; but he awaketh, and his soul is empty: or as when a thirsty man dreameth, and, behold, he drinketh; but he awaketh, and, behold, he is faint, and his soul hath appetite: so shall the multitude of all the nations be, that fight against mount Zion. 9 Stay yourselves, and wonder; cry ye out, and cry: they are drunken, but not with wine; they stagger, but not with strong drink. 10 For the LORD hath poured out upon you the spirit of deep sleep, and hath closed your eyes: the prophets and your rulers, the seers hath he covered. 11 And the vision of all is become unto you as the words of a book that is sealed, which men deliver to one that is learned, saying, Read this, I pray thee: and he saith, I cannot; for it is sealed: 12 And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned. 13 Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men: 14 Therefore, behold, I will proceed to do a marvellous work among this people, even a marvellous work and a wonder: for the wisdom of their wise men shall perish, and the understanding of their prudent men shall be hid. 15 Woe unto them that seek deep to hide their counsel from the LORD, and their works are in the dark, and they say, Who seeth us? and who knoweth us? 16 Surely your turning of things upside down shall be esteemed as the potter's clay: for shall the work say of him that made it, He made me not? or shall the thing framed say of him that framed it, He had no understanding? 17 Is it not yet a very little while, and Lebanon shall be turned into a fruitful field, and the fruitful field shall be esteemed as a forest? 18 And in that day shall the deaf hear the words of the book, and the eyes of the blind shall see out of obscurity, and out of darkness. 19 The meek also shall increase their joy in the LORD, and the poor among men shall rejoice in the Holy One of Israel. 20 For the terrible one is brought to nought, and the scorner is consumed, and all that watch for iniquity are cut off: 21 That make a man an offender for a word, and lay a snare for him that reproveth in the gate, and turn aside the just for a thing of nought. 22 Therefore thus saith the LORD, who redeemed Abraham, concerning the house of Jacob, Jacob shall not now be ashamed, neither shall his face now wax pale. 23 But when he seeth his children, the work of mine hands, in the midst of him, they shall sanctify my name, and sanctify the Holy One of Jacob, and shall fear the God of Israel. 24 They also that erred in spirit shall come to understanding, and they that murmured shall learn doctrine.
[AD 420] Jerome on Isaiah 29:1
[Zion] formed the city that David formerly stormed and afterwards rebuilt. Of its storming it is written, “Woe to Ariel, to Ariel”—that is, God’s lion2 (and indeed in those days it was extremely strong).

[AD 420] Jerome on Isaiah 29:1-8
(Chapter 19, verse 1, and following) Woe to Ariel, Ariel the city that David besieged. Year after year is added, the appointed feasts have come to an end. I will besiege Ariel, and she will be sad and mournful; she will be like an Ariel to me. I will encircle you like a sphere, and I will throw up a mound against you, and I will set up siege works against you. You will be brought low, and your speech will come from the ground, and your voice will be like that of a python from the earth, and your speech will mumble from the dust. And it will be like the fine dust of those who blow against you, and like the passing smoke of those who have prevailed against you. And suddenly, immediately, it will be visited by the Lord of hosts, with thunder and earthquake, and with a great voice of whirlwind and tempest, and with the flame of devouring fire. And it will be like the dream of a night vision, the multitude of all the nations that have fought against Ariel, and all who have warred against her and besieged her and prevailed against her. As a hungry person dreams and eats, and when he has awakened, his soul is empty; and as a thirsty person dreams and drinks, and when he has awakened, he is still thirsty, and his soul is empty: so will be the multitude of all the nations that have fought against Mount Zion. Woe to Ariel, Ariel, the city that David besieged! Gather together year after year, eat, for you will eat with Moab; for I will oppress Ariel, and her strength and wealth will be mine, and I will encamp around you like David, and I will send a rampart around you, and set up towers all around you, and your words will be humbled on the ground, and your words will be brought down to the ground. And your voice will be like that of those who speak from the earth, and your voice will weaken to the ground. And the wealth of the wicked will be like dust from a wheel, and like ashes that are carried away, the multitude of those who oppressed you; it will be sudden from the Lord of hosts. For there will be a visitation with thunder, and a great shaking, a powerful storm, and a devouring flame of fire. And they will be like a dreamer at night, the wealth of all the nations that have fought against Ariel, and all who have fought against Jerusalem and gathered against it, and afflicted it. And they shall be like those who hunger and eat in dreams: when they wake up, their dream is in vain, and like one who thirsts and drinks in a dream, when he wakes up, he will still be thirsty, and his soul will have hoped in vain. So shall be the riches of all the nations that have fought against Mount Zion. Because we have interpreted, Woe, in Hebrew it is written Oi (), which is sometimes used in the vocative case, so that Ariel may not mourn, but call out; although in the current context it should be understood as mourning. Ariel is also interpreted as the lion of God; and for the city which Aquila interpreted, πολίχνην, that is, a small town or village, is read in Hebrew as Cariath, which properly means a village, and in Syriac it is called Cartha, hence it is also called a village of forests Cariath Jarim. Finally, in the earlier passage (Isaiah 1:21) where we read: How has the faithful city Zion become a prostitute? for city, Cariath is written, that is, a village: which we can express as a translation of Aquila literally, as a little city. Therefore, Ariel, which means the lion of God, was once called the strongest Jerusalem: or, as others believe, the temple and altar of God that was in Jerusalem. And what follows: Which David conquered, as Symmachus interpreted it, the stronghold of David, and Theodotion, the encampment of David, is read in Hebrew as Hana, which the most learned Hebrews wanted to signify as dwelling place. So if we read: which David conquered, let us refer to that time when David captured the fortress of Zion, while the blind and lame resisted, and Joab, the first, ascended the heights. But according to Symmachus and Theodotion, it should be understood that David restored and fortified it, and a year was added to the year, or subtracted, as Aquila interpreted; and the festivals have passed. For when the temple was destroyed and the Jewish religion abolished, all their festivities perished. And the Lord says that He will encamp around Ariel with the army of Babylon, and it will be sad and mournful when it is destroyed by them. And again under Jesus, the son of Josedech, the high priest, and Zorobabel, the son of Salathiel, were Ezra and Nehemiah, when Haggai and Zechariah prophesied that it would be like Ariel, having the appearance of the ancient temple, but without its magnificence and adornment. Moreover, the Lord threatens that He will surround Ariel with a sphere, and cast a rampart against it, and set up fortifications for its siege, and fulfill what He Himself laments concerning Jerusalem in the Gospel: 'If thou hadst known, even thou, at least in this thy day, the things which belong unto thy peace! But now they are hid from thine eyes. For the days shall come upon thee, that thine enemies shall cast a trench about thee, and compass thee round, and keep thee in on every side, and shall lay thee even with the ground' (Luke 19:42-44). And Jerusalem will be trampled by the nations until the time of the Gentiles is fulfilled. In other words, the same prophet now says that she who was humiliated will speak from the earth, and her voice will be heard from the dust. Her voice will be like that of a python from the earth, and it will murmur like sparrows, so that through these words he may signify the necromancy of the magi, by which they are said to summon souls and hear the voices of thin shades, or rather, of demons. Finally, regarding the python, Aquila interpreted the great one, which is called in Hebrew Cheb (), which the 70 interpreters translated as speaking of the earth. With these words, it is indicated that the ruin of the temple will last until the end of the world, collapsed into ashes and never to be raised again. And so, O Ariel, the army of Roman power will surround you, and they will be compared to an innumerable dust that flies through the air. Therefore, it is not the weakness of their opponents that the dust and ashes are compared to, but the multitude that is equal to countless grains of sand. And this will happen suddenly and quickly, so that in the midst of peace, wars will rise up under Nero, and the Lord of hosts will visit Jerusalem with thunder and earthquake, and whirlwind and devouring fire, which signifies the burning of the temple. But the Romans, after the Jews were defeated and Jerusalem was destroyed under Titus and Vespasian, offered the plundered vessels of God to the Capitol; and they thought that their own power and the favor of the gods, rather than the anger of God, was the reason for what they had done, as if in a dream and in a nightly vision, they will possess all riches. And just as someone who is hungry thinks in their dreams that they are eating, and someone who is thirsty drinks from dry throats, and when they wake up their thirst becomes even stronger, deceived by the empty drink: so the multitude of all nations, who fought against the power of Rome and subjugated to it, will have wealth like a shadow, and a cloud, and a dream of the night, which they will leave behind with their untimely destruction. In the place where we have been placed, all who have waged war and besieged and prevailed against it have been translated to seventy, and all who have fought against Jerusalem, which is not found in Hebrew. In this beginning of the chapter, where we said, 'A year is added to a year, or subtracted,' they are interpreted as 'gather the fruits or produce, year upon year;' 'eat, for you will eat with Moab.' And the meaning is, before the acceptable year of the Lord's preaching comes, indeed two years, of which we read in the Song of Habakkuk according to the Hebrew: 'In the midst of two times you will be known' (Habakkuk 3), 'sow for yourselves in tears so that you may reap in joy' (Psalm 126). It is written in the Gospel according to John that the Lord came to Jerusalem three times during the Passover, which makes two years (John 2:13). However, what follows, 'For you shall eat with Moab,' is not found in Hebrew. We can say that unless the fruits of repentance are gathered for themselves, they will begin to eat with those who do not enter the Church of the Lord forever. The other things in which they seem to disagree are obvious, and from what we have explained, their interpretation is easy. I know that I have read Ariel's interpretation, my light is God's, which is far different. Here the first syllable is written with Aleph and Res: lux autem quae Hebraice dicitur Or, inter Aleph et Res mediam habet litteram Vau, quae in praesenti nomine non habetur. And everything that is now said against Ariel refers to heretics, who consider their doctrine to be the light of God, and they must be fought by the true David: all their solemnities must be taken away, and present joy must be turned into future sorrow: to whom God commands to repent, lest they begin to eat with the Moabites, and be similar to the Gentiles. For he will attack Ariel himself, and he will surround all their power and wealth with his army. And with the towers, that is, the leaders of the Church, he will humble their words on the earth, so that they may not raise their mouth to heaven, but be written on the earth, speak of the earth, and be like dust scattered by the wind. And all the wealth of the wicked will appear in an instant, when he visits them in his majesty, descending in a whirlwind, storm, and fire of punishment; and they will understand that all their wealth, the pomp of their words, and the arguments of their verses, are compared in vain to a dream of someone eating and drinking: those who fight against Jerusalem, the vision of peace; or against Ariel, the strongest lion, and ultimately against Mount Zion, where the city of the Church cannot be hidden.

