Hammelech

The king commanded Jerahmeel the king’s son, and Seraiah the son of Azriel, and Shelemiah the son of Abdeel, to take Baruch the scribe and Jeremiah the prophet; but the LORD hid them.

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. In the dungeon there was no water, but mire; and Jeremiah sank in the mire.
