Jeremiah 38:4-6

38:4 So these officials said to the king, “This man must be put to death. For he is demoralizing the soldiers who are left in the city as well as all the other people there by these things he is saying. This man is not seeking to help these people but is trying to harm them.” 38:5 King Zedekiah said to them, “Very well, you can do what you want with him. For I cannot do anything to stop you.” 38:6 So the officials took Jeremiah and put him in the cistern of Malkijah, one of the royal princes, that was in the courtyard of the guardhouse. There was no water in the cistern, only mud. So when they lowered Jeremiah into the cistern with ropes he sank in the mud.
