Jeremiah 38:6 Douay-Rheims

Then they took Jeremias and cast him into the dungeon of Melchias the son of Amelech, which was in the entry of the prison: and they let down Jeremias by ropes into the dungeon, wherein there was no water, but mire. And Jeremias sunk into the mire.

“How distressed I am, mind you, when I call to mind that on the festival days the multitudes assembled resemble the broad expanse of the sea, but now not even the smallest part of that multitude is gathered together here. Where are they now who oppress us with their presence on the feast days?… Now if they make the summer season their excuse, for I hear of their saying things of this kind, "the present stifling heat is excessive, the scorching sun is intolerable, we cannot bear being trampled and crushed in the crowd and to be steaming all over with perspiration and oppressed by the heat and confined space." … What then am I to say to those who advance these pretexts? I would remind them of the three children in the furnace and the flame, who when they saw the fire encircling them on all sides, enveloping their mouth and their eyes and even their breath, did not cease singing that sacred and mystical hymn to God, in company with the universe but standing in the midst of the pyre, sent up their song of praise to the common Lord of all with greater cheerfulness than they who abide in some flowery field. Together with these three children I should think it proper to remind them also of the lions that were in Babylon, and of Daniel and the den: 2 and not of this one only but also of another den, and the prophet Jeremiah and the mire in which he was smothered up to the neck.”

“In this part is shown the persecution of the prophet on account of his true preaching: and it is divided into three parts. First he sets down the preaching, he was speaking: for although he was in prison, yet many came to him; in which he threatens death to those who remain: whoever shall remain in this city shall die. And he promised safety to those who fled: but whoever shall flee (...) shall live. The capture of the city: by being delivered, it shall be delivered. And these three things he set down above in 21: whence it seems to be continued, according to the order of the history, to that. Secondly he sets down the persecution: where he sets down the impious petition of the princes: for they seek death: and the princes said. Wis. 2: let us circumvent the just man, because he is contrary to our works. They accuse his preaching: for of set purpose he weakens the hands of the men: which is against the prophetic office. Isa. 35: strengthen the weakened hands, and make firm the feeble knees. And they pervert his intention: since this man does not seek peace. Gal. 4: am I then become an enemy, speaking the truth to you? But Jeremiah did not wish to take away the heart of resisting; but he said those things for the good and salvation of the people, at the command of the Lord. He also sets down the foolish assent of the king: and king Zedekiah said. Whence he is not excused, although he sinned less. John 19: therefore he who delivered me to you has the greater sin. He also sets down their diligent execution: they took Jeremiah, therefore, and cast him into the pit, a cistern without water. Ps. 87: they have put me in the lower pit, in the dark places, and in the shadow of death. And he designates the letting down of the prophet: and so Jeremiah went down into the mire. Ps. 68: I am fixed in the mire of the deep, and there is no substance. Thirdly, the liberation is set down. Here he sets down two things. First, that he is freed from prison; secondly, that he is freed from fear of death, there, and king Zedekiah sent, and took Jeremiah to himself. Concerning the first, four things. First he describes the one petitioning, Abdemelech, that is, signifying "servant of the king"; which he says on account of humility. Rom. 1: Paul, a servant of Christ Jesus, etc. An Ethiopian, on account of the mortification of the flesh. Ps. 67: Ethiopia shall hasten her hands unto God. Cant. 1: I am black, but beautiful. A man, on account of strength of soul; a eunuch, on account of chastity. Matt. 19: there are eunuchs who have castrated themselves for the kingdom of heaven. Who was in the house of the king, Phil. 3: our conversation is in the heavens. Wis. 3: the eunuch who has not wrought iniquity with his hands, nor thought most wicked things against God: for to him shall be given the choice gift of faith, and a most acceptable lot in the temple of God. Secondly he sets down the petition, designating the place of the petition: now the king was sitting in the gate of Benjamin, which namely led into the tribe of Benjamin. And he sets down the petition, and Abdemelech went out from the house of the king, and spoke to the king (...) for there is no more bread in the city; as if to say: from the time he was shut in, the bread failed. Or, it was not necessary for him to be shut in, since we are all besieged, and in want. Wis. 11: by what things a man sins, by the same also he is tormented. Thirdly, the obtaining is set down: and so the king commanded. Fourthly, the execution is set down: Abdemelech, therefore, taking men with him, entered the house of the king (...) and took from there old rags and worn-out things that had rotted, on account of the tribulations which they endured. Heb., last chapter: remember the leaders who have spoken to you the word of God; considering the end of their conversation, imitate their faith. Or because, literally, they are softer. By the cords, the precepts of God. Eccl. 4: a threefold cord is broken with difficulty. In the vestibule of the prison, that is, in the court. For the vestibule is called the house before the king's chamber, where garments are kept: whence every court is called a vestibule.”

“Then took they Jeremiah,.... Having the king's leave, or at least no prohibition from him; they went with proper attendants to the court of the prison, and took the prophet from thence: and cast him into the dungeon of Malchiah the son of Hammelech, that was in the court of the prison; this was a dungeon that belonged to the prison which Malchiah had the care of, or which belonged to his house, which was contiguous to the court of the prison. The Targum renders it, Malchiah the son of the king; and so the Septuagint and Arabic versions; but it is not likely that Zedekiah should have a son that was set over his dungeon, or to whom one belonged, or should be called by his name: here the princes cast the prophet, in order that he should perish, either with famine or suffocation, or the noisomeness of the place; not caring with their own hands to take away the life of a prophet, and for fear of the people; and this being a more slow and private way of dispatching him, they chose it; for they designed no doubt nothing less than death: and they let down Jeremiah with cords; there being no steps or stairs to go down into it; so that nobody could come to him when in it, or relieve him: and in the dungeon there was no water, but mire; so Jeremiah sunk in the mire; up to the neck, as Josephus (q) says. Some think that it was at this time, and in this place, that Jeremiah put up the petitions to the Lord, and which he heard, recorded in Lam 3:55; and that that whole chapter was composed by him in this time of his distress. (q) Antiqu. l. 10. c. 7. sect. 5.”

“dungeon--literally, the "cistern." It was not a subterranean prison as that in Jonathan's house (Jer 37:15), but a pit or cistern, which had been full of water, but was emptied of it during the siege, so that only "mire" remained. Such empty cisterns were often used as prisons (Zac 9:11); the depth forbade hope of escape. Hammelech-- (Jer 36:26). His son followed in the father's steps, a ready tool for evil. sunk in the mire--Jeremiah herein was a type of Messiah (Psa 69:2, Psa 69:14). "I sink in deep mire," &c.”
