1 The sin of Judah is written with a pen of iron, and with the point of a diamond: it is graven upon the table of their heart, and upon the horns of your altars; 2 Whilst their children remember their altars and their groves by the green trees upon the high hills. 3 O my mountain in the field, I will give thy substance and all thy treasures to the spoil, and thy high places for sin, throughout all thy borders. 4 And thou, even thyself, shalt discontinue from thine heritage that I gave thee; and I will cause thee to serve thine enemies in the land which thou knowest not: for ye have kindled a fire in mine anger, which shall burn for ever. 5 Thus saith the LORD; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD. 6 For he shall be like the heath in the desert, and shall not see when good cometh; but shall inhabit the parched places in the wilderness, in a salt land and not inhabited. 7 Blessed is the man that trusteth in the LORD, and whose hope the LORD is. 8 For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit. 9 The heart is deceitful above all things, and desperately wicked: who can know it? 10 I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings. 11 As the partridge sitteth on eggs, and hatcheth them not; so he that getteth riches, and not by right, shall leave them in the midst of his days, and at his end shall be a fool. 12 A glorious high throne from the beginning is the place of our sanctuary. 13 O LORD, the hope of Israel, all that forsake thee shall be ashamed, and they that depart from me shall be written in the earth, because they have forsaken the LORD, the fountain of living waters. 14 Heal me, O LORD, and I shall be healed; save me, and I shall be saved: for thou art my praise. 15 Behold, they say unto me, Where is the word of the LORD? let it come now. 16 As for me, I have not hastened from being a pastor to follow thee: neither have I desired the woeful day; thou knowest: that which came out of my lips was right before thee. 17 Be not a terror unto me: thou art my hope in the day of evil. 18 Let them be confounded that persecute me, but let not me be confounded: let them be dismayed, but let not me be dismayed: bring upon them the day of evil, and destroy them with double destruction. 19 Thus said the LORD unto me; Go and stand in the gate of the children of the people, whereby the kings of Judah come in, and by the which they go out, and in all the gates of Jerusalem; 20 And say unto them, Hear ye the word of the LORD, ye kings of Judah, and all Judah, and all the inhabitants of Jerusalem, that enter in by these gates: 21 Thus saith the LORD; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem; 22 Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers. 23 But they obeyed not, neither inclined their ear, but made their neck stiff, that they might not hear, nor receive instruction. 24 And it shall come to pass, if ye diligently hearken unto me, saith the LORD, to bring in no burden through the gates of this city on the sabbath day, but hallow the sabbath day, to do no work therein; 25 Then shall there enter into the gates of this city kings and princes sitting upon the throne of David, riding in chariots and on horses, they, and their princes, the men of Judah, and the inhabitants of Jerusalem: and this city shall remain for ever. 26 And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and meat offerings, and incense, and bringing sacrifices of praise, unto the house of the LORD. 27 But if ye will not hearken unto me to hallow the sabbath day, and not to bear a burden, even entering in at the gates of Jerusalem on the sabbath day; then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched.
[AD 420] Jerome on Jeremiah 17:1
(Chapter 17, Verse 1) The sin of Judah is written with an iron pen, engraved with an adamantium nail, upon the width (or height) of their hearts (or in the depth of their hearts), and upon the horns of their altars (or thrones). Concerning the nations that have turned to the Lord, it has been said: Behold, I will show them in turn, I will show them my hand and my power. Now, speaking of Israel who is rejected: The sin of Judah is written with an iron pen, engraved with an adamantium nail, and so on. Why the Septuagint has been omitted, I do not know; unless perhaps they spared their own people: just as it is clear in Isaiah that they did so: Cease from man, whose breath is in his nostrils; for why should he be esteemed? (Isaiah 2:22); and many similar things, which if I wanted to arrange them all, it would not be a book, but books. Because his mercy is confirmed upon us, and the truth of the Lord remains forever (Psalm 116, 1, 2). And concerning those whom he said to Moses: Let me alone, that I may destroy this people, and make you into a great nation (Exodus 32, 10). But the sin of the Jews is indelible, and, so to speak, cannot be abolished by any means; it is written with an iron stylus on an adamant nail, which in Hebrew is called Samir (); not that there is any nail that is called Samir; but that the adamant stone (which has received this name because it is untamable and unbreakable) has such brilliance and lightness that it can be written on without any impediment with an iron stylus: so that the hard material of iron may write on the harder adamant tablet, and what is written may endure forever. For they themselves said: 'His blood be upon us and upon our children' (Matthew 27). Therefore, it has been written or engraved on the horns of their altars or shrines, so that sacrilegious works may be remembered forever. But if this is the case, where is that which an old woman madly fabricates, that a person can be without sin if they wish, and that God's commandments are easy?

[AD 458] Theodoret of Cyrus on Jeremiah 17:1
Nothing is more potent than the conscience: letters inscribed on it are indelible. I mean, even if everyone mounted a case to his or her conscience supported by favorable evidence, the conscience itself cannot tolerate the wickedness of falsehood. It is pricked and goaded and delivers its verdict incorruptibly. He says this here, too: The facts accuse you, and the conscience joins in testimony against you. He reminds them also of the groves, the altars and what was done on them, and he threatens to give to the enemy all their wealth along with the idols.

[AD 420] Jerome on Jeremiah 17:2-3
(Verse 2, 3.) When their sons remember their altars, and the groves of trees and leafy branches on the high mountains, sacrificing in the field, I will give your strength and all your treasures to plunder. Your lofty places will be destroyed because of your sins in all your borders. And you will be left alone in the inheritance that I gave you, and I will make your enemies serve you in a land that you do not know, because you kindled the fire in my anger, and it will burn forever. And these are not found in the Septuagint, for the same reason (as I believe) that we have mentioned above, namely, lest the eternal sentence should remain against them. 'You shall be left,' He says, 'alone from your inheritance, which I gave you, and I will make you serve your enemies in a land which you do not know, either under the Babylonians or, as is more accurate, under the Romans. For they themselves have kindled the fire and provoked the most merciful Lord to anger, whose fire of fury will burn forever.' I am ashamed of our argument, which disputes the truth of the Hebrews. The Jews read against themselves, and the Church does not know what is in their favor. Thus, we, who are the sons of the Apostles, remember the injustices of the previous people and testify that they suffered justly. However, the high places, which are called Bamoth in Hebrew, can also be understood as a reference to the heretics who have exalted themselves, and their language has spread throughout the land. Those who have burst forth into such great madness, that they have remained alone without the grace of the Holy Spirit, and have lost the inheritance of the Lord, namely the prior truth of faith. Hence, eternal fire is prepared for them, and the servitude of demons, who are enemies and avengers.

[AD 253] Origen of Alexandria on Jeremiah 17:5
From this statement we will refute those who suppose that the Savior was a man but not also the Son of God. For they dared with many human evils to say even this, that the Only-begotten, the firstborn of all creation, could not be God. For “cursed is one who has hope in humankind.” It is evident that cursed are those who have hope in humankind. I may say that I do not have hope in people.

