:
1 The word which came unto Jeremiah from the LORD, when king Zedekiah sent unto him Pashur the son of Melchiah, and Zephaniah the son of Maaseiah the priest, saying, 2 Inquire, I pray thee, of the LORD for us; for Nebuchadrezzar king of Babylon maketh war against us; if so be that the LORD will deal with us according to all his wondrous works, that he may go up from us. 3 Then said Jeremiah unto them, Thus shall ye say to Zedekiah: 4 Thus saith the LORD God of Israel; Behold, I will turn back the weapons of war that are in your hands, wherewith ye fight against the king of Babylon, and against the Chaldeans, which besiege you without the walls, and I will assemble them into the midst of this city. 5 And I myself will fight against you with an outstretched hand and with a strong arm, even in anger, and in fury, and in great wrath. 6 And I will smite the inhabitants of this city, both man and beast: they shall die of a great pestilence. 7 And afterward, saith the LORD, I will deliver Zedekiah king of Judah, and his servants, and the people, and such as are left in this city from the pestilence, from the sword, and from the famine, into the hand of Nebuchadrezzar king of Babylon, and into the hand of their enemies, and into the hand of those that seek their life: and he shall smite them with the edge of the sword; he shall not spare them, neither have pity, nor have mercy. 8 And unto this people thou shalt say, Thus saith the LORD; Behold, I set before you the way of life, and the way of death. 9 He that abideth in this city shall die by the sword, and by the famine, and by the pestilence: but he that goeth out, and falleth to the Chaldeans that besiege you, he shall live, and his life shall be unto him for a prey. 10 For I have set my face against this city for evil, and not for good, saith the LORD: it shall be given into the hand of the king of Babylon, and he shall burn it with fire. 11 And touching the house of the king of Judah, say, Hear ye the word of the LORD; 12 O house of David, thus saith the LORD; Execute judgment in the morning, and deliver him that is spoiled out of the hand of the oppressor, lest my fury go out like fire, and burn that none can quench it, because of the evil of your doings. 13 Behold, I am against thee, O inhabitant of the valley, and rock of the plain, saith the LORD; which say, Who shall come down against us? or who shall enter into our habitations? 14 But I will punish you according to the fruit of your doings, saith the LORD: and I will kindle a fire in the forest thereof, and it shall devour all things round about it.
[AD 420] Jerome on Jeremiah 21:1-2
(Chapter 21, verses 1 and following) The word that came to Jeremiah from the Lord when King Zedekiah sent to him Pashhur the son of Malchiah and Zephaniah the son of Maaseiah, the priest, saying, 'Inquire of the Lord for us, for Nebuchadnezzar king of Babylon is making war against us. Perhaps the Lord will deal with us according to all his wonderful deeds and will make him withdraw from us.' Pashhur the priest, the son of Immer, who struck Jeremiah, had a son named Pashhur. But Phasur is the son of Melchiah. This is why, so that no one might think he is the same. And King Zedekiah sends to the Prophet, not wanting either the people or the leaders to know, in order to secretly through messengers inquire, what judgment the Lord has against the city of Jerusalem and the people of Judah. And what he brings forward: Because King Nebuchadnezzar of Babylon is making war against us, it is already shown that Jerusalem is besieged, Sedekiah inquires about this from the Prophet. And it should be noted, that in the Prophets, especially in Ezekiel and Jeremiah, the order of kings and times is not followed, but rather in reverse, that which happened later is recounted first, and that which happened earlier is recounted later. For it is one thing to write history, and another to write prophecy: as in this place, Zedekiah, who was captured with the city of Jerusalem, is mentioned sending a letter to Jeremiah, and at the same time when Jerusalem was under siege, and later the history of his brother Jehoiakim is narrated, who was king before him, and Jehoiachin. That is, Jechoniah, who was the son of Joachim, about whom it will be said in the following.

