Jeremiah 38:9-10

“My lord the king, these men have acted wickedly in all they have done to Jeremiah the prophet. They have thrown him into a cistern, where he will starve to death when there is no longer any bread in the city.” Then the king commanded Ebed-Melek the Cushite, “Take thirty men from here with you and lift Jeremiah the prophet out of the cistern before he dies.”
