1 Thus saith the LORD, Where is the bill of your mother's divorcement, whom I have put away? or which of my creditors is it to whom I have sold you? Behold, for your iniquities have ye sold yourselves, and for your transgressions is your mother put away. 2 Wherfore, when I came, was there no man? when I called, was there none to answer? Is my hand shortened at all, that it cannot redeem? or have I no power to deliver? behold, at my rebuke I dry up the sea, I make the rivers a wilderness: their fish stinketh, because there is no water, and dieth for thirst. 3 I clothe the heavens with blackness, and I make sackcloth their covering. 4 The Lord GOD hath given me the tongue of the learned, that I should know how to speak a word in season to him that is weary: he wakeneth morning by morning, he wakeneth mine ear to hear as the learned. 5 The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back. 6 I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting. 7 For the Lord GOD will help me; therefore shall I not be confounded: therefore have I set my face like a flint, and I know that I shall not be ashamed. 8 He is near that justifieth me; who will contend with me? let us stand together: who is mine adversary? let him come near to me. 9 Behold, the Lord GOD will help me; who is he that shall condemn me? lo, they all shall wax old as a garment; the moth shall eat them up. 10 Who is among you that feareth the LORD, that obeyeth the voice of his servant, that walketh in darkness, and hath no light? let him trust in the name of the LORD, and stay upon his God. 11 Behold, all ye that kindle a fire, that compass yourselves about with sparks: walk in the light of your fire, and in the sparks that ye have kindled. This shall ye have of mine hand; ye shall lie down in sorrow.
[AD 253] Origen of Alexandria on Isaiah 50:1
Hear what the prophet says: “You have been sold for your sins, and for your iniquities I sent your mother away.” You see, therefore, that we are all creatures of God. But each one is sold for his own sins and, for his own iniquities, separates from his Creator. We, therefore, belong to God insofar as we have been created by him. But we have become slaves of the devil insofar as we have been sold for our sins. Christ came, however, and “bought us back” when we were serving that lord to whom we sold ourselves by sinning. And so [Christ] appears to have recovered as his own those whom he created; to have acquired as people belonging to another, indeed, those who had sought another Lord for themselves by sinning.

[AD 397] Ambrose of Milan on Isaiah 50:1
Joseph was sold in Egypt because Christ was going to come to those to whom it was said, “It was for your sins that you were sold,” and thus he redeemed with his own blood those who had been sold by their own sins. But Christ was sold because he took our condition on himself, not our fault. He is not held to the price of sin, because he himself did not commit sin. And so he made a contract at a price for our debt, not for money but for himself. He took away the debtor’s bond, set aside the moneylender, freed the debtor. He alone paid what was owed by all.

[AD 420] Jerome on Isaiah 50:1
(Chapter 50, Verse 1) Thus says the Lord: Who is this bill of divorce of your mother, whom I have sent away? Or to whom have I sold you? Behold, because of your iniquities you were sold, and because of your sins your mother was sent away. For I came and there was no man; I called, and there was none to answer. LXX: Thus says the Lord: What is this bill of divorce of your mother, whom I have sent away? Or to whom have I sold you, to the creditor and exactor of me? Behold, you have been sold for your sins, and for your iniquities I have dismissed your mother. For I came, and there was no man: I called, and there was none that obeyed. After the calling of the nations, and the kings and princes, the nourishers and the nurses, and the captivity of the strong and the mighty, whose prey was distributed to the Apostles, and after the fury of the demons, who were satiated with their own flesh and intoxicated with their own blood: when all flesh knew that the Redeemer and the strong God of Jacob himself, speaks to the people of Judah concerning Zion, which he had previously said: The Lord has forsaken me, and the Lord has forgotten me. Do you think that I, through my stubbornness, have cast down your earthly Jerusalem and that because of my rigid mind, I gave her a bill of divorce, and rather, as is true, you understand that she has departed from me because of her own fault? For when I said to her, 'Stop acting unjustly, learn to do good, listen to me,' she did not want to listen but turned her back on me as she departed. Therefore, I spoke to her children: Woe to them, for they have departed from me. Those who acted wickedly against me have been made evident. And against her, You, your departure and your wickedness will reprove you; and you will know that it is evil for you to leave me. But perhaps you cannot show a certificate of divorce, and one of my creditors demanding money, with me having nothing to give back, do you accept a repayment of debt? It is not so: but I will show you why I have abandoned the mother with her children. Your crimes and sins have sold you to demons, so that, entangled in the pleasures of this present age, you would abandon both your parent and that wife. I could not continue to hold your adulterous mother any longer, but I allowed her to leave willingly. And it is true that each person is sold by their own sins, as we are abandoned by our own free will, either led to goodness or led to evil, and the Apostle Paul teaches: 'But I am carnal, sold under sin' (Rom. VII, 14). For whoever commits sin is a slave to sin (John VIII). And just as misers and plunderers are slaves to money, so every sin dominates sinners. To whom it is said: Let not sin reign in your mortal body (Rom. VI, 12). But so that you may know, I did not reject your mother’s soul; rather, she withdrew of her own accord. After many benefits, I assumed a human body, and I spoke not through the prophets, but in person. I came, and I was not a man, nor a human being. For all men, leaving the image of a man and of a human being, took on the images of beasts and serpents. Therefore, due to her wickedness, it is said to Herod: Go, and tell this fox (Luc. XIII, 32). And to the Pharisees: 'Brood of vipers' (Matthew 23:33). And to the lustful: 'They have become insane horses longing for females' (Jeremiah 5:8). And about the indulgent: 'Do not cast your pearls before swine' (Matthew 7:6). And to the shameless: 'Do not give what is holy to the dogs' (Matthew 7:6). And in general, about everyone: 'The vision of the beasts that were in the wilderness' (Isaiah 30). So the Lord came, but did not find a man. For when man was in honor, he did not understand; he was compared to dumb animals and became like them' (Psalm 49:13). I called, he said, them as if they were rational animals, and I said: Incline your ear to the words of my mouth (Psalm 77), and my people did not hear my voice. I cried out, and said: Let anyone who is thirsty come to me, and let them drink (John 7:37). And in another place: Come to me, all who labor and are heavy laden (Matthew 11:28). And there was no one to hear; therefore I spoke to them in the Gospel: You have not seen the form of God, nor have you heard his voice, because you do not have his word abiding in you (John 5:37, 38).

