Jeremiah 38:4-6, 27

So these officials went to the king and said, “Sir, this man must die! That kind of talk will undermine the morale of the few fighting men we have left, as well as that of all the people. This man is a traitor!” King Zedekiah agreed. “All right,” he said. “Do as you like. I can’t stop you.” So the officials took Jeremiah from his cell and lowered him by ropes into an empty cistern in the prison yard. It belonged to Malkijah, a member of the royal family. There was no water in the cistern, but there was a thick layer of mud at the bottom, and Jeremiah sank down into it.

Sure enough, it wasn’t long before the king’s officials came to Jeremiah and asked him why the king had called for him. But Jeremiah followed the king’s instructions, and they left without finding out the truth. No one had overheard the conversation between Jeremiah and the king.