[AD 420] Jerome on Jeremiah 21:3-6
(Vers. 3 seqq.) And Jeremiah said to them: Thus shall you say to Zedekiah: Thus saith the Lord God of Israel: Behold, I will turn back the weapons of war (or the weapons of warfare) which are in your hands, wherewith you fight against the king of Babylon, and the Chaldeans that besiege you round about the walls: and I will gather them (or it) together in the midst of this city, and I will fight against you with stretched-out hand, and with a strong arm (or an exalted one), and in fury, and in wrath, and in great indignation. And I will strike the inhabitants of this city: both men and animals will die from a great pestilence. In vain, he says, do you want to resist the Chaldeans who are besieging you, and prepare your weapons of war, of which you will only have use in the middle of the city, so that you seem to be armed. However, against those besieging you, I will conquer you with an outstretched hand and a strong arm, and I will strike you with my fury and indignation: so that both you and everything that breathes may die in the middle of the city from hunger and pestilence. Indeed, we have read that this indeed happened. Without any crown and without any noise of the combatants, such a great city was captured by siege, that they did not have those whom they had conquered, but only those whom they had captured. Better, he says, were those wounded by the sword than those killed by hunger.

[AD 420] Jerome on Jeremiah 21:7
(Verse 7) And after these things, the Lord said: I will give Sedecias, king of Judah, and his servants, and his people, and those who have been left in this city from the plague, and the sword, and famine, into the hand of Nebuchadnezzar, king of Babylon, and into the hand of their enemies, and into the hand of those who seek their lives. And he will strike them with the edge of the sword, and he will not show mercy, and he will not spare, and he will not have pity. What we have translated is not found in the Septuagint. And concerning what we have said: He will not be moved, neither will he spare, nor will he have mercy, the Seventy translated: I will not spare, neither will I have mercy. And it is better according to the Hebrew, that the sentence may seem cruel and unyielding, more like that of the Babylonian king than of the Lord. But first it was prophesied concerning the entire city: now it is specifically predicted of Zedekiah and his people, who will remain after the plague, that he is to be captured by the king of Babylon, Nebuchadnezzar, and to be killed with his friends by the sword. Nor should he hope for any mercy from him, whom he betrayed his covenant and friendship by perjury.

[AD 99] Clement of Rome on Jeremiah 21:8
Through your works you have revealed the everlasting structure of the world. You, Lord, created the earth. You are faithful throughout all generations, righteous in your judgments, marvelous in strength and majesty, wise in creating and prudent in establishing what exists. You are good in all that is observed and faithful to those who trust in you. You are merciful and compassionate. You forgive us our sins and our injustices, our transgressions and our shortcomings. Do not take into account every sin of your servants and slave girls, but cleanse us with the cleansing of your truth and “direct our steps to walk in holiness and righteousness and purity of heart,” and “to do what is good and pleasing in your sight” and in the sight of our rulers. Yes, Lord, “let your face shine on us” in peace “for our good,” that we may be sheltered “by your mighty hand” and delivered from every sin “by your uplifted arm”;23 deliver us as well from those who hate us unjustly. Give harmony and peace to us and to all who dwell on the earth, just as you did to our ancestors when they reverently “called on you in faith and truth,” that we may be saved, while we render obedience to your almighty and most excellent name, and to our rulers and governors on earth.

