Jeremiah 38:6; Jeremiah 38:9

6 Then they took Jeremiah and cast him into the cistern of Malchijah the king's son, which was in the court of the guardhouse; and they let Jeremiah down with ropes. Now in the cistern there was no water but only mud, and Jeremiah sank into the mud.

9 "My lord the king, these men have acted wickedly in all that they have done to Jeremiah the prophet whom they have cast into the cistern; and he will die right where he is because of the famine, for there is no more bread in the city."