[AD 444] Cyril of Alexandria on Isaiah 50:1
God never sends away anyone who makes his home with him, and he rejects none of those who walk uprightly. He allows them to be forever associated and firmly joined to him as a way of obtaining help. However, everyone who opposes or fights against his divine teaching falls completely away from the glory of God and shows that he is a lover of pleasure rather than a lover of God. Therefore, like one who lived with the mother of the Jews God says, “What kind of bill of divorce did your mother have when I sent her away?” For no one could prove that I hated her and despised her. Instead, he would rather have to accuse her of deserting me.… It says, “I came,” that is, I took human form and appeared to those in Israel, and there was no man among them, that is, no one with a heart who was able to recognize the season of redemption. “I called, but no one listened.” … For he was in a form like ours, and yet he was God the Word, having become man by taking on flesh born of a woman. But those who knew this and were not ignorant of the depth of the mystery of his divinity knew that he was able to do all things because he was God by nature and suitable for the redemption of everyone under heaven.

[AD 528] Procopius of Gaza on Isaiah 50:1
For he compares himself with a husband who is his wife’s master and householder. For what master is obliged to let you go? But you have been transgressors from the beginning and so cast out, “sold to your iniquities,” enslaved by them, who were before independent and free. And finally, since God did not wait for you but came to you, and coming down to a lowly dignity, he became man. But no one answered him as he was calling for salvation. He adds “there was not one person,” since the mass of those not answering are deemed to be as nothing. Whereas those who answered, a few out of the nations will be exempted from the fate of the nations; as with Lot in the days of Sodom, they will be brought out. For the Lord did not think fit to make the holy land available to many. And the barren fig tree was a sign of that.

[AD 850] Ishodad of Merv on Isaiah 50:1
“Did my hand reap the crop? And did it drop?” that is, Is it tired and weakened? He is inspired by what happens to the harvesters, from whose hands the ears escape. For he teaches, through these words, that it is from them that the cause of their afflictions derives and not from him.

[AD 420] Jerome on Isaiah 50:2
So that you might know that your mother was not rejected by me but deserted of her own will, after many benefits I put on human flesh and not through any prophets but actually present myself I spoke forth: “I have come, and there was not a man” or a person. For all people, abandoning the image of humans, adopted the images of beasts and serpents. Thus it was said to Herod on account of his wickedness, “Go and tell that fox,” or to the Pharisees, “brood of vipers.” … I have called them as if they were rational animals.… We can say that although he is the accomplisher of such great signs and he makes the sky and earth and sea to serve his uses, even he could not avoid the cross.

