Jeremiah 38:4-6

4The officials then said to the king, “This man ought to die, because he is weakening the morale of the warriors who remain in this city and of all the people by speaking to them in this way. This man is not pursuing the welfare of this people, but their harm.”

5King Zedekiah said, “Here he is; he’s in your hands since the king can’t do anything against you.”

6So 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.