[AD 253] Origen of Alexandria on Isaiah 29:8
And those who sleep are those who, when they ought to be taking heed and watching with the soul, are not doing this. But by reason of great want of attention they are nodding in resolution and are drowsy in their reflections, such as “in their dreaming defile the flesh, and set at nothing that which is highest in authority, and rail at dignities.” And these, because they are asleep, live in an atmosphere of vain and dreamlike fancies concerning realities. [They do not admit] the things that are actually true, but [they are] deceived by what appears in their vain imaginations. In regard to [them] it is said in Isaiah, “Like as when a thirsty man dreams that he is drinking, but when he has risen up is still thirsty, and his soul has cherished a vain hope, so shall be the wealth of all the nations, as many as have warred in Jerusalem.”

[AD 397] Ambrose of Milan on Isaiah 29:8
Let us speak of him who thought he was happy since he was chief butler and believed that this was the summit and crown of all power, that he would give the cup to the king. This was his glory, this was his grandeur in this world; when he was deprived of this he felt sorrow, and when he was restored to it he rejoiced. But this is a dream, and all worldly power is a dream, not a reality. To be sure, he saw by way of a dream that his preeminent position was restored to him. Isaiah also says that people of this kind are such as take delight in prosperity in this world. One who eats and drinks in his sleep thinks he is filled with food and drink, but when he awakens, he begins to be more hungry; then he understands how insubstantial were that dreamer’s food and drink. Just so, one who is asleep in this world and does not open his eyes to the mysteries of God, as long as he is in a deep corporeal sleep, supposes that such worldly power is of some importance, seeing it, as it were, in his dreams. But when he has awakened, he discovers how insubstantial the pleasure of this world is.

[AD 420] Jerome on Isaiah 29:8
Truly, this life is a dream, a dream of riches; for when we seem to have them within our grasp, immediately they slip away. Isaiah expresses this same thought: “As when a thirsty man dreams he is drinking and awakens faint and dry,” so indeed are the riches of this world; while we are reaching out for them they are gone.

[AD 390] Gregory of Nazianzus on Isaiah 29:9
What are we to do now, my brothers, when crushed, cast down and drunk but not with strong drink or with wine, which excites and obfuscates but for a while, but with the blow which the Lord has inflicted upon us? He says, “And you, O heart, be stirred and shaken, and gives to the despisers the spirit of sorrow and deep sleep to drink.” To [them] he also says, “See, you despisers, behold, and wonder and perish.” How shall we bear his convictions; or what reply shall we make, when he reproaches us not only with the multitude of the benefits for which we have continued ungrateful, but also with his chastisements, and reckons up the remedies with which we have refused to be healed?

[AD 407] John Chrysostom on Isaiah 29:9
Since you are reasonable, I know that after my exhortation you will not permit yourselves to go beyond the bounds of what you need. But now it is appropriate for me to urge you not only to turn aside from drinking to excess but also to avoid the drunkenness that comes without drinking wine. For this kind is more dangerous. Don’t be astonished at what I say, for it is possible to be drunk without wine. That you may know that this is possible, listen to the prophet, who said, “Woe to those who are drunk not from wine.” But what is this drunkenness that does not come from wine? It takes many and varied forms. For anger makes us drunk; so too, vainglory, haughty madness, and all the deadly passions that spring up in us produce a kind of drunkenness and satiety that darkens our reason. For drunkenness is nothing more than the distraction of our minds from their natural ways, the straying of reason and the loss of our understanding.

[AD 407] John Chrysostom on Isaiah 29:9
Yes, it is possible to be drunk without wine; it is possible for a sober person to act as if he is drunk and to revel like a prodigal. If one could not get drunk without wine, the prophet would never have said, “Woe to those who are drunk not from wine”; if one could not get drunk without wine, Paul would never have said, “Do not be drunk with wine.” For he said this as if there were a possibility of getting drunk some other way. And it is possible. A person can be drunk with anger, with unseemly desire, with greed, with vainglory, with ten thousand other passions. For drunkenness is nothing other than a loss of right reason, a derangement and depriving the soul of its health.

