Jeremiah 38:5–6

5 King Zedekiah said, “Here he is; he’s in your hands since the king can’t do anything against you.” 6 So they took Jeremiah and dropped him into the cistern of Malchiah the king’s son, which was in the guard’s courtyard, lowering Jeremiah with ropes. There was no water in the cistern, only mud, and Jeremiah sank in the mud.a
