Jeremiah 38:4-6 King James Version (KJV)
4 Therefore the princes said unto the king, We beseech thee, let this man be put to death: for thus he weakeneth the hands of the men of war that remain in this city, and the hands of all the people, in speaking such words unto them: for this man seeketh 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.
