Jeremiah 38:4-6

4And the princes said unto the king, Let this man, we pray thee, be put to death; for why should he weaken the hands of the men of war that remain in this city, and the hands of all the people, in speaking to them according to these words? for this man seeketh not the welfare of this people, but the hurt.

5And king Zedekiah said, Behold, he is in your hand; for the king is not he that can do a thing against you.

6Then they took Jeremiah, and cast him into the dungeon of Malchijah the son of Hammelech, which was in the court of the guard, and they let down Jeremiah with cords. And in the dungeon there was no water, but mire; and Jeremiah sank in the mire.
