Jeremiah 38:9-10

“My lord the king, all these terrible things these men have done to Jeremiah the prophet are evil. They've put him in the cistern, and he'll starve to death there because there's no more bread left in the city.” So the king gave the order to Ebed-melech the Cushite, “Take thirty men with you and go and pull Jeremiah the prophet out of the cistern before he dies.”
