Jeremiah 38:4-6

4 Therefore the princes said to the king, We beseech you, let this man be put to death: for thus he weakens the hands of the men of war that remain in this city, and the hands of all the people, in speaking such words to them: for this man seeks not the welfare of this people, but the hurt.

5 Then Zedekiah the king said, Behold, he is in your hand: for the king is not he that can do any thing against you.

6 Then took they Jeremiah, and cast him into the dungeon of Malchiah the son of Hammelech, that was in the court of the prison: and they let down Jeremiah with cords. And in the dungeon there was no water, but mire: so Jeremiah sunk in the mire.