[AD 420] Jerome on Isaiah 50:2
(Verse 2.) Has my hand been shortened and become small, that I cannot redeem? Or is there no power in me to deliver? Indeed, I will make the sea a desert, I will dry up the rivers. The fish will rot without water and die of thirst. I will clothe the heavens in darkness and make sackcloth their covering. LXX: Can my hand not save, or is it not strong enough to deliver? Behold, by my threat I will make the sea a desert, and I will dry up the rivers, and their fish will wither away because there is no water, and they will die of thirst. And I will clothe the sky in darkness, and I will make its covering like sackcloth. Against those who believed that the Lord could not deliver his people from captivity, he sets forth overwhelming proof and most abundant examples. He made the Red Sea passable for his people (Exod. XIV), he dried up the flowing waters of the Jordan, and as the rivers in Egypt dried up, he turned their fish into rot. (Exod. VII). And He who made the darkness in Egypt palpable for three days, so that the sky appeared covered as if with a sack and with darkness, certainly could also deliver His people from danger. Whether because He had said before, 'I came, and there was no man; I called, and there was none to hear,' we can say this: He who is the performer of such great signs, who makes the sky, the earth, and the seas serve His will, could also escape the cross himself, saying in the Gospel, 'Do you think that I cannot appeal to my Father, and he will at once send me more than twelve legions of angels?' (Matthew 26:53) According to the anagoge, the sea becomes a desert through the rebuke of the Lord, when all the bitterness of this world is dried up, and the rivers are desolated, about which the spiritual dragon said in Egypt: 'The rivers are mine, and I have made them' (Ezek. XXIX, 9). And about which we read in another place: 'What have you to do with the ways of the Assyrians, to drink the waters of the rivers?' (Jer. II, 18). Also, the fish that are thrown into the sea with nets rot, having been separated from the good fish. And what follows: I will clothe the heavens in darkness, and its covering will be like sackcloth; or everything that is above us, let us understand as heaven, just as those flying creatures that are in the air are called celestial; and the opposing powers are said to be celestial, which move between heaven and earth. Or certainly, the heavens are clothed in darkness when they are covered with clouds. According to what is written: Who covers the heavens with clouds, and gives rain to the earth (Psalm 147:8). And in the threat of drought, God says: I will make the sky bronze and the earth iron (Deut. XXVIII, 23). Not that the nature of the elements is changed, but that the magnitude of the punishment is shown through bronze and iron. Philosophers say that clouds are lifted no more than ten stadia above the earth and hide the brightness of the sun. Therefore, the sky is not wrapped in a sack, but the air beneath, with the light of the sky blocked, is darkened by the darkness of the clouds. We can interpret that the heavens are covered with darkness, and being covered with a sack, in such a way that we say all are under sin, and even the holy ones need the mercy of God.

[AD 444] Cyril of Alexandria on Isaiah 50:2
No one who views things correctly thinks God possesses a physical body. It is only that the holy Scriptures speak in a human fashion about him. For those of us in simple and crass bodies can think in no other way, except that these things are adapted for us by a range of metaphors, so that in the perception of visible things we are able to know in part about the divine and higher being, which is higher than all bodily imaginings. Observe how in these words the message is adapted to human understanding.

[AD 458] Theodoret of Cyrus on Isaiah 50:2
Then he recalls for them what he has accomplished: “Behold, by my rebuke I will dry up the sea and make rivers a wilderness; and their fish shall be dried up because there is no water and shall die for thirst.” Symmachus has rendered this passage as if it concerns events already accomplished: “Behold that at my rebuke I have dried up the sea, that I have made the rivers a desert and that their fish have been putrified for lack of water.” Thus, the God of the universe accomplished this at the time he delivered them from the bondage of the Egyptians: it was then that he parted the Red Sea, divided the Jordan in two and revealed that the fish in its bed were dead from deprivation of its nourishing waters. If, however, one likewise understands this passage [to relate] to the future, as the Septuagint desires [to do], one will do no violence to the senses. It indicates from great miracles that he will also be able to accomplish small things: if it was easy for me to dry up the sea, he says, and to interrupt the course of rivers, it would have been much easier to annihilate an army that was marching against you.

[AD 458] Theodoret of Cyrus on Isaiah 50:2
I have many times endured your belief in idols and the infinite number of iniquities that you have perpetrated, but what you have dared now is not susceptible to any pardon: it is an evil that is irremediable and incurable. For I am no longer acting through the prophets as intermediaries, but I have assumed the form of a servant, and I have lived among you as a man; and in spite of the frequency of my appeals and my exhortations, I have not persuaded you. This, in turn, is confirmed by the recital of the divine Gospels in these terms: “Jesus cried out, saying, ‘If anyone thirst, let him come to me and drink,’ and elsewhere: “Come to me, all you who labor and are heavy laden, and I will give you rest.” The divine Evangelists have let us know still many other declarations of this kind. In this way, then, the prophetic text has taught us that the total destruction that they undergo in the last place has been obtained for them by their folly against the Master. Then, in interrogative form again [he declares]: “Is not my hand strong to redeem? Or do I not have the strength to protect you [from danger]?” Do you think, he says, that the adversaries have conquered me because of my weakness? Is it not possible for anyone to see how easy and convenient it is for me to make you appear superior to everyone?