[AD 420] Jerome on Isaiah 29:9-12
(Verse 9 and following) Be astonished and amazed: fluctuate and waver, become drunk, not with wine, be moved, not with intoxication. For the Lord has mixed into you the spirit of deep sleep: he will close your eyes, your prophets and leaders who see visions he will cover. And the vision of all will be like the words of a sealed book, which when they give to one who knows letters, they will say: read this, and he will answer, I cannot, for it is sealed. And a book will be given to one who knows not letters, and it shall be said to him, read; and he shall answer, I know not letters. For the spirit of sleep, LXX, is interpreted as compunction: Theodotius, the passing away of the mind: Aquila, καταφορὰν, that is, a heavy sleep; which in Hebrew is called Thardema (), which Scripture commemorates as sent by God to Adam (Gen. II), when woman was made from the rib of his side. And Jonah snored in the same sleep on the ship (Jon. I). But all prophecy after the destruction of Jerusalem and the temple, that is, Ariel, is against the scribes and Pharisees, who, possessing the key of knowledge, do not enter themselves, nor do they allow others to enter. And it is commanded to them, that they should be amazed and astonished, rather according to the septuagint dissolution of the whole body and the excess of the mind, and that they should be moved and fluctuate: staggering not from wine or from strong drink, but from the spirit of sleep or of the Lord's compunction, so that understanding their evil, they may at some point repent, and say with the prophet: I am troubled in my weakness, while the thorn is being fastened to me (Ps. XXXI, 4). Therefore, know this, O scribes and Pharisees, who are the leaders of the Jews, that the Lord will render to you your recompense. For you, who have heard the Lord Savior, did not want to understand, and you closed your eyes so that you would not see him, and you weighed down your ears so that you would not hear. Therefore, he will also close your eyes, you who are the prophets through whom you saw the knowledge of God. Or he will close the eyes of your prophets, who are your leaders. For as the Law and the Prophets testified until John, so that those who do not see may see, and those who see may become blind, as it is written: They will hear the words of the book, even the deaf will hear, and the blind will see and rejoice. For judgment I have come into this world, so that those who do not see may see, and those who see may become blind, that is to say, the people of the nations who were blind, may see and contemplate the Lord. Therefore, it is significant that he did not say that the vision of all the prophets is sealed to all readers, but to you he says, it will be sealed to those to whom I am now speaking, to whom I am foretelling these things that are to come: or He will forever shut the eyes of your leaders, who boasted of being able to see the hidden and secret things according to the Septuagint. And he said to them, 'All the holy Scripture will be closed and sealed to you, so that you, who consider yourselves knowledgeable in the letters of the Law and the prophecies of the prophets, and who constantly meditate on the volumes of Scripture day and night with tireless mouths, may not understand what you read, as it is written in the Book of Revelation of John: 'Who is worthy to open the book and to break its seals?' (Rev. 5:2) And when no one was found worthy to open the seals, he says that he wept; and that he deserved to hear the word of God: 'Do not weep; behold, the lion of the tribe of Judah, the root of David, has conquered, so that he may open the book and break its seals.' But the lion of the tribe of Judah, the Lord Jesus Christ, is he who unseals the seals of the book, not properly of one, as many suppose, of the Psalms of David, but of all the Scriptures, which are one Scripture of the Holy Spirit; and for that reason they are called one book. Concerning which Ezekiel testifies in mystical discourse (Ezek. II), that it was written within and without; in meaning and in letter. Concerning which also the Savior speaks in the Psalms: In the chapter of the book it is written of me (Ps. XXXIX, 9); not of Jeremiah, not of Isaiah, but in all the holy Scripture, which is called one book. Therefore, the Jewish leaders, up to the present day, being unable to read and open the seals, and to reveal the mysteries of the Scriptures, if you were to give them a book to the unlearned people who are devoured by their own teachers, they would admit to not knowing letters and therefore being unable to read. And out of the two evils, it is much lighter to confess ignorance of the law than to boast of prudence and not be able to understand what is said.

[AD 258] Cyprian on Isaiah 29:10
Not to recognize sins lest penance follow is the wrath of God, as it is written: “And the Lord gave to them the spirit of a deep sleep,” lest they actually return and be cured and be healed by their lamentations and just satisfactions after their sins.…The first degree of felicity is not to sin; the second, to recognize the sins committed. In the former, innocence runs upright and unimpaired to save; in the latter, there follows the remedy to cure. They have lost both of these by offending God.… Or do you think, brother, that crimes against God are light matters, small and of little moment, because through them the majesty of an offended God is not sought, because the wrath and fire and day of the Lord are not feared, because, with Antichrist at hand, the faith of a militant people is disarmed while vigor and the fear of Christ are taken away?

[AD 430] Augustine of Hippo on Isaiah 29:10
If they could not believe, what is the sin of a person not doing what he cannot do? But if they sinned by not believing, then they could believe and did not.… Then what will we answer about another testimony of the prophet that the apostle Paul cites, saying, “Israel did not obtain what he was seeking, but the election did obtain it. The rest indeed have been blinded, as it has been written, ‘God gave them a spirit of insensibility, eyes that they should not see, and ears that they should not hear until this present day.’ ”You have heard, brothers, the question proposed; you see, of course, how profound it is. But we answer as best we can. “They could not believe,” because Isaiah the prophet foretold this. But the prophet foretold it because God foreknew that it would be. Why they could not, however, if it should be asked of me, I quickly answer, because they were not willing. For God foresaw their evil will and he, from whom the future cannot be hidden, foretold it through the prophet.
But, you say, the prophet states another cause, not of their will. What cause does the prophet state? That “God gave them a spirit of insensibility, eyes that they should not see and ears that they should not hear, and he blinded their eyes and hardened their heart.” I answer that their will earned even this. For thus God blinds, thus God hardens by abandoning and not helping; and he can do this by a hidden judgment, but he cannot do it by an evil one. The piety of the religious ought altogether keep this unshaken and inviolate; as the apostle says when he was discussing this very same, most difficult question: “What shall we say, then? Is there injustice with God? Not at all!” Therefore, if it is not at all the case that there is injustice with God, either when he helps, he acts mercifully, or when he does not help, he acts justly, because he does all things not with rashness but in judgment. Accordingly, if the judgments of the saints are just, how much more so those of the sanctifying and justifying God! Therefore they are just but hidden.

[AD 235] Hippolytus of Rome on Isaiah 29:11
And that the things spoken of old by the law and the prophets were all sealed, and that they were unknown to people, Isaiah declares when he says, “And they will deliver the book that is sealed to one that is learned, and will say to him, ‘Read this;’ and he will say, ‘I cannot read it, for it is sealed.’ ” It was right and necessary that the things spoken of old by the prophets should be sealed to the unbelieving Pharisees, who thought that they understood the letter of the law, and be opened to the believing. The things, therefore, which of old were sealed, are now by the grace of God the Lord all open to the saints.

[AD 253] Origen of Alexandria on Isaiah 29:11
And clearly, if we hear negligently, if we bring no zeal to learning and understanding, not only are the Scriptures of the law and prophets but also of the apostles and Gospels covered for us with a great veil. I fear, however, lest by too much negligence and dullness of heart the divine volumes are not only veiled to us but also sealed, so that “if a book should be put into the hand of a man who cannot read to be read, he would say, ‘I cannot read’; if it should be put into the hands of a man who can read, he would say, ‘It is sealed.’ ” Whence it is shown that we must not only employ zeal to learn the sacred literature, but we must also pray to the Lord and entreat “day and night” that the Lamb “of the tribe of Judah” may come and himself taking “the sealed book” may deign to open it. For it is he who “opening the Scriptures” kindles the hearts of the disciples so that they say, “Was not our heart burning within us when he opened to us the Scriptures?”

[AD 258] Cyprian on Isaiah 29:11
Isaiah [prophesied] that the Jews would not understand the holy Scriptures, but that they would become intelligible in the last times, after Christ had come: “And all these words shall be to you as the words of a book that is sealed, which, if you shall give to a man that knows letters to read, he shall say, I cannot read, for it is sealed.… But in that day the deaf shall hear the words of the book, and they who are in darkness and in a cloud; the eyes of the blind shall see.”

[AD 339] Eusebius of Caesarea on Isaiah 29:11
For our Lord Jesus Christ did not come as it were to seal up the visions of the prophets. He rather opened and explained those that were of old obscure and sealed, tearing away so to say the seals impressed on them, and taught his disciples the meaning of the Holy Scriptures. Hence he says, “Behold, the lion of the tribe of Judah has prevailed, and he has opened the seals that were set on the book,” in John’s Apocalypse. What are these seals but the obscurities of the prophets? Isaiah knew them well and definitely says too: “And these words shall be as the words of the sealed book.” The Christ of God did not come then to shut up the vision and the prophet but rather to open them and bring them to the light.