[AD 420] Jerome on Jeremiah 17:5-6
(Verses 5, 6.) Thus says the Lord: Cursed is the man who trusts (or has hope) in man, and relies on flesh for his strength, and turns his heart away from the Lord. He will be like a shrub in the desert, and will not see when good comes; but he will live in dryness in the desert, in a land of salt and uninhabitable. If every man is cursed who trusts in man, then Paul of Samosata and Photinus, although they proclaim the Savior as holy and surpassing all virtues, still confess him as a man; therefore, they will be cursed for having hope in man. But if it is opposed to us, that we also believe in him who says: Now you seek to kill me, a man who has spoken the truth to you, which I have heard from God, Abraham did not do this: you do the works of your father. (John 8:40) We will respond with that of the Apostles: And if we have known Christ according to the flesh at some time, but now we no longer know him. Finally, the same Apostle writes in the beginning of his letter to the Galatians: Paul, an Apostle, not from men, nor through man, but through Jesus Christ, and God the Father, who raised him from the dead, and who are with me all the brethren. (Galatians 1:1-2). For if death was swallowed up in victory (Hosea 13), why did not the lowliness of the flesh, which was assumed for the salvation of mankind, pass into the majesty of divinity, so that it might make both one; and we do not worship the creature, but the Creator, who is blessed forever? Therefore, he is cursed, not only who has hope in man, but who puts his trust in the flesh, that is, his own strength, and whatever he accomplishes, considers it to be not of the mercy of the Lord, but of his own power. For whoever does this, departs from the heart of the Lord, asserting that he can do what he cannot. And he will be like myrtle, which in Hebrew is called Aroer, or as Symmachus interpreted, a fruitless tree in the desert. And he will not see the good things that the multitude of nations will see when they come, but he will dwell in dryness in the desert. This is said of the people of Judah who dwell in the desert, do not bear fruit, and live in a land of salt, which produces no fruit, and is uninhabitable, having no guest of God, nor the protection of angels, nor the grace of the Holy Spirit, nor the knowledge of teachers.

[AD 430] Augustine of Hippo on Jeremiah 17:5
“What is your own opinion? What people do you call happy?” He [the psalmist] would not say, “Happy is the people whose strength is in their own mind.” If he had said this, he would, it is true, distinguish that people from the former that made happiness consist in that visible and bodily good fortune, but he would not yet have passed beyond all the vanities and lying follies, for the same Scriptures teach elsewhere: “Cursed be everyone that places his hope in humankind.” Therefore, he ought not to place it in himself, because he himself is human. Thus, in order to pass beyond the boundaries of all vanities and lying follies and to place happiness where it truly exists, he says, “Happy is the people whose God is the Lord.”

[AD 430] Augustine of Hippo on Jeremiah 17:5
The Stoics, when questioned about where they place the efficient cause of the happy life that is the thing in people that makes life happy, answer that it is not bodily pleasure but a virtuous mind. What says the apostle? Does he agree? If he agrees, let us agree, too. But he does not agree, because Scripture reproves those who trust in their own virtue. And so the Epicurean who places a person’s supreme good in the body is placing his hopes in himself. But after all, the Stoic who places a person’s supreme good in the mind has indeed placed it in a person’s better part. But even he has placed it in himself. Now the Stoic is a human just as much as the Epicurean. Cursed therefore is everyone who places his hope in humankind. So what now? Here we have three people set before our eyes: an Epicurean, a Stoic, a Christian. Let us question them one by one. “Tell us, Epicurean, what thing makes one blessed?” “Bodily pleasure,” he replies. “Tell us, Stoic.” “A virtuous mind.” “Tell us, Christian.” “The gift of God.”

[AD 430] Augustine of Hippo on Jeremiah 17:5
But of these matters, all of which are true objects of faith, those only pertain to hope that are embraced in the Lord’s Prayer. For “cursed is the one that trusts in humankind” is the testimony of Holy Scripture. Consequently, this curse attaches also to the person who trusts in himself. Therefore, we ought to ask for nothing that we either hope to do well or hope to obtain as a reward for our good works except from God the Lord.

[AD 430] Augustine of Hippo on Jeremiah 17:5
Out of that confession of faith that is briefly contained in the creed and that, pondered according to the flesh, is the milk of babes but spiritually considered and studied is the food of the strong, arises the good hope of believers, which holy charity accompanies. But of all those things that are to be believed by faith, only those pertain to hope that are contained in the Lord’s Prayer. For “cursed is everyone who puts hope in humankind,” as the divine Scriptures testify; and, consequently, one who puts hope in himself is also ensnared in the chain of this curse. Therefore, we ought to make petition only of the Lord God, whatever it is that we hope to do well or to obtain as a reward for good works.

[AD 430] Augustine of Hippo on Jeremiah 17:5
Blessed are all who trust in God. If the blessed are those who trust in him, then the wretched are those who trust in themselves. Cursed, you see, is everyone who puts his hopes in humankind, so do not put them even in yourself, because you too are human. If you put your hopes in another person, that is the wrong kind of humility. But if you put your hopes in yourself, that is dangerous pride. What is the difference, anyway? Each is pernicious, neither is to be chosen. Humble in the wrong way, you cannot lift yourself up; dangerously proud, you are heading for a fall.

[AD 430] Augustine of Hippo on Jeremiah 17:5
Take care not to let trust in your own strength steal on you, for you are human, and “cursed is everyone who puts his hope in humankind.” But put your trust fully and with your whole heart in God, and he will be your strength. Trust him lovingly and gratefully and say to him humbly and faithfully, “Trust in the Lord with your whole heart; he will be your strength.”

[AD 430] Augustine of Hippo on Jeremiah 17:5
People who despise being in need before God, lest they receive true perseverance from him, glory in their own false endurance and seek to “confound the counsel of the poor, because the Lord is his hope.” Nor do they regard, seeing they are human and attribute so much to their own, that is, to the human will, that they run into that which is written, “Cursed is everyone who puts his hope in humankind.”

[AD 379] Basil of Caesarea on Jeremiah 17:6-7
A person who relies on himself, however, or even on the person whose duty it is to provide for his needs, and thinks that his own activity or that of his associate is a sufficient resource for his livelihood runs the risk, as he places his hope in humankind, of falling under the curse that reads, “Cursed is the one that trusts in humankind and makes flesh his arm and whose soul departs from the Lord.” Now, by the words “that trusts in humankind” the Scripture forbids a person to place his hope in another, and by the words “and makes flesh his arm” it forbids him to trust in himself. Either course is termed a defection from the Lord. Further, in adding the final issue of both, “He shall be like tamarisk in the desert, and he shall not see when good shall come,” the Scripture declares that for anyone to place his trust either in himself or in anyone else is to alienate himself from the Lord.

[AD 379] Basil of Caesarea on Jeremiah 17:6-7
One thing you must flee, sin. One refuge from evil must be sought, God. Do not trust in princes. Do not be exalted in the uncertainty of wealth. Do not be proud of bodily strength. Do not pursue the splendor of human glory. None of these things save you. All are transient. All are deceptive. There is one refuge: God. “Cursed is the one who trusts in humankind” or in any human thing.