[AD 100] Didache on Jeremiah 21:8
There are two ways, one of life and one of death; but there exists a great difference between the two ways. The way of life, then, is this: First, you shall love God, who made you; second, love your neighbor as yourself. Anything that you would not want to happen to you, you also should not do to another. And of these sayings, the teaching is this: Bless those who curse you, and pray for your enemies, and fast for those who persecute you. For what good is it if you love those who love you? Do not also the Gentiles do the same? Rather, love those who hate you, and you shall not have an enemy. Abstain from fleshly and worldly lusts. If someone strikes you on your right cheek, turn to him the other also, and you shall be perfect. If someone insists on you going one mile, go with him two. If someone takes away your cloak, give him your coat as well. If someone takes something from you, do not ask for it back, for indeed you are not able to do so. Give to everyone who asks you, and do not ask for it back, because the Father wills that the blessings we have received should be given to everyone. Happy is the one who gives according to the commandment; for that person is guiltless. Woe to the one who receives. For if one having need receives, he is guiltless; but one who receives even when he does not need it will pay the penalty because he received and because of what he received. He will be taken into confinement and examined concerning the things that he has done, and he shall not escape from there until he pays back the last farthing. It has also been said concerning this, Let your alms sweat in your hands until you know to whom you should give.…
And the way of death is this: First of all it is evil and full of cursings, murders, adulteries, lusts, fornications, thefts, idolatries, magic arts, witchcrafts, rapines, false witnessings, hypocrisies, double-mindedness, deceit, pride, depravity, self-will, greediness, filthy talking, jealousy, overconfidence, loftiness, boastfulness; persecutors of the good, hating truth, loving a lie, not experiencing any reward for righteousness, not cleaving to good or to righteous judgment, not looking out for what is good but for what is evil; from whom meekness and endurance are far, loving vanities, pursuing vengeance, not pitying a poor person, not working for the afflicted or knowing God who made them, murderers of children, destroyers of the handiwork of God, turning away from the person that is in want, afflicting the one who is distressed, advocates of the rich, lawless judges of the poor, utter sinners. Be delivered, children, from all these.
See that no one causes you to err from this way of teaching, since apart from God it teaches you. For if you are able to bear the whole yoke of the Lord, you will be perfect. But if you are not able, do what you can. And concerning food, bear what you are able, but be vigilant in rejecting what is sacrificed to idols, for it has been used in the service of dead gods.

[AD 311] Methodius of Olympus on Jeremiah 21:8
It was not God’s law that became the cause of my being brought into subjection to corruption, but the devil, that he might be made manifest. He wrought evil through that which is good. The inventor of evil became and was proved to be the greatest of all sinners. “For we know that the law is spiritual.” So the law cannot injure anyone in any way. Spiritual things are far removed from irrational lust and sin. “But I am carnal, sold under sin.” This means, “I am carnal and placed between good and evil as a voluntary agent, so that I have it in my power to choose what I wish.” For “behold, I set before you life and death.” This means, “Death would result from disobedience of the spiritual law, that is, of the commandment, and from obedience to the carnal law, that is, the counsel of the serpent.” By such a choice I am sold to the devil, fallen under sin. Hence evil, as though besieging me, clings to me and dwells in me. Justice gives me up to be sold to the evil one, as a result of having violated the law.

[AD 420] Jerome on Jeremiah 21:8-10
(Verse 8 and following) And to this people you shall say: Thus says the Lord: Behold, I set before you the way of life and the way of death. Whoever remains in this city shall die by the sword, by famine, and by pestilence. But whoever goes out and surrenders to the Chaldeans who are besieging you shall live, and shall have his life as a prize of war. For I have set my face against this city for harm and not for good, declares the Lord. It shall be given into the hand of the king of Babylon and he shall burn it with fire. Those who were sent by the king and came to the Prophet to plead with him to inquire of the Lord for them, received an answer concerning the king of Judah and what they should report to him. Now he encourages them to respond to the people and advises them to surrender to the Chaldeans against the king's will, which the Prophet knows was dangerous. Therefore, he curses the day of his birth, saying: 'Cursed be the day on which I was born.' (Jeremiah 20:14). And why did I come out from the womb, to see toil and sorrow (Ibid., 18)? Not because it is a trivial matter, nor yet to give advice to those already captured, that they should willingly submit to captivity, as if a shipwreck were ordered on those about to suffer it, so that, before the shipwreck and the ship being dashed to pieces, they should seize the oars and planks and cast themselves into the waves; but because it is more tolerable to live in whatever way, having been captured, than to be consumed by the sword, famine, and pestilence. There are those who have expounded this passage as follows, according to a metaphorical interpretation: the secular disciplines, and especially philosophy, are better than remaining within that Church in which there is hunger for the word of God, and the entire people die from both a scarcity of doctrine and a heretical plague.