[AD 420] Jerome on Isaiah 29:11-12
[Daniel 12:4] "But Thou, O Daniel, shut up the words and seal the book, even to the time appointed. Many shall pass over, and knowledge shall be manifold." He who had revealed manifold truth to Daniel now signifies that the things he has said are matters of secrecy, and he orders him to roll up the scroll containing his words and set a seal upon the book, with the result that many shall read it and inquire as to its fulfilment in history, differing in their opinions because of its great obscurity. And as for the statement, "Many shall pass over" or "go through," this indicates that it will be read by many people. For it is a familiar expression to say: "I have gone through a book," or, "I have passed through an historical account." Indeed this is the idea which Isaiah also expressed in regard to the obscurity of his own book: "And the sayings of that book shall be like the words of a book that is sealed. And if they shall give it to an illiterate man, saying, 'Read it,' he will reply, 'I do not know how to read.' But if they give it to a man who does know how to read and say, 'Read the book,' he will reply, 'I cannot read it, because it is sealed up'" (Isaiah 29:11-12). Also in the Revelation of John, there is a book seen which is sealed with seven seals inside and outside. And when no one proves able to break its seals, John says, "I wept sore; and a voice came to me, saying, 'Weep not: behold the Lion of the tribe of Judah, the Root of David, has prevailed to open the book and break its seals'" (Revelation 5:1-5). But that book can be opened by one who has learned the mysteries of Scripture and understands its hidden truths, and its words which seem dark because of the greatness of the secrets they contain. He it is who can interpret the parables and transmute the letter which killeth into the spirit which quickeneth.

[AD 420] Jerome on Isaiah 29:11
What is the gate that is always closed, through which only the Lord God of Israel enters? Surely it is that about which the Savior spoke in the Gospel: “Woe to you scribes and Pharisees, woe to you teachers of the law, woe to you who hold the key of knowledge. You do not enter yourselves, and you prevent those who would from entering.” Isaiah wrote about the same thing, using the metaphor of a book: “The words of this book are like sealed words; when you give them to a man who cannot read and tell him to read, he will respond: ‘I don’t know how to read.’ And they will give it to a man who is able to read and tell him to read and he will say: ‘I cannot read because it is sealed.’ ” This is the same book whose seal no one can break and open either in heaven or on earth or under the earth, except the one about whom John said in the Apocalypse: “Behold, the Lion of the tribe of Judah, the root and race of David, has conquered so that he can open the book and break its seal.” Before the Savior assumed a human body and humbled himself, taking the form of a servant, the law was closed, the prophets were closed, all knowledge of the Scriptures was closed, and paradise was closed. After he had hung on the cross, however, and said to the thief, “Today you will be with me in paradise,” immediately the veil of the temple was cut and everything was opened. And once the veil has been removed, we will say, “But we all contemplate the glory of the Lord with unveiled face and are being transformed into his very image from glory to glory.”

[AD 420] Jerome on Isaiah 29:11
He who had revealed manifold truth to Daniel now signifies that the things he has said are matters of secrecy. And he orders him to roll up the scroll containing his words and set a seal upon the book, with the result that many shall read it and inquire as to its fulfillment in history, differing in their opinions because of its great obscurity. And as for the statement, “Many shall pass over” or “go through,” this indicates that it will be read by many people. For it is a familiar expression to say, “I have gone through a book,” or “I have passed through an historical account.” Indeed this is the idea that Isaiah also expressed in regard to the obscurity of his own book: “And the sayings of that book shall be like the words of a book that is sealed.”

[AD 420] Jerome on Isaiah 29:11
In the Apocalypse a book is shown sealed with seven seals, which if you deliver to one that is learned saying, “Read this,” he will answer you, “I cannot, for it is sealed.” How many there are today who fancy themselves learned, yet the Scriptures are a sealed book to them, and one which they cannot open save through him who has the key of David, “he that opens and no man shuts; and shuts and no man opens.” In the Acts of the Apostles the holy eunuch when reading Isaiah is asked by Philip, “Do you understand what you are reading?” The man answered, “How can I, except some man should guide me?” To digress for a moment to myself, I am neither holier nor more diligent than this eunuch, who came from Ethiopia … and was so great a lover of the law and of divine knowledge that he read the holy Scriptures even in his chariot. Yet although he had the book in his hand and took into his mind the words of the Lord, no, even had them on his tongue and uttered them with his lips, he still did not know him, who—not knowing—he worshiped in the book. Then Philip came and showed him Jesus, who was concealed beneath the letter. Wondrous excellence of the teacher! In the same hour the eunuch believed and was baptized; he became one of the faithful and a saint. He was no longer a pupil but a master; and he found more in the church’s font there in the wilderness than he had ever done in the gilded temple of the synagogue. These instances have been just touched upon by me (the limits of a letter forbid a more discursive treatment of them) to convince you that in the Holy Scriptures you can make no progress unless you have a guide to show you the way.

[AD 560] Primasius of Hadrumetum on Isaiah 29:11
This is also why Isaiah would say to the Jews: “Behold, all of these words will be to you like the words of a sealed book.” The skilled reader and the illiterate are equally said to be deprived of fruit, since one is prevented by the seal from penetrating what lies hidden within and the other is shackled by ignorance.

[AD 60] Mark on Isaiah 29:13
Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands? He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me. Howbeit in vain do they worship me, teaching for doctines the commandments of men. [Isaiah 29:13] For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do. And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition. For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death: But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free. And ye suffer him no more to do ought for his father or his mother; Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
[AD 60] Matthew on Isaiah 29:13
But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition? For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition. Ye hypocrites, well did Esaias prophesy of you, saying, This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. But in vain they do worship me, teaching for doctrines the commandments of men. [Isaiah 29:13]
[AD 99] Clement of Rome on Isaiah 29:13
Let us cleave, therefore, to those who cultivate peace with godliness, and not to those who hypocritically profess to desire it. For [the Scripture] says in a certain place, "This people honours me with their lips, but their heart is far from me." [Isaiah 29:13] And again: "They bless with their mouth, but curse with their heart." [Psalm 62:4] And again it says, "They loved Him with their mouth, and lied to Him with their tongue; but their heart was not right with Him, neither were they faithful in His covenant." [Psalm 78:36-37] Let the deceitful lips become silent, [and "let the Lord destroy all the lying lips, ] and the boastful tongue of those who have said, Let us magnify our tongue: our lips are our own; who is lord over us? For the oppression of the poor, and for the sighing of the needy, will I now arise, says the Lord: I will place him in safety; I will deal confidently with him." [Psalm 12:3-5]

[AD 258] Cyprian on Isaiah 29:13
What is this obstinacy or what is this presumption to place human tradition before the divine plan and not to notice that God is offended and angered as often as human tradition subverts and disregards the divine precepts? He cries and says through Isaiah, the prophet, “This people honors me with their lips, but their heart is far separated from me. In vain, moreover, they honor me, teaching the commandments and doctrines of men.”

[AD 395] Gregory of Nyssa on Isaiah 29:13
For speaking in this way or in that is not the cause of the thought within us, but the hidden conception of the heart supplies the motive for such and such words, “for from the abundance of the heart the mouth speaks.” We make the words interpret the thought; we do not by a reverse process gather the thought from the words. Should both be at hand, a person may certainly be ready in both, in clever thinking and clever expression; but if the one should be wanting, the loss to the illiterate is slight, if the knowledge in his soul is perfect in the direction of moral goodness. “This people honors me with their lips, but their heart is far from me.” What is the meaning of that? That the right attitude of the soul toward the truth is more precious than the propriety of phrases in the sight of God, who hears the “groanings that cannot be uttered.” Phrases can be used in opposite senses; the tongue readily serving, at his will, the intention of the speaker; but the disposition of the soul, as it is, so is it seen by him who sees all secrets.

[AD 397] Ambrose of Milan on Isaiah 29:13
Again the form of righteousness is described and magnified when Scripture says, “The law of his God is in his heart, and his stride will not be broken.” The law of God is in the heart of the righteous. Which law? It is not the written law but the natural law, because “the law was not laid down for the righteous but for the unrighteous.” The law is in his heart, not superficially, as it is on the lips of the Jews, for “he who believes with his heart is justified.” The one who believes also speaks, but the one who speaks does not necessarily believe. For instance, the people did not believe about whom it is written: “This people honors me with their lips, but their hearts are far from me.”