[AD 379] Basil of Caesarea on Jeremiah 17:6-7
One who puts his trust in humankind or is buoyed up by some other concerns of life, such as power or possessions or any of the things considered by the many to be glorious, is not able to say, “O Lord my God, in you have I put my trust.” In fact, there is a command that we should not put our trust in rulers, and “cursed is the one who trusts in humankind.” As it is proper not to worship anything else besides God, so also is it proper not to trust in any other except God the Lord of all things. “The Lord,” it is said, “is my hope and my praise.”

[AD 420] Jerome on Jeremiah 17:6-7
It is not only the one who puts his hope in humankind that is accursed, but also the one who uses the flesh of his arm, that is, his strength and all that he does, not for the Lord of mercy but so that power will be thought to have come from him. For whoever does this withdraws his heart from the Lord by claiming himself to be capable when he is not capable. He will also be like the tamarisk in the desert, which, in Hebrew, is called an aroher, or, as translated by Symmacus, a fruitless plant, nor will he see goodness when it arrives and is seen by the multitude of nations, but he will live in a wasteland. All this is said about the Jewish people, who live in a desert and do not bear fruit and are located in an uninhabited salt land that produces no fruit and is a host neither to God, nor to the army of angels, nor to the grace of the Holy Spirit nor to the knowledge of teachers.

[AD 430] Augustine of Hippo on Jeremiah 17:6-7
It is said, “It is by his own fault that anyone deserts the faith, when he yields and consents to the temptation that is the cause of his desertion of the faith.” Who denies it? Because of this, perseverance in the faith is to be said to be a gift of God. For a person daily asks for this when he says, “Lead us not into temptation.” If he is heard, it is this that he receives. Thus, as he daily asks for perseverance, he assuredly places the hope of his perseverance not in himself but in God. I, however, am loath to exaggerate the case with my words, but I rather leave it to them to consider and see what it is of which they have persuaded themselves—“that by the preaching of predestination, more despair than exhortation is impressed on the hearers.” For this is to say that a person then despairs of his salvation when he has learned to place his hope not in himself but in God, although the prophet cries, “Cursed is one who has his hope in humankind.”

[AD 430] Augustine of Hippo on Jeremiah 17:6-7
We must find out from what source true perseverance, worthy of the name, is to be had. There are those who attribute it to the powers of human will, not those that people have from divine assistance, but from their own free will. But that is an arrogant error. It is the error of the rich about whom the psalm speaks: “a reproach to the rich, and contempt to the proud.” Glorying in their own false endurance, they wish “to confound the counsel of the poor person, but the Lord is his hope.” Since they are people and attribute so much to themselves, that is, to their human will, they do not tend to apply to themselves the words of Scripture: “Cursed is everyone who trusts in humankind.”

[AD 430] Augustine of Hippo on Jeremiah 17:6-7
This is the combat we are challenged to, this the struggle with the flesh, this the struggle with the devil, this the struggle with the world. But let us be wary of confidence, because the one who instituted this contest does not watch his own champions, nor does he encourage us to rely on our own strength. Anyone relying on his own strength, you see, is relying, being clearly human, on the strength of a person; and accursed is everyone who rests his hope in humankind.

[AD 430] Augustine of Hippo on Jeremiah 17:6-7
We have recognized ourselves, seen ourselves and taken a thorough look at ourselves. Let us groan and sigh in ourselves, pour out prayers, that we enter not into temptations. We must not rely on our own powers to overcome all these things. Blessed, after all, is the one whose helper is the God of Jacob, his hope in the Lord his God, not in himself, because he is a mere mortal. But cursed is everyone who places his hope in humankind.

[AD 430] Augustine of Hippo on Jeremiah 17:6-7
In order that we fall not away from the virtue of the soul, we ought to watch especially against those snares of the suggestions of the devil that we presume not of our own strength. For “cursed is everyone who places his hope in humankind.” And who is he, but mortal? We cannot therefore truly say that the person who places his hope in humankind places it in himself. For this also is to “live after humankind,” what is it but to “live after the flesh”? Whoever therefore is tempted by such a suggestion, let him hear, and if he has any Christian feeling, let him tremble. Let him hear, I say, “If you live after the flesh, you shall die.”

[AD 735] Bede on Jeremiah 17:6-7
But let us see what kind of fruits a bad tree produces, and let us avoid bearing such fruits. The prophet Jeremiah says, “Cursed is the one who puts his trust in human beings and makes his flesh his support, and whose heart turns away from the Lord; such a person will be like a tamarisk in the desert.”

[AD 220] Tertullian on Jeremiah 17:7-8
For as it says in the psalm, “Those who sow in tears shall reap with shouts of joy,” so also in the gospel, those who sow in laughter, that is, because of joy, shall reap in tears. Long ago did the Creator set these things side by side: Christ, by not changing them but only giving them emphasis, has made them new. “Woe to you, when all people speak well of you.” That is what their ancestors used to do to the false prophets. No less does the Creator, by Isaiah, censure those who seek after the blessing and praise of people: “My people, those who call you blessed, lead you astray and upset the paths of your feet.” And in other terms he even forbids them to have any confidence in a person, and consequently not in human praise, as by Jeremiah, “Cursed is the one who trusts in humankind.”

[AD 258] Novatian on Jeremiah 17:7-8
If Christ is only man, how is he present wherever he is invoked—since it is not people’s nature but God’s to be able to be present everywhere? If Christ is only man, why is a man called on in prayer as a mediator, when calling on a mortal to grant salvation is considered useless? If Christ is only man, why is hope put in him, when hope in humankind is declared to be accursed? If Christ is only man, why cannot he be denied without ruin to one’s soul, when it is declared that an offense against people can be forgiven? If Christ is only man, how does John the Baptist bear witness of him when he says, “He who comes after me was made before me, for he was before me”? If Christ were only man, then, being born after John, he could not be before John, unless he preceded him as God.

[AD 258] Cyprian on Jeremiah 17:7-8
Let no one deceive himself. Let none be misled. Only the Lord can grant mercy. Sins committed against him can be cancelled by him alone who bore our sins and suffered for us, by him whom God delivered up for our sins. People cannot be above God, nor can the servant by any indulgence of his own remit or condone the graver sort of crime committed against his Lord, for that would make the apostate liable to this further charge, he knows not the words of the prophet: “Cursed is the one who puts his hope in humankind.” It is our Lord we must pray to, it is our Lord we must win over by our penitence. For he has said he will deny the person who denies him, and he alone has received all power of judgment from his Father.

[AD 386] Cyril of Jerusalem on Jeremiah 17:7-8
He said to him, “Yes, sir. The long duration of my illness makes me desire health. But, desire it as I may, I have no one.” Do not lose heart, my good fellow, because you “have no one.” You have God standing by you. One who is at once man and God under different aspects, for both must be confessed. The confession of the humanity without the confession of the divinity is unavailing, or rather earns a curse. For “cursed is one who puts his trust in humankind.”