[AD 420] Jerome on Isaiah 50:3
Everything that is above us we call “heaven,” just as the winged things that are in the air are called “celestial” and the enemy powers are called “celestial” since they shuttle between heaven and earth.… Therefore, heaven is not covered up by a bag; but with the light of heaven closed off, the air that is underneath it becomes darkened with black clouds. We can interpret the heavens covered in darkness and concealed in a bag by saying that all are under sin and that the holy ones, too, need the mercy of God.

[AD 458] Theodoret of Cyrus on Isaiah 50:3
“I will clothe the sky with shadows, and I will change its cover to be like mourning cloth.” He has done this and will do it. For he did it when he was crucified: “From the sixth hour to the ninth the shadows covered the whole earth.” And he will do it again at the time of the fulfillment, for it says, “The sun will be darkened, and the moon will not give off its light.”

[AD 165] Justin Martyr on Isaiah 50:4
The power of his mighty word with which he always refuted the Pharisees and scribes, and indeed all the teachers of your race who disputed with him, was stopped like a full and mighty fountain whose waters have been suddenly shut off when he remained silent and would no longer answer his accusers before Pilate, as was recorded in the writings of the apostles, in order that those words of Isaiah might bear fruit in action: “The Lord gives me a tongue, that I may know when I ought to speak.” And his words, “You are my God, depart not from me,” teach us to put all our trust in God, the Creator of all things, and to seek aid and salvation from him alone; and not to imagine, as other [people] do, that we can attain salvation by means of birth, or wealth, or power or wisdom.

[AD 373] Ephrem the Syrian on Isaiah 50:4
“The Lord God has given me the tongue of the doctrine.” These words refer to Christ as well, who preached his new doctrine to all the peoples. And therefore all the peoples listened to it and were converted.

[AD 397] Ambrose of Milan on Isaiah 50:4
Now what ought we to learn before everything else, but to be silent that we may be able to speak? Lest my voice should condemn me before that of another acquits me, for it is written: “By your words you shall be condemned.” What need is there, then, that you should hasten to undergo the danger of condemnation by speaking when you can be more safe by keeping silent? How many have I seen to fall into sin by speaking, but scarcely one by keeping silent; and so it is more difficult to know how to keep silent than how to speak … a person is wise, then, who knows how to keep silent. Lastly, the Wisdom of God said, “The Lord has given to me the tongue of learning, that I should know when it is good to speak.” Justly, then, is one wise who has received of the Lord to know when he ought to speak. Wherefore the Scripture says well: “A wise person will keep silence until there is opportunity.”

[AD 420] Jerome on Isaiah 50:4-7
(Chapter 50—Verse 4 and following) The Lord has given me a learned tongue, so that I may sustain with words the weary. He awakens me morning by morning, awakens my ear as a master. The Lord God has opened my ear; I do not resist, I do not turn back. I offered my body to the ones striking me, and my cheeks to those plucking my beard. I did not turn my face away from those reproaching and spitting. The Lord God is ((added by the Vulgate)) my helper, therefore I am not ashamed; therefore I set my face like flint, and I know that I will not be put to shame. LXX: The Lord gives me the tongue of instruction, so that I may know when it is necessary for me to speak a word. He has set me in the morning, and added an ear to listen; and the instruction of the Lord opens my ears. But I do not refuse or contradict. I have given my back to the lashes, and my cheeks to the slaps. But I have not turned my face away from the shame of spitting. And the Lord is my helper, therefore I am not ashamed: but I have set my face like a mighty rock, and I know that I will not be put to shame. The Jews, separating this chapter from the previous ones, want to refer it to Isaiah, who says he received a word from the Lord about how to sustain and call back the weary and wandering people to salvation. And, in the manner of little children who are instructed in the morning hours, let him hear what the Holy Spirit says. And [let it be known] that he did not contradict His command, but when the Lord asked, 'Whom shall I send, and who will go to this people?' he answered, 'Here I am, send me' (Isaiah 6:8). And because it has been said: 'Listen to the word of the Lord, princes of Sodom: listen attentively to the law of our God, people of Gomorrah' (Isaiah 1:18), he endured so much hardship, not only the insults of words, but also the pains of wounds. However, he was not terrified by the conscience of the commanding God; but according to what is said in Ezekiel: 'Behold, I have made your face stronger than their faces, and your forehead harder than their foreheads, like adamant and flint I have made your face' (Ezekiel 3:8, 9), he crushed all their attacks. This they say, who by every means try to overturn the prophecies about Christ and distort them with a perverse interpretation, as if also these things were written about Isaiah, they could take away other testimonies about Christ that are so clear that they shed light on themselves for the eyes of everyone. Therefore, concerning the person of the Lord, in whom also the previous book ends, these things must also be mentioned: that, according to the arrangement of the assumed body, he was trained and acquired the language of learning, so that he would know when he should speak and when to be silent. Finally, he who was silent in his suffering now speaks through the Apostles and the men of the Apostolic age throughout the whole world. And it is a mark of great knowledge to give timely food to those under your care and to consider the individuality of your audience. Thus, the Apostle Paul, speaking by the testimony of his authorities, addresses those who do not accept the faith of the Prophets, saying: 'For we are indeed his offspring,' as some of your own poets have said, 'For we are indeed his offspring' (Acts 17:28), signifying Aratus. Again about the Comedian: Evil conversations corrupt good morals (1 Cor. XV, 33); and Epimenides' hexameter verse: Cretans are always liars, evil beasts, lazy gluttons (Titus I, 12). If they do not maintain the order and measure of the meters in translation, it should be known that in Greek they run with feet. However, he did this because he had learned the language of discipline, so that he would know when to speak a word. To this was added an ear through grace, which he did not have by nature: so that we understand that ears should not be received from the body, but from the mind, about which the Lord also spoke in the Gospel: He who has ears to hear, let him hear (Luke VIII, 8). The discipline and education that opened his ears, so that he might transmit the knowledge of the Father to us; who did not contradict him, but became obedient even unto death, and death on a cross (Philippians 2). So that he would offer his body or back to the blows; and his chest, capable of receiving the scourges of God, would not turn away from the blows. It is clear that he endured this from the minister of the chief priests: so that both the Jewish people and the priests would mock him. He who was struck and spat upon did not blush, but was led to the victim like a lamb; and like a sheep before the shearer, he did not open his mouth. But what the Son heard from the Father regarding the mystery of his assumed body, we learn more fully in the Gospel, where he himself says: And he who sent me, the Father, has given me a commandment, what I should say and what I should speak. And again: As I hear, I judge.