[AD 407] John Chrysostom on Isaiah 29:13
If we do not see our children deriving any benefit from the teachers we send them to, then we blame the teachers and take our children to other teachers. What excuse will we have for putting so much emphasis on earthly things but not putting emphasis on virtue? Our teachers here [at church] are far more numerous. No less than the prophets and apostles and patriarchs and all righteous people are set over you as teachers in every church. And there is no profit in merely chanting out two or three psalms, making the accustomed prayers at random and then being dismissed. Do you think this is enough for your salvation? Have you not heard the prophet (or rather God through the prophet) say, “These people honor me with their lips, but their heart is far from me”?To keep this from being the case with us as well, then wipe out the letters and impressions the devil has engraved on your souls, and bring me a heart that has been set free from worldly tumults so I can write on it what I want to.

[AD 420] Jerome on Isaiah 29:13-14
(Verse 13, 14) And the Lord said: Because this people draw near with their mouth, and with their lips glorify me, but their heart is far from me, and they fear me by the commandment of men, and teach me the precepts and doctrines of men. Therefore, behold, I will add to do wonders and great marvels among this people: for wisdom shall perish from their wise men, and the understanding of their prudent men shall be hidden. LXX: And the Lord said: This people draw near to me with their mouth, and with their lips honor me; but their heart is far from me: in vain do they worship me, teaching the commandments and doctrines of men. Therefore, behold, I will add to transfer this people: for I will transfer them and destroy the wisdom of the wise, and hide the understanding of the prudent. This testimony was used by the Lord against the Pharisees in the Gospel of Matthew, saying: Why do you also transgress the commandment of God because of your tradition (Matt. 15:3)? And again: Hypocrites, well did Isaiah prophesy about you, saying: This people honors me with their lips, but their heart is far from me. But in vain do they worship me, teaching doctrines and commandments of men (Matthew, 15:9). In this we must note what we have often mentioned before, that the Evangelists and Apostles did not translate word for word; nor did they follow the authority of the Seventy Interpreters, whose edition was read at that time; but they used their own words, as if they were Hebrew and instructed in the Law, without compromising the meaning. However, the people of the Jews draw near to God with their mouth and with their lips, because they boast of having the worship of one God and rejecting idols; but their heart is far from Him, because they do not receive the Lord Jesus Christ. For whoever does not receive the Son, does not receive the Father. And let us learn together how someone approaches God, or how they become distant from Him. For it is written through Jeremiah: 'I am a close God, and not far away,' says the Lord (Jer. XXIII, 23, according to the Septuagint). But we approach God in mind, not in body; just as we read about Moses: 'Moses alone approached God, but the others did not approach' (Exod. XXIV, 2). For he was praying to God in spirit and truth, and he approached him with his mind and spirit. But those about whom it is written that they are taken from the womb and educated from infancy to old age; and in the Law of God they meditate day and night, they do not come near to God, because they accept the traditions of the Pharisees and Scribes, which keep them far from God, and they are whitewashed tombs, which appear beautiful on the outside, but inside are full of dead bones: those who chose Barabbas and rejected the Lord (Matthew 23:27): Therefore, he threatens to add to it, according to the Septuagint, that he will not transfer them to the Assyrians and Babylonians, but disperse them throughout the whole world. According to the Hebrew, he says that he will perform a great astonishment and a marvelous miracle to the Jewish people; so that he may destroy the wisdom of those who do not receive the power of God and the wisdom of God, and may hide and conceal the understanding of the wise, so that they may not find him who is contained in the scripture. The Apostle Paul, writing to the Corinthians, gave testimony of this: 'I will destroy the wisdom of the wise, and the understanding of the prudent I will reject' (1 Cor. 1:19); in other words, he explained the same meaning: not that God, whose father is he, the enemy of wisdom, and through whom all wisdom is in mankind; but with an addition, as it is in Hebrew, he mentioned the wisdom of the people and the wise of that people, that is, the Jewish people. And truly God performed a great miracle in the people after the coming of the Lord Savior, so that at the same time Jerusalem burned, the temple collapsed, and all the knowledge of the teachers was taken away; this being fulfilled what was said above: (Chapter 3, 1 seqq.): Behold, the Lord God of hosts will take away from Jerusalem and from Judah the strong and the strong: all the strength of bread, and all the power of water; the giant and the warrior, and the judge, and the prophet, and the diviner, and the elder, and the fifty-year-old, and the admirable counselor, and the wise architect, and the prudent hearer, and the rest, which the prophetic speech has woven.

[AD 420] Jerome on Isaiah 29:13
This oration is directed against all who act with iniquity. It is summarized neatly in one sentence by the seventy-second Psalm, wherein the prophet says, “How good is the God of Israel to those who are upright in heart! But my feet had almost been moved and my step had nearly slipped, for I was jealous of sinners when I saw the ease of their lives.” This is said particularly against heretics, who, because they are impious, prosper in their ways and generate children of their own, whom they deceive with heresy. They conspire and act with iniquity, all of this for the purpose of plundering the church and of portraying themselves as having been planted by God and having sunk roots and produced children and bore fruit, even while continuing in the wickedness of their intentions. Although they frequently repeat the name of Christ, God does not inhabit them, as Isaiah said: “This people honors me with their lips, but their heart is far from me.”“And you know me, Lord, you see me and you prove my heart to be with you. Gather them as sheep for the slaughter and sanctify them on the killing day.” There is no scandal, he says, because all the impious or heretics flourish only for a while, but “you know me, Lord, and you prove my heart to be with you.”

[AD 420] Jerome on Isaiah 29:13
But if we are impure and unfaithful, all things are profane to us, either due to heresy inhabiting our hearts or to a sinful conscience. Moreover, if our conscience does not accuse us and if we have pious trust in the Lord, “we will pray with the spirit and we will pray with the mind; we will sing with the spirit and sing with the mind,” and we will be far removed from those about whom it is here written: “their minds and consciences are polluted.”“They claim to know God, but they deny him with their deeds. They are accursed, disobedient and repelled by every good deed.” It is about these persons whose minds and consciences are polluted, who claim to know God but deny him with their deeds, that it is said in Isaiah: “This people honors me with their lips, but their heart is far from me.” See how they honor God with their lips while fleeing from him in their heart; professing belief in God with words, their works deny him.

[AD 430] Augustine of Hippo on Isaiah 29:13
Leah, too, received children by her handmaid, from the desire of having a numerous family. Zilpah, her handmaid, is, interpreted, an open mouth. So Leah’s handmaid represents those who are spoken of in Scripture as engaging in the preaching of the gospel with open mouth but not with open heart. Thus it is written of some, “This people honor me with their lips, but their heart is far from me.” To such the apostle says, “You that preach that a man should not steal, do you steal? You that say a man should not commit adultery, do you commit adultery?”

[AD 430] Augustine of Hippo on Isaiah 29:13
This is why he can say, “My friends and neighbors drew near and stood against me; and my neighbors stood far off.” Do you understand what I mean? I have called those who approached him “neighbors,” yet they stood far off; for though they drew near in body, they stood far away in their hearts. Who was so near physically as those who hoisted him onto the cross? Yet who so far away in heart as those who uttered blasphemies? Far distance of this latter kind was mentioned by Isaiah; listen to what he said about being near while really being far away: “This people honors me with its lips (that means, they are physically near), but its heart is far from me.” The same people are said to be near and yet far: near with their lips, far away in their hearts.However, the fearful apostles certainly ran far away, so we can more simply and obviously refer the saying to them, understanding it to mean that some of them drew near and others stood far off. Even Peter, who had been bold enough to follow our Lord, was so far off that when questioned and frightened, he three times denied the Lord with whom he had earlier promised to die.

