Jeremiah 38:9-10

“My lord the king, these men have acted wickedly in all that they have done to Jeremiah the prophet whom they have thrown into the cistern; and he will die [of hunger] where he is because of the famine, for there is no more bread in the city.” Then the king commanded Ebed-melech the Ethiopian, saying, “Take thirty men from here with you and lift Jeremiah the prophet out of the cistern before he dies.”