[AD 444] Cyril of Alexandria on Isaiah 50:4
[Ministers] who sing thankful hymns say that they have been given a tongue of discipline; that is, they are able to speak in a trained manner and expound the divine mysteries without fault and are able to speak fittingly to those who need words of encouragement.… On us the sun of righteousness has arisen and has shed its light on our mind so that we are and are known as children of light and of the day. For we, having faith in Christ, are enriched with illumination from him; that is, we have our hearing enhanced and are thus enabled to hear.

[AD 458] Theodoret of Cyrus on Isaiah 50:4
Christ our Master says this in a human way. For the rest, we find many statements of this kind in the divine Gospels: “And Jesus increased in age,” it is said, “and wisdom and grace before God and before people.” He calls youth “early”; thus, the prophet likewise taught this in a preceding passage. After having announced [Christ’s] conception by the Virgin, he had added, “Before he [the child] shall know good or evil, he refuses evil, to choose the good.” The Evangelist declares something similar: “And the child grew and became strong in spirit, filled with wisdom; and the grace of God was on him.” As for the phrase “the instruction the Lord gives opens my ears,” in my opinion, it is not pronounced regarding him but on the subject of the disciples who believed in [Christ], for he gives the name of “ears” to his hearers, that is, to those to whom he presents the divine words, that is, to those to whom he declared, as we learn it in reading the holy Gospels: “He who has ears to hear, let him hear!”

[AD 373] Athanasius of Alexandria on Isaiah 50:6
And being by nature intangible, the Word yet said, “I gave my back to the stripes, and my cheeks to blows, and I hid not my face from shame and spitting.” For what the human body of the Word suffered, this the Word, dwelling in the body, ascribed to himself, in order that we might be enabled to be partakers of God the Word. Truly it is a mystery that it was he who suffered, and yet suffered not. He suffered, because his own body suffered, and he was in it, which thus suffered. He suffered not, because the Word, being by nature God, is impassible. And while he, the incorporeal, was in the passible body, the Body had in it the impassible Word, which was destroying the infirmities inherent in the body.

[AD 373] Athanasius of Alexandria on Isaiah 50:6
Our Lord and Savior Jesus Christ comes before us, when he would show [people] how to suffer, who when he was struck bore it patiently, being reviled he reviled not again, when he suffered he threatened not, but he gave his back to the smiters and his cheeks to buffetings, and he turned not his face from spitting; and at last, he was willingly led to death, that we might behold in him the image of all that is virtuous and immortal, and that we, conducting ourselves after these examples, might truly tread on serpents and scorpions and on all the power of the enemy.

[AD 379] Basil of Caesarea on Isaiah 50:6
If you remain unruffled, you silence your insolent assailant by giving him a practical illustration of self-control. Were you struck? So also was the Lord. Were you spat on? The Lord also suffered this, for “he did not turn his face from the shame of the spittle.” … You have not been condemned to death or crucified.

[AD 386] Cyril of Jerusalem on Isaiah 50:6
[This is] as though he were to say, “Though I knew beforehand that they would strike me, I did not even turn aside my cheek; for how could I have nerved my disciples to undergo death for the truth if I had been afraid?”