[AD 430] Augustine of Hippo on Isaiah 29:13
“See, Lord, I will not keep my lips sealed, you know it.” My lips speak, and I will not restrain them. My lips speak to the ears of men and women, but you know my heart. “Lord, I will not keep my lips sealed, you know it.” A human being hears one thing, but God perceives something else. This is emphasized because our proclamation must not be with our lips only, so that it could be said of us, “Do what they tell you, but do not imitate what they do.” Nor must it be said of us, as it was said of that people who praised God with their mouths but not their hearts, “This people honors me with its lips, but its heart is far from me.” Sing with your lips, but draw near to him with your heart, for “the faith that issues in righteousness is in the heart, and the confession that leads to salvation is made with the lips.” This was true of the thief who hung on the cross with the Lord and from the cross acknowledged the Lord. Others failed to recognize the Lord even as he performed miracles, but this man recognized him as he hung upon the cross. The thief was nailed securely in all his limbs: his hands were immobilized by nails, his feet were transfixed, and his whole body fastened to the wood. That body had no use of its other members, but his heart had the use of his tongue. With his heart he believed, and with his lips he made confession. “Lord, remember me when you come into your kingdom,” he said. He hoped for salvation as a distant prospect and would have been content to receive it after a long delay; his hope stretched toward a far-off future, but the day was not delayed. He prayed, “Remember me when you come into your kingdom,” but Christ replied, “Truly I tell you, today you will be with me in paradise.”

[AD 460] Arnobius the Younger on Isaiah 29:13
For God is necessary to all things, but nothing is necessary to him. Because, however, he loved everything he created, by the great grace of his kindness he deemed it worthy to invite the soul to come to him through the law, through trials of virtue, through sorrows of the heart, and through the greatness of human works. He gave not only the bread of angels, therefore, but also the flesh of innumerable birds to the concupiscent, even to the ungrateful. And lest their descendants fail to fear the unpunished crime of the ungrateful, “the wrath of God came upon them when their food was still in their mouths” because they did not believe in his wonders.“Their days vanished in emptiness and their years in partying.” Truly, as I have said, you will not desire to do good unless you are compelled by the fear of suffering evil: “When he killed them,” it says, “they sought him, repented, and came to him immediately.” It was then that “they remembered that God is their helper and their defense.” But only those who said, “You are our God” are the ones who “lied to him with their tongues, for their hearts were not right within them.” Consequently the Lord said, “This people loves me with its lips, but its heart is far from me.” Why these people in particular? Because “they did not have faith in his covenant.” For “without faith,” said the apostle, “it is impossible to please God.”

[AD 465] Maximus of Turin on Isaiah 29:13
Suppose someone says, “We are Christians too; we believe in the Lord, the Savior.” But it is necessary to believe in deed and not in word, not with the tongue but with the heart, lest it also be said to us, “This people honors me with their lips, but their heart is far from me.”

[AD 500] Eusebius of Gaul on Isaiah 29:13
We heard in the Gospel the voice of the Lord saying, “Not everyone who says to me ‘Lord, Lord’ will enter the kingdom of heaven.” To whom does this word pertain? It is doubtlessly to those to whom he had said in another place: “This people honors me with their lips, but their heart is far from me.” We should be vigilant, therefore, that our lives remain consonant and harmonious with the profession of our lips, for if our works cry out to God with sincerity of conscience and probity of life, the mercy of the Lord will turn toward us whom he has heard.

[AD 533] Fulgentius of Ruspe on Isaiah 29:13
God cannot be separated from his creatures by time or space but only by their iniquities. Of the iniquitous, therefore, he said, “This people honors me with their lips, but their heart is far from me.” He also said, “I am a God who draws near, not a God who remains far away. If a man tries to hide, will I not see him? Do I not fill heaven and earth?” Nevertheless, blessed David himself said, “Those who distance themselves from you will perish.”

[AD 542] Caesarius of Arles on Isaiah 29:13
According to what the prophet says, “This people honors me with their lips, though their hearts are far from me.” To them the Holy Spirit exclaims, “But to the wicked person God says, ‘Why do you recite my statutes and profess my covenant with your mouth?’ ” It is as if he were saying it does you no good to praise God. It is profitable for those who live well to praise him, but if you praise him and do not abandon your sins, it avails nothing. Why do you praise me? Listen to the Scriptures say, “Unseemly is praise on a sinner’s lips.” If you live a wicked life and say good things, you do not yet praise God. Again, if when you have begun to live well you attribute it to your own merits, you do not yet praise God. I do not want you to be a robber deriding the cross of our Lord, but neither do I want you as his temple to throw away his merits in you and conceal his wounds.

[AD 585] Cassiodorus on Isaiah 29:13
The habit of sinners is … after they have achieved the aspiration of their most wicked plans, they then give thanks to the Godhead since they have attained their wish. But they in their utter wretchedness do not realize that he originates only successful aspirations that are holy. “They shall bless” not with their hearts but their mouths, the source of hypocritical utterances for the most part. As Isaiah says, “This people glorify me with their lips, but their heart is far from me.”

[AD 585] Cassiodorus on Isaiah 29:13
If the fear of God is not mingled with love, he is not sought in the heart’s entirety. It is certain that it is the keenest of sins for a person to say that he confesses to him with his tongue, while his heart deep down is at odds with him; does God not know all that goes on within us?… He does not hear merely what the tongue proclaims, as a human person does. It is the person who faithfully believes his testimonies who truly loves him. Fides (faith) gets its name from words uttered (quod fiant dicta). The Lord himself offers a testimony like this verse when he says, “This people glorifies me with their lips, but their heart is far from me.”

[AD 585] Cassiodorus on Isaiah 29:13
Though we never withdraw ourselves from the Lord since he is wholly everywhere, we nonetheless become distant when we are displaced through the nature of our deeds.

[AD 55] 1 Corinthians on Isaiah 29:14
For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent. [Isaiah 29:14] Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world? For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe. For the Jews require a sign, and the Greeks seek after wisdom: But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. Because the foolishness of God is wiser than men; and the weakness of God is stronger than men. For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called: But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are: That no flesh should glory in his presence. But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: That, according as it is written, He that glorieth, let him glory in the Lord.
[AD 215] Clement of Alexandria on Isaiah 29:14
It is of … those … who practice idle discourse that God’s Scriptures say superbly: “I will destroy the wisdom of the wise and bring to nothing the cleverness of the clever.”

[AD 258] Cyprian on Isaiah 29:14
Philosophers also declare that they pursue this virtue, but their patience is as false as is their wisdom, for how can anyone be either wise or patient unless he knows the wisdom and patience of God? For he himself warns and states concerning those who think that they are wise in this world: “I will destroy the wisdom of the wise, and the prudence of the prudent I will reject.” … Therefore, if their wisdom is not true, their patience cannot be true either. For if that man who is humble and meek is patient, and yet we see that the philosophers are not humble or meek but very pleasing to themselves, and displeasing to God by the very fact that they are pleasing to themselves, it is evident that patience is not found where there is the arrogant boldness of an affected freedom and the shameless boasting of the proud and half-naked breast.

[AD 420] Jerome on Isaiah 29:14
From my youth up until now I have spent many years in writing various works and have always tried to teach my hearers the doctrine that I have been taught publicly in church. I have not followed the philosophers in their discussions but have preferred to acquiesce in the plain words of the apostles. For I have known that it is written, “I will destroy the wisdom of the wise and will bring to nothing the understanding of the prudent,” and “the foolishness of God is wiser than men.” This being the case, I challenge my opponents thoroughly to sift all my past writings and, if they can find anything that is faulty in them, to bring it to light. One of two things must happen. Either my works will be found edifying and I shall confute the false charges brought against me; or they will be found blameworthy and I shall confess my error.

[AD 430] Augustine of Hippo on Isaiah 29:14
But perhaps Pelagius thinks that the name of Christ is necessary so that we may learn by his gospel how we ought to live, but not so that by his grace we may also be helped to lead good lives. At least, this consideration should lead him to admit that there are wretched shadows in the human soul, which knows how to tame a lion but not how to live. But are a free will and the natural law sufficient for us to know this? This is the “wisdom of speech” by which “the cross of Christ is made void.” But he said, “I will destroy the wisdom of the wise,” because that cross cannot be made void. And immediately is overthrown that “wisdom” through the “foolishness of preaching,” by which those who believe are healed. For if the natural power through free will is sufficient for us not only to know how we ought to live but actually to live well, “then Christ died in vain,” “then is the scandal of the cross made void.” … Ignorant of the justice of God, you are seeking to establish your own justice, and you have not submitted to the justice of God. For even as Christ is the end of the law, so also is he the savior of corrupted human nature, to justice for all who believe.

