Dungeon. Literally, “pit,” or “cistern.” Malchiah is probably the one mentioned in v. 1. Hammelech means “the king.” Malchiah probably was “the son of the king” in the sense that he was a member of the royal house (see on ch. 36:26).
No water, but mire. Either the water of the cistern had been cut off because of the siege or this may have been in October or November, when there would be little water left after the dry season (see Vol. II, p. 110). At any rate, nothing but a deposit of foul mud remained in the cistern. Evidently the princes feared the effect upon the people if they publicly executed Jeremiah (see on vs. 4, 5). Therefore the prophet was lowered into the cistern to remain there until he died of starvation (v. 9). It is very likely that in Lam. 3:53-55 Jeremiah is referring to this time of misery and suffering.