[AD 391] Macarius of Egypt on Isaiah 50:6
Now if God willed to accept and to lower Himself to such sufferings, dishonours, and humiliations, then no matter how much you humble yourself, you whose nature is mud and subject to death, you will never resemble your Lord [in this]. God for your sake humbled Himself, but you, for your own sake, do not humble yourself. You are proud and puffed up. God came and took up your burden to give you His rest, but you do not wish to endure labours and suffering. By your labours your wounds are healed.

[AD 420] Jerome on Isaiah 50:6
The Jews, separating this chapter from what has been said previously, wish to refer it to the person of Isaiah, in that he would say that he received the word from the Lord and how he put up with a lazy and wandering people and called them back to salvation, and in the manner of small children who are trained early in the morning, Isaiah recited what he heard from the Holy Spirit.… But these verses should be applied to the person of the Lord in which the older book is fulfilled, since according to the dispensation of the flesh that Christ assumed, he was trained and accepted the lash of discipline so that he would know when he ought to speak and when to keep quiet. And he who in his passion was silent, through the apostles and apostolic people speaks throughout the whole world.To Christ was added through the grace of the ear things that he did not have by nature, that we might understand that we ought to accept with the ears not of our body but of the mind.… The breast that contained God was beaten.… This discipline and training opened his ears that he was able to communicate the knowledge of the Father to us.… We learned more fully in the gospel that the Son, according to the flesh he took on, spoke the mystery that he had heard from the Father.

[AD 458] Theodoret of Cyrus on Isaiah 50:6
This whole recital is taught by the holy Gospels. For the servant of the high priest gave [Christ] a blow on the cheek; some struck his face, saying, “Prophesy to us, Christ! Who is the one who struck you?” Others spat in his face; as for Pilate, he had him scourged and delivered him to be crucified. So, all this he predicts in the prophecy to teach of his own patience.

[AD 407] John Chrysostom on Isaiah 50:7
For the railings, and insults, and reproaches and gibes inflicted by enemies and their plots are compared with a worn-out garment and moth-eaten wool when God says, “Do not fear the reproach of people, neither be afraid of their revilings, for they shall grow old as does a garment, and like moth-eaten wool so shall they be consumed.” Therefore, let none of these things that are happening trouble [you], but stop asking for the aid of this or that person and running after shadows (for such are human alliances); persistently call on Jesus, whom [you serve] … and in a moment of time all these evils will be dissolved.

[AD 444] Cyril of Alexandria on Isaiah 50:7
And the Father was Christ’s helper. For he did not allow or concede that his own Son should be completely shamed or overwhelmed. For they were punished, those who sought to take their punishment out on me as those who dare to fight with God.… For though being with us, he was the only-begotten Word of God. He put on an identical human likeness, by which reason alone he was believed to be of a nature with us. For every human being is subject to faults and sins, and no one alive is completely blameless. He alone in becoming man retained the divine dignity.… And being Word and God, his flesh was able to shoo away destruction. Thus, the Son became a man who was fit to be accepted by the Father. For all that human beings have is God-given. For the one God and Father, through him, undid the power of death through his resurrection from the dead.… He was the servant of God, who while being human was yet truly the Son of God and the Father. And to hear his voice means no transgression of the law but a confirming of the law through types and shadows discerning the truth which is Christ and the prophecies of him, as Paul notes. … His voice is the evangelical and divine preaching that calls us to the redemption that is through faith in Christ. He also calls us to a proper behavior that lives in a way that is, by far, more consistent than the way of the law. The law was given in the shadows. Faith was given in the bright and shining light.

[AD 420] Jerome on Isaiah 50:8-9
(Verse 8, 9.) He is near who justifies me: who will contradict me? Let us stand together. Who is my adversary? Let him come near to me. Behold, the Lord God is my helper: who is he that will condemn me? Behold, all of them shall wear out like a garment, the moth shall eat them up. LXX: He is near who justifies me: who is he that will judge me, stand up against me together? And who is he that will enter into judgment with me? Let him come near to me. Behold, the Lord is my helper, who shall afflict me? Behold, all of you shall grow old like a garment, and like a moth shall eat you. If anyone, says He, thinks that I am justly addicted to the cross and have committed some sin, let him resist me. Who is there to be judged with me, so as not to be overcome by the power of my majesty, but by reason? However, he is judged with the Lord, not by the authority of the reigning, but by the comparison of virtues: just as the apostles judged the twelve tribes of Israel, and the Ninevites, and the queen of Sheba judged the people of the Jews. According to which sense, it is said to Jerusalem: Sodom is justified by you (Ezech. XVI, 52). Therefore, since no one can be justified in the presence of the Lord, all will grow old like a garment (Ps. CI). And what grows old is close to ruin. And it will consume them like a moth, it says. Clearly the conscience of sinners; and the zeal of the saved gentiles. About which it is said at the end of this volume: Their worm will not die. And in Micah against perverse princes: I will take away their goods like a moth devouring, and walking on the standard on the day of speculation (Micah VII, 4, sec. LXX). And in Proverbs: The moth of bones has understanding of the heart (Prov. XIV, 30, sec. LXX). For tinea, in this place Symmachus interpreted it as rust: while Aquila as worm.

