He now employs other comparisons. Some improperly confine this to Jeremiah himself, as though he explained here before God the wrongs done to himself: but there is no doubt but that he undertakes the cause of the whole people; and his object was to encourage by his own example the faithful to lament their state so that they might obtain pardon from God. He then compares himself to a man half-dead, cast into a pit, and there left for lost. Then some improperly interpret the words, "they cast stones;" for stoning was not in the mind of the Prophet; but having said that he was fast bound in a pit or dungeon, he adds that a stone was laid over him, that lie might not come forth, as we know was the case with Daniel. (Daniel 6:16, 17.) Daniel was cast into the den of lions, and then a stone was put on the mouth of the den. So also the Prophet says, that he was bound fast in the pit, and not only that, but that a stone was laid over him, that there might be no hope of coming out; and thus the pit was like a grave. Here, then, he means that lie was reduced to the last extremity, because he had not only been taken by his enemies, but had also been cast into a pit. And, as it is well known, it is a metaphorical expression or a similitude. He adds, --

They have cut off my life in the dungeon - Or, "They destroyed my life in the pit," i. e. tried to destroy it by casting me into the cistern, and covering the month with a stone. See the margin reference.

They have cut off my life (y) in the dungeon, and cast a stone upon me.
(y) Read (Jeremiah 37:16) how he was in the miry dungeon.

They have cut off my life in the dungeon,.... Jarchi interprets it,
"they bound me in the prison.''
Jeremiah was both in a prison and in a dungeon, where he was deprived of the society of men, as if he had been dead; and he was in danger of losing his life; but whether any respect is had to it here is not certain: it seems rather to respect the people of the Jews in captivity, who were deprived of their rights and liberties, and of the comforts of life; and were like dead men in their graves, to whom they are compared, Ezekiel 37:11; but since Jeremiah was not dead, nor did he die in the dungeon, Jarchi's sense seems best, and agrees with what follows; and is confirmed by the version of others, who render it, "they shut up my life in the dungeon" (q); or himself there:
and cast a stone upon me; to see if he was dead, or to prevent him from rising. The allusion is to the putting of stones at the mouths of dens and dungeons, caves and graves, to keep in those there put: or they stoned me, as the Targum; that is, they endeavoured to do it: or the Jews in captivity were like persons stoned to death, or like dead men covered with a heap of stones; for that Jeremiah was stoned to death there is no reason to believe.

in . . . dungeon-- (Jeremiah 37:16).
stone--usually put at the mouth of a dungeon to secure the prisoners (Joshua 10:18; Daniel 6:17; Matthew 27:60).

צמתוּ is here used transitively in Kal, as the Piel is elsewhere, Psalm 119:139, and the Pilpel, Psalm 88:17. צמתוּ בבּור, "they were destroying (cutting off) my life down into the pit," is a pregnant construction, and must be understood de conatu: "they sought to destroy my life when they hurled me down into the pit, and cast stones on me," i.e., not "they covered the pit with a stone" (Pareau, De Wette, Neumann). The verb ידה construed with בּ does not take this meaning, for ידה merely signifies to cast, e.g., lots (Joshua 4:3, etc.), arrows (Jeremiah 50:14), or to throw down = destroy, annihilate, Zac 2:4; and בּי does not mean "in the pit in which I was," but "upon (or against) me." The sing. אבן is to be understood in accordance with the expression רגם אבן, to cast stones = stone (1-Kings 12:18; Leviticus 20:2, Leviticus 20:27). As to ויּדּוּ for ויידּוּ, see on ויּגּה in Lamentations 3:33. "Waters flowed over my head" is a figurative expression, denoting such misery and distress as endanger life; cf. Psalm 59:2-3, Psalm 59:15., Psalm 124:4., Psalm 42:8. 'I said (thought), I am cut off (from God's eyes or hand)," Psalm 31:23; Psalm 88:6, is a reminiscence from these Psalm, and does not essentially differ from "cut off out of the land of the living," Isaiah 43:8. For, that we must thereby think of death, or sinking down into Sheol, is shown by מבּור תּחתּיּות, Lamentations 3:55. The complaint in these verses (52-54) is regarded by some expositors as a description of the personal sufferings of Jeremiah; and the casting into the pit is referred to the incident mentioned in Jeremiah 38:6. Such is the view, for instance, taken by Vaihinger and Ngelsbach, who point for proof to these considerations especially: (1) That the Chaldeans certainly could not, without good cause (Lamentations 3:53), be understood as the "enemies;" (2) that Jeremiah could not represent the people, speaking as if they were righteous and innocent; and (3) that the writer already speaks of his deliverance from their power, and contents himself with merely calling down on them the vengeance of God (Lamentations 3:55-66). But not one of these reasons is decisive. For, in the first place, the contents of Lamentations 3:52 do not harmonize with the known hostility which Jeremiah had to endure from his personal enemies. That is to say, there is nothing mentioned or known of his enemies having stoned him, or having covered him over with a stone, after they had cast him into the miry pit (Jeremiah 38:6.), The figurative character of the whole account thus shows itself in the very fact that the separate portions of it are taken from reminiscences of passages in the Psalm, whose figurative character is universally acknowledged. Moreover, in the expression איבי חנּם, even when we understand thereby the Chaldeans, it is not at all implied that he who complains of these enemies considers himself righteous and innocent, but simply that he has not given them any good ground for their hostile conduct towards him. And the assertion, that the writer is already speaking of his deliverance from their power, rests on the erroneous notion that, in Lamentations 3:55-66, he is treating of past events; whereas, the interchange of the perfects with imperatives of itself shows that the deliverance of which he there speaks is not an accomplished or bygone fact, but rather the object of that assured faith which contemplates the non-existent as existent. Lastly, the contrast between personal suffering ad the suffering of the people, on which the whole reasoning rests, is quite beside the mark. Moreover, if we take the lamentations to be merely symbolical, then the sufferings and persecutions of which the prophet here complains are not those of the people generally, but of the godly Israelites, on whom they were inflicted when the kingdom was destroyed, not merely by the Chaldeans, but also by their godless fellow-countrymen. Hence we cannot, of course, say that Jeremiah here speaks from personal experience; however, he complains not merely of the persecutions that befall him personally, but also of the sufferings that had come on him and all godly ones. The same remark applies to the conclusion of this lamentation, - the prayer, Lamentations 3:55-66, in which he entreats the Lord for deliverance, and in the spirit of faith views this deliverance as already accomplished.

Dungeon - Dungeon seems here to be taken for the lowest condition of misery.