[AD 215] Clement of Alexandria on Isaiah 29:15
He forgets the words of the Educator: “Every man that passes beyond his own bed, who says in his soul: Who sees me? Darkness compasses me about, and the walls cover me, and no man sees my sins: whom do I fear? The Most High will not remember.” Such a person is most wretched, for he fears only the human observation and thinks to hide from God. “He does not know,” Scripture continues, “that the eyes of the Most High Lord are far brighter than the sun, beholding all the ways of men and looking into the most hidden parts.” Another time, the Educator gives warning through Isaiah: “Woe to you who made your counsel in secret and say: Who sees us?” A light that can be seen by the senses may pass unnoticed, but that which illumines the mind cannot be ignored.

[AD 420] Jerome on Isaiah 29:15-16
(Vers. 15, 16.) Woe to those who are deep in heart, who hide their counsel from the Lord. Their works are in darkness, and they say: Who sees us, and who knows us? Your thoughts are perverse, as if clay should think against the potter, and the work should say to its maker: You did not make me; and the thing formed should say to its former: You do not understand. LXX: Woe to those who make deep counsel, and their works are in darkness, and they say: Who sees us? Who will know us and what we do? Will we not be regarded as clay in the potter's hands? Will the work say to the one who made it, 'You did not make me wisely,' or the creation to its creator, 'You did not make me?' Against those of whom he spoke before, I will destroy the wisdom of the wise and reject the intelligence of the intelligent. As the prophet writes, I will hide it away. Now even the word of God is directed towards those who are wise in themselves and prudent in his sight. From these things it can be very well understood: 'They have failed examining with examination' (Psalm 63); since it is written about the wisdom of God: 'For if someone is perfect in the sons of men without your wisdom, he will be considered as nothing' (Wisdom 3). Those who believe that God is unaware of their plans because their works are in darkness, say: 'Who sees us? And who knows us?' But this is also said by the wise of this world, and by the masters of heretics, and by the Pharisees of the Jews, because no one understands them; not remembering what is said to God: 'Darkness will not obscure you, and the night will be illuminated like day' (Psalm 138, 12). And as his darkness, so also his light (Genesis 3). Deceived by this error, Adam and Eve, upon hearing the sound of footsteps walking in the paradise of God, hid themselves under the tree in which was the knowledge of good and evil; and Cain also, saying: If you cast me out today from your presence, I will hide (Genesis 4, 14), thought foolishly that God was ignorant. And through Amos, it is said of the wicked and sinners: If they hide themselves from my eyes in the depths of the sea: there I will command the serpent and it will bite them (Amos 9, 3). Even if someone is wise and of fervent genius, if they do not have God's wisdom and teaching, let us say of them: Unless the Lord builds the house, those who build it labor in vain. Unless the Lord guards the city, the one who guards it stays awake in vain (Psalm 127:1-2). Let us make ourselves similar: Unless the Lord assists knowledge, the one who thinks themselves wise labors in vain. Unless the Lord keeps our hearts in every watch, the one who thinks it can be kept by their diligence stays awake in vain. He says, 'Your thinking is perverse, to think that the Creator does not know what He has made, and that the Creator is ignorant of His creation, as if clay were to say to the potter and to its maker, 'You did not make me,' or 'You did not make me well,' and you do not understand your own creation.' The Apostle also uses this testimony in other words to refute the slander of humans and to discuss the deep knowledge of God with the Romans: 'O man, who are you to answer back to God?' Does the thing formed say to its creator, 'Why have you made me like this?' Does not the potter have power over the clay, to make one vessel for honor and another for dishonor? (Romans 9:20-21). In all these things, the following rule is always to be observed: that the Evangelists and Apostles may without harm to the sense be translated into Greek from Hebrew, as it seems best to them.

[AD 56] Romans on Isaiah 29:16
And not only this; but when Rebecca also had conceived by one, even by our father Isaac; (For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;) It was said unto her, The elder shall serve the younger. As it is written, Jacob have I loved, but Esau have I hated. What shall we say then? Is there unrighteousness with God? God forbid. For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. So then it is not of him that willeth, nor of him that runneth, but of God that showeth mercy. For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might show my power in thee, and that my name might be declared throughout all the earth. Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth. Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will? Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus? [Isaiah 29:16] Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? What if God, willing to show his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction: And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory, Even us, whom he hath called, not of the Jews only, but also of the Gentiles?
[AD 407] John Chrysostom on Isaiah 29:16
If a man seems more comely to look upon than clay, this difference was not produced by a change of nature but by the wisdom of the craftsman. Why? Because you are no different from the clay. If you refuse to believe this, let the coffins and the cinerary urn convince you. And you will know that this is the truth if you have gone to visit the tombs of your forebearers. Therefore there is no difference between the clay and the potter.

[AD 430] Augustine of Hippo on Isaiah 29:16
Scripture says to Pharaoh, “To this purpose have I raised you that I may show my power in you; and that my name may be declared throughout all the earth.” Then, making a conclusion to both passages, he says, “Therefore he has mercy on whom he will and whom he will he hardens.” Obviously he treats neither of these with injustice but both with mercy and truth; in spite of that there is an uprising of insolent weakness on the part of those who attempt to comprehend the unsearchable depth of the judgment of God according to the interpretations of the human heart. The apostle refutes this view when he says, “You will say therefore to me: Why does he then find fault? For who resists his will?” Let us imagine this as said to us. What other answer should we make than the one he made? If such ideas disturb us also because we, too, are human, we all have need to listen to the apostle saying, “O man, who are you that replies against God? Shall the thing formed say to him that formed it: Why have you made me thus? Or has not the potter power over the clay, of the same lump to make one vessel unto honor, another unto dishonor?” If this lump of clay were of such indifferent value that it deserved nothing good any more than it deserved anything evil, there would be reason to see injustice in making of it a vessel unto dishonor. But when, through the free will of the first man alone, condemnation extended to the whole lump of clay, undoubtedly if vessels are made of it unto honor, it is not a question of justice not forestalling grace, but of God’s mercy. If, however, vessels are made of it unto dishonor, it is to be attributed to the judgment of God, not to his injustice—far be from us the thought that there could be any such with God! Whoever is wise in this matter with the Catholic church does not argue against grace in favor of merit, but he sings mercy and judgment to the Lord, that he may not ungratefully deny his mercy or unjustly upbraid his judgment.

[AD 649] Sahdona the Syrian on Isaiah 29:16
God comes down to the level of sinful men and women; the good Lord speaks with his rebellious servants; the holy one calls those who are impure to forgiveness. Humanity created out of mud addresses its Fashioner with familiarity; dust converses with its Maker. Let us, therefore, show awe when we sinners stand in the presence of this Majesty and speak. Even though we are so impure in our deeds, he draws us close to the sight of himself in the spirit; let us therefore repeat with trembling the words of the blessed prophet Isaiah: “Woe is me, for I am dazed: I am a man of unclean lips, yet my eyes have beheld the King, the Lord Almighty.”