[AD 215] Clement of Alexandria on Isaiah 50:9
There is a person who runs down birth, describing it as subject to decay and death, who forces things and suggests that the Savior was speaking about having children in saying that we should not store treasure on earth, where it grows rusty and moth-eaten. And [this person] is not ashamed to set alongside these the prophet’s words: “You shall all grow old like clothes, and the moth will feed on you.” We do not contradict Scripture. Our bodies are subject to decay and are naturally unstable. Perhaps he might be prophesying decay to his audience because they were sinners. The Savior was not speaking about having children. He was encouraging sharing of resources in those who wanted only to amass vast amounts of wealth rather than offer help to those in need.

[AD 458] Theodoret of Cyrus on Isaiah 50:9
“Behold, you will all like a garment grow old, and something like a worm will devour you.” The parable is accurate, for the worm that comes from the clothes destroys them, and sin, which is born from us, ruins those who allow it to grow.

[AD 528] Procopius of Gaza on Isaiah 50:9
Isaiah also gives the name “moth” to those who devour their conscience in their recklessness.… It might be said that the moths are their sins, which worm their way in among those they inhabit, like moths devouring clothing for food. An attitude that inclines toward having no fear is indicative of a people on their way to this kind of ruin, yet who think they are indestructible. But punishment also clearly awaits them. They will be utterly consumed by misfortune as by a moth.

[AD 220] Tertullian on Isaiah 50:10
By the mouth of Isaiah also [God] has asked concerning him, “Who is there among you that hears God? Let him hear the voice of his Son.” When, therefore, he here presents him with the words, “This is my beloved Son,” this clause is of course understood, “who I have promised.” For if he once promised and afterwards says, “This is he,” it is suitable conduct for one who accomplishes his purpose that he should utter his voice in proof of the promise that he had formerly made; but unsuitable in one who is amenable to the retort, “Can you, indeed, have a right to say, ‘This is my son,’ concerning whom you have given us no previous information, any more than you have favored us with a revelation about your own prior existence?”

[AD 420] Jerome on Isaiah 50:10-11
(Verse 10, 11.) Who among you fears the Lord, and listens to the voice of his servant? Who walks in darkness, and has no light? Let him trust in the name of the Lord, and rely on his God. LXX: Who among you fears the Lord, and listens to the voice of his servant? Who walks in darkness, and has no light? Let him trust in the name of the Lord, and rely on his God. You have struck me, you have spat on my face: yet I call my persecutors to repentance. For I do not desire the death of a sinner, but only that he should turn back and live (Ezek. 33). And I say: who among you fears the Lord, and listens to the voice of his servant or his child, that is, his Son? of whom one is assumed flesh, the other is of nature. And indeed, let us not think it is enough to fear the Lord, according to what is said in Proverbs: The fear of the Lord is the beginning of wisdom (Prov. 9:10). For perfect love casts out fear, because fear involves punishment. But whoever fears is not perfect in charity. But this fear is placed for timidity and caution; about which we read elsewhere: Blessed is the one who fears everything (Prov. 20), because of caution, that is, because of timidity: those who are commonly called timid in the religion of God. For the Lord protects their path; and guards the way of the timid. Regarding this fear it is written: The fear of the Lord conquers all things. And elsewhere: There is no lack for those who fear Him (Sirach 25:14; Psalm 34:10). Finally, after many steps of virtue, one arrives at this kind of fear of the Lord. For the divine word speaks in the person of a master and father, instructing the disciple and son: If you call upon wisdom and give your voice to understanding, and if you seek it like money and search for it like treasures, then you will understand the fear of the Lord, and you will find the knowledge of God (Prov. 2:3). This is the fear that preserves the souls of the holy ones intact, chaste, and pure, of which it is said, The fear of the Lord remains forever (Ps. 19:9). To whom the divine scriptures exhort us: Fear the Lord, and give him glory (Apoc. XIV, 7). Therefore, whoever fears the Lord in this way, let him listen to the voice of his servant or his child, who walked in darkness and had no light; who had no appearance or glory, but in the likeness of sinful flesh took on the form of a servant, that he might overcome sin in the flesh. Concerning this, it is said, let him hope in the name of the Lord, and rely on his God: so that whatever belongs to human frailty, may be strengthened and sustained by divine majesty. This is in accordance with the Hebrew. However, according to the Septuagint, it is said about sinners, who refused to obey the voice of His Son, and they walk in the darkness of error, and therefore they do not have light. For it was not possible for wisdom to enter into a perverse soul. They did not know or understand, and therefore they walk in darkness. For they did not do the works of the Lord and His commandments, nor did they sow righteousness for themselves, nor did they harvest the vine in order to kindle the light of knowledge for themselves. For whoever desires wisdom, let them keep the commandments, and the Lord will give it to them. Thus it is said to God: Your commandments are a light. And elsewhere: The commandment of the Lord is clear, enlightening the eyes (Ps. 19:9). And it is commanded to the wicked to trust in the Lord, and those who fall into sin rely on his help and support.