[AD 420] Jerome on Jeremiah 17:7-8
It may be said both of the Jews and of the heretics that they put their hope in humankind, for the messiah whom they believe to be coming is clearly not the Son of God but a mere man. The person of the church, in contrast, who puts faith in the Lord, hears this: “Know that the Lord himself is God.” Because he trusts in the Lord, he will be compared with a tree and will be the one of whom the first psalm sings: “He is like a tree that is planted by flowing waters, bearing its fruit in season; and its leaf does not wither.” Being transplanted on (or by) the waters refers to the various graces of the Holy Spirit. And sending its roots into the water (or by the stream) means that one receives abundance from the Lord. But we can also say that it may be us who were transplanted from the aridity of Judea into the eternal grace of baptism. It goes on to say that he will not fear when the heat comes, meaning either a time of persecution or the day of judgment, and that his leaf will remain green (or that his branches will remain leafy), such that he should never fear aridity, for the grace of all the virtues will germinate. Thus, when a dry spell arrives, when the Lord of wrath commands the clouds not to send any rain on Israel, this person will not fear. And the following line, “nor will he cease to bear fruit,” can help explain the passage in the Gospel of Mark where the Lord comes to a fig tree and finds no fruit on it, since it was not yet the season, and then curses it that it would never bear fruit again. For anyone “who trusts in the Lord and whose trust is the Lord” will have no fear in a time of Judaic aridity, but he will always bear fruit who believes in him who died for us and will die no more, in him who said “I am the life.”

[AD 420] Jerome on Jeremiah 17:7-8
(Vers. 7, 8.) Blessed is the man who trusts in the Lord, and the Lord will be his hope (or confidence): and he will be like a tree, which is transplanted (or fruitful) over the waters, which sends its roots to the moisture, and will not fear when heat comes: and its leaves will be green (or its branches flourishing), and in the time of drought it will not be anxious (or will not fear) nor will it ever cease to bear fruit. Let this be said about the Jews and heretics, who have hope in man, namely in their Christ, whom they think to be not the Son of God, but a pure man who is to come. On the other hand, the man of the Church, who has confidence in the Lord, hears this: 'And know that the Lord himself is God' (Psalm 99:3). He has confidence in the Lord, and he will be compared to that tree, about which it is also sung in the first psalm: 'And he will be like a tree, planted near the streams of water, which will bear its fruit in due season, and its leaves will not wither.' But over the waters, the grace of the Holy Spirit, various gifts. He sends his roots to the moisture: so that he may receive abundance from the Lord. But we can also say in another way, that we have been translated from Jewish dryness into the eternal grace of baptism. And he will not fear, he says, when the heat comes, or the time of persecution, or the day of judgment: And its leaf will be green, or there will be leafy branches in it: so that he may never fear dryness, but may bring forth the grace of all virtues. And when the time, or year, of dryness comes, it will not be afraid, when the Lord, angry, commands the clouds not to rain upon Israel (Isaiah 5). And what follows: it will not cease to bear fruit, that place which is written in Mark, when the Lord comes to the fig tree, and does not find fruit in it, because it was not yet the time, and curses it, so that it does not bear fruit forever, can explain (Mark 11). For whoever trusts in the Lord, the Lord is his confidence, even in times of drought he will not fear; but he will always bring forth fruit, believing in him who once died for us and will never die again (Romans VI), and he says: I am the life (John XIV, 6).

[AD 430] Augustine of Hippo on Jeremiah 17:7
“They shall not be ashamed in the evil time.” In the day of trouble, in the day of distress, they shall not be “ashamed,” as one is ashamed whose hope deceives him. Who is the person who is “ashamed”? The one who says, “I have not found that which I was in hope of.” Nor undeservedly either. You hoped for it from yourself or from a person, your friend. But “cursed is one who puts his trust in humankind.” You are ashamed because your hope has deceived you; your hope that was based on a lie. - "Expositions of the Psalms 37.8"
[AD 430] Augustine of Hippo on Jeremiah 17:7-8
No, I say that either before the law, or in the time of the Old Testament, they were freed from sins, not by their own power, because “cursed is everyone who has put his hope in humankind,” and without any doubt those are under this curse whom also the sacred psalm notifies, “who trust in their own strength,” nor by the old covenant that gives birth to bondage49 … but I say that they were freed by the blood of the Redeemer, who is the one Mediator of God and people, the Christ Jesus.

[AD 542] Caesarius of Arles on Jeremiah 17:7-8
You have begun to love what is outside of yourself. You have gone outside of yourself. When a person’s love goes away from him toward things that are outside of him, he begins to become vain along with useless goods, and somehow to spend his substance like the prodigal son. He is emptied. He is poured forth. He becomes a beggar. However, we must not despair even of such people when they begin to repent. May God grant this to them: “He came to himself.” Now if he came to himself, he had gone outside of himself. Just as he remained in himself when he fell away, so he should not remain in himself when he fell away, so he should not remain in himself when he returns. Therefore, let him keep himself close to God. Let him deny himself so he will not fall again. What does to deny oneself mean? Let him not confide in his own strength, let him realize that he is human, and let him look to the prophetic word: “Cursed is the one who trusts in human beings.”

[AD 202] Irenaeus on Jeremiah 17:9
For this reason it is said, “Who shall declare his generation?” since “he is man, and who shall recognize him?” But one to whom the Father who is in heaven has revealed him knows him, so that he understands that he who “was not born either by the will of the flesh or by the will of man” is the Son of man, that is, Christ, the Son of the living God. For I have shown from the Scriptures that no one of the children of Adam is as to everything, and absolutely, called God or named Lord. But that he is himself in his own right, beyond all people who ever lived, God, and Lord, and King eternal and the incarnate Word, proclaimed by all the prophets, the apostles and by the Spirit, may be seen by all who have attained to even a small portion of the truth. Now, the Scriptures would not have testified these things of him, if, like others, he had been a mere man. But that he had, beyond all others, in himself that pre-eminent birth that is from the most high Father, and also experienced that pre-eminent generation that is from the Virgin, the divine Scriptures do in both respects testify of him.

[AD 220] Tertullian on Jeremiah 17:9
For it is of him that Isaiah writes: “A man of suffering and acquainted with the bearing of weakness.” Jeremiah writes: “He is man, and who has known him?” And Daniel writes: “On the clouds he came as the son of man.” The apostle Paul likewise says: “The man Christ Jesus is the one mediator between God and humankind.”

[AD 220] Tertullian on Jeremiah 17:9
The Father, now that he has made him a little lower than the angels, will crown him with glory and honor and will put all things beneath his feet. Then those who pierced him will know who he is and will strike their breasts, tribe to tribe—because in fact they formerly failed to recognize him in the humility of human condition. “And he is man,” says Jeremiah, “and who shall know him?” Because also, Isaiah says, “His nativity, who shall tell of it?”

[AD 325] Lucius Caecilius Firmianus Lactantius on Jeremiah 17:9
David also said in the forty-fourth psalm, “Your throne, O God, is forever and ever. The scepter of your kingdom is a scepter of uprightness. You have loved righteousness. You have hated wickedness. Therefore God, your God, has anointed you with the oil of gladness.” By this word he also shows his name, since (as I have shown above) he has called Christ from his anointing. Then, that he was also man, Jeremiah teaches, saying, “And he is a man, and who shall know him?” Also Isaiah: “And God shall send to them a man who shall save them, shall save them by judging.”

