Jeremiah 38:6

Amplified Bible, Classic Edition

⁶ So they took Jeremiah and cast him into the dungeon or cistern pit [in the charge] of Malchiah the king’s son, which was in the court of the guard; and they let Jeremiah down [into the pit] with ropes. And in the dungeon or cistern pit there was no water, but only mire, and Jeremiah sank in the mire.