[AD 458] Theodoret of Cyrus on Isaiah 50:10
It is as a man that he calls himself “Servant,” for “although he exists in the form of God, he has assumed the form of a servant.” Likewise in the divine Gospel [Christ] says that he has received instruction as to what he should say and proclaim. “They walk in darkness, and there is no light for them.” Although the light has risen, as for them, they have clung to the darkness. “Trust in the name of the Lord, and rely on God.” [Isaiah] says, if you really put absolute and true hope in God, that will [serve to] sustain you and make you sure.

[AD 253] Origen of Alexandria on Isaiah 50:11
If then this is the character of the body that rises from the dead, let us now see what is the meaning of the threatened “eternal fire.” Now we find in the prophet Isaiah that the fire by which each person is punished is described as belonging to himself. For it says, “Walk in the light of your fire and in the flame which you have kindled for yourselves.” These words seem to indicate that every sinner kindles for himself the flame of his own fire and is not plunged into a fire that has been previously kindled by someone else or that existed before him.

[AD 253] Origen of Alexandria on Isaiah 50:11
This “fire” is not “from the altar.” The fire that is “from the altar” is the fire of the Lord. But that which is outside the altar is not of the Lord but is properly of each one who sins.… This fire is of those who have ignited it, just as it also was written in other places, “Walk in your fire and in the flame which you kindled for yourselves.” But to Isaiah his own fire was not applied but the fire of the altar that “will cleanse his lips.”

[AD 390] Gregory of Nazianzus on Isaiah 50:11
One light alone let us shun: that which is the offspring of the terrible fire. Let us not walk in the light of our own fire and in the very flame we have kindled. For I know of a cleansing fire that Christ came to send on the earth, and that he himself is anagogically called a fire. This Fire takes away whatever is material and of evil habit. This he desires to kindle with all speed, for he longs for speed in doing us good, since he gives us even coals of fire to help us. I know also a fire that is not cleansing but avenging; either that fire of Sodom, which he pours down on all sinners, mingled with brimstone and storms, or that which is prepared for the devil and his angels.

[AD 420] Jerome on Isaiah 50:11
(Verse 11) Behold, all of you who kindle fire, girded with flames, walk in the light of your fire, and in the flames that you have kindled: it is made by my hand, you will sleep in sorrows. LXX: Behold, all of you who kindle fire, and strengthen the flame; walk in the light of your fire, and in the flame that you have kindled; these things have been made for you because of me. You will sleep in mourning. Exhortation is useless, and there is no hope of salvation after wicked deeds. All have turned aside, together they have become useless; there is none who does good, there is not even one (Psalm 14:3); all light their own fire and prepare their own torches. For they are like a bundle of dry grass, wood, straw, thorns, and thistles, which will be consumed by eternal fire. Hence it is also written in Proverbs: Fire thrives where there are many logs (Proverbs 26:20). But if a small spark can ignite a large material, how much destruction can a great flame cause? It is also said in the Letter to the Hebrews, concerning the land which produces thorns and thistles, that it is worthless, cursed, and its end is to be burned (Hebrews 6:8). Therefore, those who are girded with flames and surrounded, and have made the fire strong in themselves, are provoked to salvation, and it is said to them: Walk in the light of your fire; and in the flames that you have ignited, so that they may learn the power of God in punishment and suffering, and return to salvation. However, it signifies the devastation of the Jewish people, who were handed over to the Romans, and who continue to bear the yoke of captivity. For all these things have been done by the hand of Christ, and they will sleep in sadness and sorrow; because they did not want to receive the Son of God with either kindness or torment. He speaks to them, saying: Go into the eternal fire, which has been prepared for the devil and his angels (Matt. 25:41). This is also what the Apostle says: Wrath has come upon you to the end (1 Thess. 2:16). In this chapter, we learn that according to the quality of sin, each person kindles a fire for themselves. And just as in the same location, and if it can be said, in the same bed, some are healthy while others are burning with the heat of fever, feeling different torments due to the diversity of bodily fluids and phlegm: so the fire that is kindled by sinners has its material in sins and iniquity, of which it is written: Evil will burn like a fire, and like dry grass it will be consumed by fire (Isaiah 9:18).