[AD 420] Jerome on Jeremiah 21:11-12
(Verse 11, 12.) And to the house of the king of Judah, hear the word of the Lord, O house of David. Thus says the Lord, Judge in the morning, and deliver the oppressed from the hand of the oppressor, lest my indignation goes forth like fire and is kindled with none to quench it, because of the evil of your deeds. The phrase 'because of the evil of your deeds' is not found in the Septuagint. Because above (Al. already above) it had said, And to this people you shall say, Thus says the Lord, subsequently it now adds, and to the house of the king of Judah: so that it is understood, you shall say, thus says the Lord: for both the higher and the lower are connected; so that the meaning is: And to this people you shall say, Thus says the Lord. But a proper speech is made to the royal house, because of whose fault the city is besieged, so that it may correct the error through repentance, and obtain the mercy of the Lord. Judge, he says, justice in the morning, not in the darkness of iniquity, but in the light of justice. And deliver the one oppressed by force, from the hand of the slanderer, so that you do not show favoritism in judgment, but that the authority of God may prevail more among you than the power of the persecutor. And if, he says, you do this, the fire of my anger will not be kindled in you, nor will it find material to consume. In this place the incredible mercy of God is demonstrated, as concerning those of whom it was said before: For I have set my face against this city for evil, and not for good; it shall be given into the hand of the king of Babylon, and he shall burn it with fire, with the judgment of the Lord already approaching, so as to provoke them to seek salvation. Not that he is unaware that the city of Jerusalem is to be taken, but because the free will of man is preserved, so that they may seem to perish not by ignorance of the future, but by their own choice. How did the Savior know that the Apostle would deny him and that he himself would be crucified? Surely he had often foretold this to the Apostles and nevertheless reminded them, desiring to correct them for repentance, so that whatever they would subsequently endure, it would happen to them by their own fault, not because of the severity of the one threatening.

[AD 420] Jerome on Jeremiah 21:13-14
(Verse 13, 14.) Behold, I am against you, O inhabitants of the solid and level valley, says the Lord, those who say, who will strike (or terrify) us? And who will enter our houses? And I will visit upon you; and what follows, according to the fruit of your endeavors, says the Lord, is not found in the Septuagint. And I will set fire to its forest, and it will consume all around it. For the inhabitants of the solid and level valley, the Septuagint translated, Behold, I am against you, who dwell in the valley of Sor () the level, for which Symmachus interpreted as a rock besieged, Theodotius as a fortified place; in the first edition of Aquila it is solid, in the second Tyre. For Tyre speaks its language, and the land of the Hebrews, and the area around it, and it sounds like a restricted place. However, it speaks against Jerusalem, which is surrounded by siege, or in the likeness of Tyre, like a vast sea, it is encircled by the Babylonian army and cannot escape. Or certainly, it sees itself as an impregnable and robust rock due to the strength of its walls and their size, and it says: Who can frighten us? And who will enter our house? When God speaks in the opposite way: I will visit you; you will not be able to escape my eye. But I will visit you for destruction, and I will repay you the fruit of your wickedness. And I will kindle a fire in your forest. Not the Babylonians, as you think, not the king of the Chaldeans; but my anger will accomplish all these things. But he calls the forest Jerusalem, and all the surrounding region, which does not have the fruitful trees of good works, because it is prepared for burning. He calls the valley beautiful because it is easily passable by enemies, and not a high mountain that can be difficult to climb, next to which it is also said in Isaiah: The vision of the Valley of Zion (Isa. 22:1). Let us refer whatever is prophesied about the royal house and the metropolis city to the ecclesiastical order and the leaders of the Churches, only those who have surrendered to pride, riches, and indulgence. Not immediately because it is the royal house, it will be saved from destruction, just as those who are of the Davidic lineage, very few have been found who pleased the Lord like David himself, Hezekiah and Josiah, and a great part of the leaders and the royal lineage as a whole provoked the wrath of the Lord against the people.