[AD 397] Ambrose of Milan on Jeremiah 17:9
The apostle says, “For God, sending his own Son in the likeness of sinful flesh, and for sin condemned sin in the flesh, that the righteousness of the law might be fulfilled in us.” He does not say “in the likeness of flesh,” for Christ took on himself the reality, not the likeness, of flesh. Nor does he say in the likeness of sin, for he did not sin but was made sin for us. Yet he came “in the likeness of sinful flesh.” That is, he took on him the likeness of sinful flesh, the likeness, because it is written, “He is man, and who shall know him?” He was man in the flesh, according to his human nature that he might be recognized, but in power he was above humanity, that he might not be recognized, so he has our flesh but has not the failings of this flesh.

[AD 403] Epiphanius of Salamis on Jeremiah 17:9
How can they declare the Savior a mere man, conceived of a man’s seed? How will he “not be known,” as Jeremiah says of him, “he is man, but who shall know him?” For the prophet, describing him, said, “Who shall know him?” But if he meant a mere man, surely his father would know him, and his mother, his relatives and neighbors, those who lived with him and his fellow townspeople. But that which came to birth is born of Mary, while the divine Word came from above. He was truly begotten not in time and without a beginning, not of a man’s seed but of the Father on high. But in the last days39 he consented to enter a virgin’s womb and fashion his flesh from her, patterned after himself. This is why Jeremiah says, “And he is man, but who shall know him?” He came from above as God, the only-begotten, divine Word.

[AD 420] Jerome on Jeremiah 17:9
Symmacus translates this passage thus: “The heart of everyone is inscrutable. Yet, who is the man who can find it?” It is customary by our own good wish, therefore, but not according to objective knowledge, to use this passage to argue against the Jews that the man in question is the Lord and Savior, according to the dispensation of the assumed flesh, and that no one shall be able to know the mystery of his nativity, according to what is written: “Who will explain his generation?” except God alone, who probes the secrets and returns to each one according to his works. But it is better that we simply accept that no one knows the secrets of another’s thoughts except God alone, for it says above, “Accursed is the person who trusts in humankind” and, “Blessed is the one who trusts in the Lord.” Hence, lest we think ourselves to be sure of human judgment, the psalmist implies that almost every heart is perverse, saying, “Cleanse me from hidden thoughts, O Lord, and spare your servant from foreigners,” without doubt meaning foreign thoughts. Also in Genesis, it is written, “God saw how great human malice was on the earth and that every thought of the human heart was intent on evil continuously”;8 and again, “The senses and the thoughts of a person’s heart are prone to evil from his adolescence.” Through these texts, we learn that God alone knows a person’s thoughts. Yet, if it is said of the Savior that “Jesus saw what they were thinking,” and if no one is able to see one’s thoughts except God alone, then Christ is God, “who examines hearts and probes the mind and gives to each one according to his works.”

[AD 420] Jerome on Jeremiah 17:9-10
(Verse 9, 10.) The heart of all is perverse and inscrutable, who can understand it? I am the Lord, searching the heart and testing the kidneys, who gives to each according to their ways and according to the fruit of their inventions. LXX: The heart is deep above all, and man is, who can know him? and so on. The Hebrew word Enos is written with four letters, Aleph and Nun and Vau and Sin. Therefore, if Enos is read, it means 'man', but if Anus, it is inscrutable or desperate, because no human heart can find it. But Symmachus interpreted this passage as follows: Inscrutable is the heart of all: but who is the man that can find it? Some of ours, indeed, with good intentions, but not according to knowledge, use this passage against the Jews, because He is called Lord and Savior, according to the dispensation of the assumed flesh, and no one can know the mystery of His birth, according to what is written: Who shall declare His generation? (Isaiah 53:8) Unless God alone who searches the depths and renders to each according to his works. However, it is better that we simply accept that no one knows the secrets of our thoughts except God alone. For as it was said above: Cursed is the man who has hope in man. And conversely: Blessed is the man who trusts in the Lord. Hence, in order for us not to think that the judgment of men is certain, it was introduced that the hearts of almost all are perverse, as the Psalmist says: Cleanse me from my hidden faults, and spare your servant from the faults of others (Psal. 19:13): undoubtedly referring to thoughts. And in Genesis: But God, seeing that the wickedness of men was great on the earth, and that every thought and intent of the heart was inclined towards evil at all times (Gen. 6:5). And again: For the sense and thought of the human heart are prone to evil from their youth (Gen. 8:21). From this we learn that only God knows our thoughts. But if it is said of the Savior: But Jesus, seeing their thoughts (Luke 9:17); and no one can see their thoughts except God alone; therefore Christ is God, who searches the hearts, and tests the kidneys; and rewards each one according to their works (Ps. 7).

[AD 430] Augustine of Hippo on Jeremiah 17:9
The inquirer, then, might say that the prophet says only that Christ is God, without any reference to his human nature. Yet, in our apostolic doctrine, Christ is not only God in whom we may safely trust but also the mediator between God and humankind—the man Jesus. The prophet explains this in the words in which he seems to check himself, and to supply the omission: “The heart,” he says “is inscrutable above all things, and he is man, and who shall know him?” He is man in order that, in the form of a servant, he might heal the hard in heart and that they might acknowledge as God him who became man for their sakes, that their trust might be not in humankind, but in God—man.

[AD 430] Augustine of Hippo on Jeremiah 17:9
His manhood was much more plainly and readily recognized by strangers, who, indeed, were not wrong in believing him to be man, but they did not understand his being God as well as man. Hence Jeremiah says, “He is man, and who shall know him?” He is a man, for it is made manifest that he is a brother. And who shall know him? For it is concealed that he is a husband [to the church]. This must suffice as a defense of our father Abraham against Faustus’s imprudence and ignorance and malice.

[AD 96] Revelation on Jeremiah 17:10
And unto the angel of the church in Thyatira write; These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet are like fine brass; I know thy works, and charity, and service, and faith, and thy patience, and thy works; and the last to be more than the first. Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. And I gave her space to repent of her fornication; and she repented not. Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds. And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works. [Jeremiah 17:10] But unto you I say, and unto the rest in Thyatira, as many as have not this doctrine, and which have not known the depths of Satan, as they speak; I will put upon you none other burden. But that which ye have already hold fast till I come. And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations: And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father. And I will give him the morning star. He that hath an ear, let him hear what the Spirit saith unto the churches.
[AD 220] Tertullian on Jeremiah 17:10
God has promised that Christ will be a light and has declared that he himself is a lantern, searching the hearts and seats of affections.

[AD 220] Tertullian on Jeremiah 17:10
The Pharisees, by justifying themselves before people, were placing in people their hope of reward. His rebuke to them had the same bearing as that of the prophet Jeremiah, “Cursed is the one who trusts in humankind.” He says next, “But God knows your hearts.” This was a reference to the power of that God who declared himself a shining light, “searching the hearts and the seats of emotions.” If he turns with hostility toward their pride, “what is exalted among people is an abomination in the sight of God,” he sets Isaiah in front of their eyes, “For the LORD of hosts has a day against all that is proud and lofty, against all that is lifted up and high.”

