Jeremiah 38:4-6, 27

These officials told the king, “Please, kill this man. He’s got to go! He’s ruining the resolve of the soldiers who are still left in the city, as well as the people themselves, by spreading these words. This man isn’t looking after the good of this people. He’s trying to ruin us!” King Zedekiah caved in: “If you say so. Go ahead, handle it your way. You’re too much for me.” So they took Jeremiah and threw him into the cistern of Malkijah the king’s son that was in the courtyard of the palace guard. They lowered him down with ropes. There wasn’t any water in the cistern, only mud. Jeremiah sank into the mud.

And sure enough, all the officials came to Jeremiah and asked him. He responded as the king had instructed. So they quit asking. No one had overheard the conversation.