[AD 420] Jerome on Isaiah 29:17-21
(Verse 17 and following) Will not Lebanon soon become a fruitful field, and the fruitful field be regarded as a forest? On that day the deaf will hear the words of the scroll, and out of gloom and darkness the eyes of the blind will see. The meek will obtain fresh joy in the Lord, and the neediest people will exult in the Holy One of Israel. For the tyrant shall be no more, and the scoffer shall cease to be; all those alert to do evil shall be cut off. Why do people sin in words and overthrow the one who argues at the gate? And they turned away in vain from the just. Let the Jews and friends of simple history answer, those who seek fruit not on the tree, but only leaves and the shadow of words, which quickly wither and perish. How is it that in the coming of the Lord Savior (because from the time of Isaiah until the incarnation of the flesh, for the comparison of eternity, it is a short and small span of time) the mountain of Lebanon turned towards Phoenicia and moved to Mount Carmel? It is called in Hebrew Chermel, and it is near the border of Palestine and Phoenicia, overlooking Ptolemais: although another mountain in the holy scriptures is called Mount Carmel, where there was Nabal the Carmelite (1 Samuel 25), a foolish and wicked man, who had a wife named Abigail, who married David after her husband died; while her husband was alive, she could not marry David, so as not to be called an adulteress if she were associated with another man; and how is Carmel considered a desirable place and unfruitful trees? But since they are unable to express it, let them listen to Libanus, which means "whiteness", referring to the people of the Gentiles who, having been washed in the Lord and cleansed of their former filth, ascend as a whole world. They rely on the person of the Church as the bride of the Savior, and it is said about them in the Song of Songs: Who is this who comes up, shining white, leaning on her beloved? (Cant. VIII. 5) And let this people be transferred to Carmel, which means the knowledge of circumcision, so that they may recognize the mysteries of spiritual and true circumcision, and be in the place of the former people of the Jews. As for those who refuse to accept Christ, let them be considered as thorns and barren trees, which cannot praise the Lord with fruitful trees. But when Lebanon is changed into Carmel, and Carmel into a forest, then those who were deaf and could not hear the words of the prophetic book (of which we have spoken before, that all Holy Scripture is called one book, as Ecclesiastes says: 'The sayings of the wise are like goads, and like nails fixed deep in, given by one Shepherd') will hear and speak, to whom the Savior will say: Ephphatha (which means, 'Be opened') (Mark 7). And that which we translate, the eyes of the blind shall see darkness and mist, the interpretation of which is easy; Aquila and Theodotion and Symmachus translated: The eyes of the blind shall see darkness and mist: to show the sacraments of Christ to the people of the nations, who were previously blind, according to what is said: Dark water in the clouds of the sky (Ps. 17, 12). And in the same psalm it is written about God: He set darkness as his hiding place (Ibid. 12). And in Proverbs we read: This wise person will be wiser by hearing these things and will have possession of prudent governance and will understand parables and dark sayings spoken by the wise and enigmas (Prov. I, 5, 6). Moreover, Moses, in order to understand and see God (Exod. XX), entered into a cloud and darkness, of which it is said in the Psalm: Darkness is under his feet (Ps. XVII, 10). But when the blind or those who are initiated into mystical matters have first beheld these things or have lifted up their eyes from blindness and darkness to see, so that true light may arise for those sitting in darkness and the shadow of death, then the meek, of whom it is written: Blessed are the meek, for they shall inherit the earth (Matt. V, 4), whether they be the poor, of whom the leader says in the Psalms: This poor man cried out, and the Lord heard him (Ps. XXXIII, 7); and he who judges the poor people and will save the children of the poor (Ps. XIII, 9), of whom it is said to the Jews: You have despised the counsel of the poor, they shall add joy in the Lord, so that he who glories, may glory in the Lord (II Cor. X); and poor men or those in despair and contempt by men, who did not have knowledge of the law before, will exult in the Holy One of Israel, who says: Be holy, for I am holy (Lev. XI, 44). And there is rejoicing for every downfall: for he who prevailed has fallen. The deceiver, or the arrogant and proud one, is brought to an end, who said: With my strength I will do it, and with my wisdom I will remove the boundaries of nations and destroy their strength; who deceived everyone to such an extent that even the holy one said: My loins are filled with deceits (Psalm 38:8). And all those who kept watch over wickedness have been cut off or destroyed, for their wicked vigilance does not cease: they caused the whole human race to sin by blaspheming the Word of God and placing their mouths in heaven. But the demons, themselves wicked, made all men sin in speech, blaspheming with various teachings, and they would overthrow the one reproaching in the gate and in judgment as much as they could, and they made him turn away from righteousness, who was in the gates of the daughter of Zion, exalted from the gates of death; and he rebuked those who hated him in the gates. These things we understand concerning the devil and his angels, the Nazarenes consider them to be spoken against the scribes and Pharisees, because they failed in their second attempt, who before mocked the people with their wicked traditions; and they watched day and night to deceive the simple, who made men sin against the Word of God, to deny Christ the Son of God.

[AD 735] Bede on Isaiah 29:17
Note that [Paul] taught Greeks in Jerusalem, and Jews in Damascus which is a Gentile city, even though this should signify that Gentiles were to be included in the city of God and Jews were to fall into the faithlessness of the Gentiles, in accordance with what Isaiah said, “Lebanon shall be changed into Carmel, and Carmel shall be regarded as a wasteland.”

[AD 735] Bede on Isaiah 29:18
Neither was heaven created in any six-day period and the stars illuminated and the dry land separated from the water and the trees and vegetation planted. Rather, Scripture customarily uses “day” to denote an unspecified period of time, as the apostle did when he said, “Behold, this is the day of salvation.” He was not referring to a particular day but to the entirety of the time of the present life in which we labor for eternal salvation. The prophet also spoke not of one specific day but of numerous moments of divine grace, saying, “In that day, the deaf will hear the words of this book.” Moreover, it is difficult to understand how in one day God made heaven and earth and all the brush of the field and every plant of every region, unless we say that all creatures were created simultaneously in formless matter, according to which it is written: “He who lives forever created all things together.”

[AD 420] Jerome on Isaiah 29:22-24
(Verses 22 onwards) Therefore, the Lord says to the house of Jacob, who redeemed Abraham: Jacob will not only be ashamed, but his face will also turn red. But when he sees his children, the works of my hands, in their midst sanctifying my name, they will sanctify the Holy Jacob, and they will proclaim the God of Israel. And those who wander in spirit will gain understanding, and murmurers will learn the Law. (LXX: Therefore, the Lord says about the house of Jacob, whom he overcame from Abraham: Jacob will not only be ashamed, but his face will not change now; but when he sees his children, my works, they will sanctify my name because of me, and they will sanctify the Holy Jacob, and they will fear the God of Israel, and those who wander in spirit will gain understanding, and murmurers will learn obedience, and what follows ÷ and those with stammering tongues will learn to speak peace. ** Note: marked with an obelus.) When the deaf hear, says he, the words of the book, and the eyes of the blind see: the Lebanus has been turned into Charmel, and Charmel is regarded as a forest, so that the meek and the poor rejoice in the Lord, and the proud and the scoffers are overcome: then Jacob, who now is not yet ashamed, will be put to shame. But this refers to the times of Isaiah. And his face will blush, so that blushing and confusion may be the occasion of salvation, especially when he sees his sons, that is, the Apostles and apostolic men, who were from the race of the Jews, performing miracles in the midst of the nations of the Lord, and preaching the name of Christ to the Gentiles, and saying: Our Father, who art in heaven, hallowed be thy name (Matt. 6:9). For they shall sanctify the Holy One who was born of Jacob, and they shall teach the God of Israel among the nations, so that, the idols being abandoned, they may say: how false were the idols that our fathers possessed, and there is no power in them; and then those who now wander in spirit will understand the knowledge of God, and those who once murmured against the Lord in the wilderness will learn the Law, of which they previously had no knowledge. For if they had received Moses, they would have also received the Lord Jesus Christ, because Moses spoke of him. What we have translated in the beginning of the chapter according to the Hebrew: This is what the Lord says to the house of Jacob, who once redeemed Abraham, and brought him out from the Chaldeans, and led him into the promised land (Gen. XI), is clearly evident. However, what the Seventy translated: This is what the Lord says about the house of Jacob, which he separated from Abraham, can be understood as meaning that he has separated the Scribes and Pharisees, who blasphemed the Lord, from Abraham, who saw the day of the Lord and rejoiced (John VIII). For if they were the children of Abraham, they would do the works of Abraham. And the Apostle argues that those who have the likeness of the faith of Abraham, that is, the people of the Gentiles, who are called children of Abraham not by works but by faith (Hebrews XI).