[AD 373] Athanasius of Alexandria on Jeremiah 17:10
For such things as these serve for exercise and trial, so that, having proved ourselves zealous and chosen servants of Christ, we may be fellow heirs with the saints. For thus Job: “The whole world is a place of trial to people on the earth.” Nevertheless, they are proved in this world by afflictions, labors and sorrows, to the end that each one may receive of God such reward as is appropriate for him, as he said by the prophet, “I am the LORD who tries the hearts and searches the reins, to give to everyone according to his ways.”

[AD 407] John Chrysostom on Jeremiah 17:10
That it belongs to God alone to know people’s secrets, hear what the prophet says: “You alone know the heart,” and again, “God examines the heart and the seat of emotions,” and Jeremiah, too, says, “The heart is inscrutable above all things, and he is man, and who shall know him?” and, “People shall look on the face but God on the heart.”

[AD 430] Augustine of Hippo on Jeremiah 17:10
God searches our heart and perceives that it is there where our treasure is, that is, in heaven.… He alone perceives what in our inward conscience each of us thinks and delights in. Delight is the end of care because our whole goal in life is to reach what we think and care about most and attain it. God, who searches the heart, therefore sees our cares.… And when he finds that our cares incline neither to the lust of the flesh, nor to the lust of the eyes, nor to the pride of life … but to the joys of things eternal, which are spoiled by no change, he provides direction for the righteous. - "Expositions of the Psalms 7.9"
[AD 420] Jerome on Jeremiah 17:11
(Verse 11.) The partridge hatches (or gathers) what it did not lay. (And as the Septuagint translated: The partridge cried out, it gathered what it did not lay.) It acquired its riches not with justice. In the middle of its days, it will leave them (or in the middle of its days, they will leave it) and in its last days, it will be foolish. Writers of natural history, both of animals and birds, as well as of trees and plants (of whom the Greek leaders are, Aristotle and Theophrastus, and among us, Pliny the Second), say that this is the nature of the partridge, to steal the eggs of another partridge, that is, to steal from another, and to incubate and care for them: and when the offspring grow up, to fly away from them, and leave behind their adoptive parent. Such are the wealthy who plunder others, and without the consideration of God's judgment, amass riches without judgment, which they leave behind in the midst of time, taken away by sudden death, when it is said to them: Fool, this night they will demand your soul from you, what you have prepared, whose will it be? And nothing is more foolish than not to foresee the last things, and to consider the fleeting as eternal. Others, however, interpret the partridge to be the most aggressive and unclean bird both because of the earlier historical account and because of another reason they state, in that it contaminates the defeated, and they interpret the devil under its name, because it has gathered riches for itself, saying to the Lord: All these things I will give to You, if You fall down and worship me (Matthew 4:9). Those riches that were gathered poorly by him will be abandoned, and they will be converted (or rather, restored) to the Lord through the Apostles; and the one who seemed to be the most prudent to himself will be considered foolish by the judgment of all. And what is said by the LXX: The partridge cried out, is to be referred to the person of the heretics, that this partridge, the devil, cried out through the leaders of the heretics, and gathered what it did not bear, and gathered a multitude of those it deceived, which it will later dismiss; and it will be proven most foolish by the judgment of all.

[AD 373] Ephrem the Syrian on Jeremiah 17:12
“The glorious throne, exalted from the beginning, is the place of our sanctuary.” Again the prophet denounces the wicked who put their hope in their riches. He exhorts them to think about the household of God, he who sits in the sacred place in the Jerusalem temple, the throne of his glory, and from there God penetrates and tests everything around him. Thus, the prophet says, “Let them know that Babylon and all the glorious kings seated on its throne were exalted and raised there by God, who dwells in our sanctuary.” Therefore, kings do not have reason to hope in their own strength, and no one should be afraid of princes, because their treasures will be taken away by the judgment of truth. For the oppression of the oppressed, oppressors will perish as the result of their own oppressive actions.

[AD 380] Apostolic Constitutions on Jeremiah 17:12
He has taken away from the ungodly the Holy Spirit and the prophetic rain and has replenished his church with spiritual grace, as the “river of Egypt in the time of firstfruits,” and has advanced the same as a house on a hill or as a high mountain, as a mountain fruitful for milk and fatness, where God is pleased to dwell. “For the Lord will dwell there to the end.” And he says in Jeremiah: “A glorious throne set on high from the beginning is the place of our sanctuary.” And he says in Isaiah: “And it shall come to pass in the last days that the mountain of the Lord shall be glorious, and the house of the Lord shall be on the top of the mountains and shall be exalted above the hills.”

[AD 420] Jerome on Jeremiah 17:12-13
(Verse 12, 13.) The throne of glory on high from the beginning, the place of our sanctification. The expectation of Israel, O Lord, all those who forsake you shall be put to shame, those who turn away shall be written (or described) on the earth; for they have forsaken the Lord, the fountain (or source) of living waters. Declare them because of their foolishness, the expectation of Israel, that is, the people of God and believers in the Lord, He is the one who made all things; whose throne is glorious and exalted from the beginning, and the place of sanctification for all believers, so that the Lord is not in a place, but that wherever He is, that place may be sanctified. On the other hand, those who forsake the Lord will be confounded with everlasting confusion, and those who depart from Him or turn away from Him will be written on the ground, deleted from the book of the living. Just as it is written of those who dwell in heaven that our citizenship is in heaven (Philippians 3), so those who forsake the Lord or turn away from Him will be written on the earth with those who have earthly desires. And the reason is clear why they are written on the earth: because they have forsaken the Lord, the fountain of life, or the Lord, the fountain of living waters, as spoken in the Gospel: If anyone is thirsty, let him come to me and drink; whoever believes in me, as Scripture says, out of his heart will flow rivers of living water. But He said this about the Spirit, whom believers in Him were going to receive (John 7:37, 38).

[AD 430] Augustine of Hippo on Jeremiah 17:12
As if anticipating that the inquirer would ask next by what plain mark a young disciple, not yet able to distinguish the truth among so many errors, might find the true church of Christ, since the clear fulfillment of so many predictions compelled him to believe in Christ, the prophet answers this question in what follows and teaches that the church of Christ, which he describes prophetically, is conspicuously visible. His words are, “A glorious high throne is our sanctuary.” This glorious throne is the church, of which the apostle says, “The temple of God is holy, which temple you are.”

[AD 253] Origen of Alexandria on Jeremiah 17:13
The “endurance of Israel” is our next subject. Just as the Savior is righteousness, truth, sanctification, so is he endurance. And there can be no way to be just without Christ, or to be holy without him or to endure without having Christ, for he is the endurance of Israel. And even if you apply these words to God, you will not in this way be impious.

[AD 420] Jerome on Jeremiah 17:13
[Daniel 7:10] "There were millions ministering unto Him, and a billion stood by His side." This was not intended to be a specific number for the servants of God, but only indicates a multitude too great for human computation. These are the thousands and tens of thousands of which we read in the Psalms: "The chariot of God is attended by ten thousands; thousands of them that rejoice. The Lord is among them" (Psalm 68:17). And in another place: "He who maketh His angels spirits, and His ministers a flaming fire" (Psalm 104:4). Now the duty of angels is twofold: the duty of one group is to bestow rewards upon just men; the duty of the other is to have charge over individual calamities.

