Jeremiah 38:4-6, 27

Therefore the princes said to the king, “Please, let this man be put to death, for thus he weakens the hands of the men of war who remain in this city, and the hands of all the people, by speaking such words to them. For this man does not seek the welfare of this people, but their harm.” Then Zedekiah the king said, “Look, he is in your hand. For the king can do nothing against you.” So they took Jeremiah and cast him into the dungeon of Malchiah the king’s son, which was in the court of the prison, and they let Jeremiah down with ropes. And in the dungeon there was no water, but mire. So Jeremiah sank in the mire.

Then all the princes came to Jeremiah and asked him. And he told them according to all these words that the king had commanded. So they stopped speaking with him, for the conversation had not been heard.
