The Dungeon of Malchijah — Jeremiah 38:4–6
Then the princes said unto the king,
Let this man, we pray thee, be put to death; forasmuch as 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.
And Zedekiah the king said,
Behold, he is in your hand; for the king is not he that can do anything against you.
Then took they Jeremiah, and cast him into the dungeon of Malchijah the king's son, that 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.