"...The court was in session, and the books were opened." The consciences of men, and the deeds of individuals which partake of either character, whether good or bad, are disclosed to all. One of the books is the good book of which we often read, namely the book of the living. The other is the evil book which is held in the hand of the accuser, who is the fiend and avenger of whom we read in Revelation: "The accuser of our brethren" (Revelation 12:10). This is the earthly book of which the prophet says: "Let them be written on earth" (Jeremiah 17:13).

[AD 435] John Cassian on Jeremiah 17:13
We must therefore not doubt that at the time when he was chosen by Christ and obtained a place in the apostolate, the name of Judas was written in the book of the living, and then he heard as well as the rest the words, “Rejoice not because the devils are subject to you, but rejoice because your names are written in heaven.” But because he was corrupted by the plague of covetousness and had his name struck out from that heavenly list, it is appropriately said of him and of people like him by the prophet: “O Lord, let all those who forsake you be confounded. Let them who depart from you be written in the earth, because they have forsaken the Lord, the vein of living waters.” And elsewhere, “They shall not be in the counsel of my people, nor shall they be written in the writing of the house of Israel, neither shall they enter into the land of Israel.”

[AD 435] John Cassian on Jeremiah 17:13
And again when all their efforts are exhausted and they have failed to deceive us, they must “be confounded and be ashamed” at the failure of their efforts, “who seek our souls to destroy them. Let them be covered with shame and confusion who desire evil against us.” Jeremiah also says, “Let them be confounded, and let not me be confounded; let them be afraid, and let not me be afraid; bring on them the fury of your wrath, and with a double destruction destroy them.”

[AD 420] Jerome on Jeremiah 17:14
He says to him who alone is the true physician, “Heal me, O Lord, and I shall be healed. Save me, and I shall be saved. You are my praise and my hope.”

[AD 420] Jerome on Jeremiah 17:14
(Verse 14) Heal me, O Lord, and I shall be healed; save me, and I shall be saved, for you are my praise. In the Gospel (Matthew 9), many physicians had cured the woman with the issue of blood, who had lost all her substance on them, yet she could not be healed by anyone except by Him who is the true physician, and whose healing is in His wings. Therefore, even now, the Prophet, having suffered reproaches from the people and being constantly surrounded by snares, desires to be healed and saved by Him whose true praise and true medicine He is.

[AD 430] Augustine of Hippo on Jeremiah 17:14
No evil person does good. And if no evil person does good, how could an evil person make himself good? He who is eternally good can make an evil person good. “Heal me, O Lord, and I shall be healed: save me, and I shall be saved.”

[AD 430] Augustine of Hippo on Jeremiah 17:14
So, the reason that we, being bad, have a good Father is in order that we may not always remain bad. No bad person can make a good one. If no bad person can make a good one, how can a bad person make himself good? The only one who can make a good person out of a bad one is the one who is always good. “Heal me, Lord,” he says, “and I shall be healed; save me, and I shall be saved.”

[AD 420] Jerome on Jeremiah 17:15-17
(Verse 15 onwards) Look, they say to me: Where is the word of the Lord? Let it come. But I am not troubled, following you as a shepherd (or not laboring, following you), and I have not desired the day of man: you know. What has come out of my lips has been right in your sight (or before your face). Do not be a source of fear to me, you are my hope in the day of affliction (or do not become a stranger to me, sparing me on the worst day). Those who do not believe in the future, speak to the Prophet: Where is the word of the Lord? Let us come: considering the dissimulation of judgment, thinking of delay. But to those, he says, speaking these things, I am not troubled, nor have I labored following you as a shepherd, either entering your footsteps. Nor was I satisfied with this end, but I did not desire the day of man, either a longer life, or the prosperous things of this age. And he calls himself a witness, whom he also calls a judge: You know. He continues: What has come forth from my lips, was right in your sight; that he has never lied, and never spoke against the will of the Lord. Be not to me, he says, a source of fear, my hope in the day of affliction. Which is clear according to the Hebrew. But according to what the Seventy translated, saying: Do not become a stranger to me, sparing me in the day of evil, the meaning is: Do not spare me in the present age, which is evil; but repay me according to my sins, so that I may have eternal rest. For I know it is written: Whom the Lord loves, he chastises; and he scourges every son whom he receives (Hebrews XII, 6). But this day is evil, either the entire age, or the day of judgment, for those who suffer because of their sins.

[AD 132] Epistle of Barnabas on Jeremiah 17:16
It is also written concerning the sabbath in the Decalogue that the Lord spoke, face to face, to Moses on Mount Sinai, “And sanctify the sabbath of the Lord with clean hands and a pure heart.” And he says in another place, “If my children keep the sabbath, then will I cause my mercy to rest on them.”

[AD 253] Origen of Alexandria on Jeremiah 17:16
“Behold, they say to me, ‘Where is the word of the Lord? Let it come.’ But I have not been weary of following you.” Jesus says to you, “Take up your cross, and follow me,” and, “Leave everything, and follow me,” and, “He who does not leave behind father and mother and follow me is not worthy to be my disciple.” If, then, you become such a person so as to follow Jesus in every way, and you will follow, and to the extent you do follow, you will not be weary. “For there is no hardship in Jacob, nor will distress be seen in Israel.” There is no toil in following Jesus. The following itself takes away the toil. In order that we may no longer be weary, since we are weary before beginning to follow him, that is why he says, “Come to me, all who are weary and are heavy laden, and I will give you rest.”

[AD 397] Ambrose of Milan on Jeremiah 17:16
I dearly love those priests and deacons who, once they have finished a duty, do not allow themselves to remain away any longer. As the prophet says, “I am not weary following after you.” Who can be weary following Jesus, for he says, “Come to me, all you who labor and are burdened, and I will give you rest.” Let us, then, always follow Jesus and never falter, for if we follow him, we never fail, because he gives his strength to his followers. The nearer you are to this strength, the stronger you will be. Sometimes, while we follow him, our adversaries say to us, “Where is the word of the Lord? Let it come.” Let us not grow weary of following him, and let us not be turned aside when confronted by a crafty question. It was said to the prophet when he was being sent to prison and cast into a pit of mire, “Where is the word of the Lord? Let it come.” But he followed it the more and therefore reached the goal and received the crown, because he was not weary following Jesus. “There is no weariness in Jacob, nor will sorrow be seen in Israel.”

[AD 420] Jerome on Jeremiah 17:16
Let us give thanks to God, and let us ask him in his good will to be our shield and crown, that we may never depart from him and that we may follow him and declare with Jeremiah, “I was not weary of following you.” To him be glory forever and ever. Amen.

[AD 430] Augustine of Hippo on Jeremiah 17:16
The Lord has indeed made every day—not only has made but also continues to make. I mean, he makes every day as follows: he makes his sun rise on the good and the bad and sends rain on the just and the unjust. So we are not to imagine that this ordinary kind of day, which is common to good and bad alike, is meant in this place, where we heard, “This is the day that the Lord has made.” What particular sort of day can it be when it says, “Let us exult and be joyful in it”? What sort, but a good one? What sort, but a very choice, lovable, desirable one, the sort about which Jeremiah said, “And I have not yearned for the day of men, you know it well”?

[AD 435] John Cassian on Jeremiah 17:16
For it is but little for a monk to have once made his renunciation, that is, in the early days of his conversion to have disregarded the present world, unless he continues to renounce it daily. For to the very end of this life we must with the prophet say this: “And I have not desired the day of man, you know it well.” Wherefore also the Lord says in the Gospel: “If anyone will come after me, let him deny himself and take up his cross daily and follow me.”

[AD 420] Jerome on Jeremiah 17:18
(Verse 18.) Let those who pursue me be put to shame, while I am not put to shame. Let them fear, while I do not fear. Bring upon them the day of affliction, and crush them with double contrition. The Prophet curses against them, who reproach him with the word of the Lord, and say: Where is the word of the Lord? Let it come, that those who pursue him may be put to shame and may be ashamed and may return to salvation, so that they may fear the liars and not the one who predicts the truth. And when the day of vengeance comes, it will crush them with a twofold affliction, hunger and sword.

[AD 420] Jerome on Jeremiah 17:19-20
(Verse 19, 20.) This is what the Lord says to me: Go and stand at the gate (or gates) of the people's children: through which the kings of Judah enter and exit, in all the gates of Jerusalem. And you shall say to them; Listen to the word of the Lord, kings of Judah, and all Judah and all the inhabitants of Jerusalem, who enter through these gates. Because, he says, they despise hearing your words, and they do not come to you to seek the wisdom of God, you go to the most famous place, either the gate of the temple or the gate of the city, through which the kings and the entire crowd enter and exit, so that they may be compelled by necessity to hear, and you shall proclaim the word of the Lord continuously, whether convenient or inconvenient (1 Timothy 4): and no excuse shall remain among them, that they did not do it because they did not hear.

[AD 420] Jerome on Jeremiah 17:20-27
(Verse 20 and following) Thus says the Lord: Guard your souls, and do not carry burdens on the Sabbath day, or bring them through the gates of Jerusalem. And do not cast burdens out of your houses on the Sabbath day, and you shall not do any work, and sanctify the Sabbath day, as I commanded your fathers. But they did not listen, nor inclined their ear, and they stiffened their necks (and what is not found in Hebrew, against their fathers), so that they would not listen to me, and would not receive discipline. And it will be, says the Lord, if you listen to me, that you shall not carry burdens through the gates of this city on the Sabbath day, and if you sanctify the Sabbath day and do not do any work on it, then the kings and princes occupying the throne of David shall enter through the gates of this city. They shall arrive in chariots and on horses, along with their princes, the men of Judah, the inhabitants of Jerusalem. And this city shall be inhabited forever. And they shall come from the cities of Judah, and from the surrounding of Jerusalem, and from the land of Benjamin, and from the plains, and from the mountains, and from the south, bearing burnt offerings and sacrifices (or incense) and grain offerings (or manna) and frankincense, and they shall bring an offering (or praise) into the house of the Lord. But if you will not listen to me to hallow the Sabbath day, and not to carry burdens, and not to bring them in through the gates of Jerusalem on the Sabbath day, then I will kindle a fire in its gates, and it shall devour the palaces of Jerusalem, and it shall not be quenched. I decided to disregard the commandment of the Sabbath restored through Jeremiah in vain, so that we may understand all at the same time. He who does not carry the burdens of sins on the day of rest and Sabbath guards his soul: nor does he bring them through the gates of Jerusalem, which virtues we should receive. And do not, he says, cast off burdens from your houses. For they are not to be carried, but to be completely cast away. And do not do any work, either servile or that which is written: 'Food for the stomach and the stomach for food,' but God will destroy both this and that (I Cor. VI, 13); but that work must be done, of which the Savior speaks; 'Work for the work that does not perish' (John VI, 27). Sanctify, he says, the Sabbath day, so that we may spend all the time of our life in sanctification, just as our fathers Abraham, Isaac, and Jacob did. And when God commanded these things, they did not incline their ear, certainly not their mind, nor their flesh; but they hardened their neck, rejecting the yoke of the Law, and having a likeness to untamed animals by metaphor. Let us see what is the reward of those who do not bear the burdens of the Sabbath day and sanctify it. Kings will enter through the gates of this city, whose heart is in the hand of God, and who reign over their bodies (Prov. 21); and princes sitting on the throne of David, in order to imitate the example of Christ, and those who ride in chariots and on horses, of whom it is written: The chariots of God are ten thousand, even thousands of angels; the Lord is among them as in Sinai, in the holy place (Psalm 68:17). And elsewhere: Your horses are a salvation (Habakkuk 3:8). Every man who confesses God and dwells in Jerusalem, of which it is said: His place is in Salem (or Jerusalem), that is, in peace, and his dwelling is in Zion (Psalm 75:2), and the Church of God will dwell there forever. They will come from the cities of Judah and from around Jerusalem, of which we have already spoken, and from the land of Benjamin, who is the son of strength and the right hand, and from the plains, which in Hebrew is called Sephela, and it signifies a plain understanding of history, and from the mountains, namely the lofty doctrines, and from the South, of which it is written: God will come from the South (Habbakuk 3:3). Where there is heat and full light, and where all cold is expelled: Carrying, he says, holocausts, consecrating themselves to God, and a victim, or incense, so that they may say: 'A sacrifice of a broken spirit, O Lord' (Psalm 50:19). And, we are a sweet odor of Christ in every place (1 Corinthians 2:15). And elsewhere: 'Let my prayer be directed as incense in your sight' (Psalm 140:2). And the sacrifice, for which the 70 translators themselves put down the Hebrew word Manaa, which, by a most wicked custom, indeed the negligence of the scribes, is read as manna in our language. And thus, concerning which it is written: 'Why do you bring me frankincense from Sheba?' (Jeremiah 6:20) And they bring an offering, which in Hebrew is called Thoda, and can be translated into a thanksgiving. And which praise the Septuagint translated. Into the house of David, no doubt into the Church. These are the rewards of those who sanctify the Sabbath and are not burdened with any weight. But if, he says, you do not listen to my commandments, and do what I have not commanded to be done: I will kindle a fire in its gates, that is, in Jerusalem, about which it is said: 'All of them, like a baker's oven, their hearts' (Hosea 7:4): who devour houses or streets of Jerusalem, which the LXX translated as alleys, Aquila and Symmachus as turrets, and are called Armanoth in Hebrew. And this fire will never be extinguished, as the Apostle says: Each one's work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each person's work (1 Cor. 3:13). And again: If anyone's work is burned up, they will suffer loss but yet will be saved - even though only as one escaping through the flames (ibid., 15). But if our Judaizing opponents reject this figurative interpretation, they will either be compelled to be Jews and observe the Sabbath and circumcise foreskins, or certainly censure the Savior who commanded the paralyzed man on the Sabbath to take up his bed, as the Evangelist says: Therefore the Jews sought all the more to kill Him, because He not only broke the Sabbath, but also said that God was His Father, making Himself equal with God (John 5:18).
