Jeremiah 39:16

Now when Ebedmelech the Ethiopian, one of the eunuchs which was in the king's house, heard that they had put Jeremiah in the dungeon; the king then sitting in the gate of Benjamin; Ebedmelech went forth out of the king's house, and spake to the king saying, My lord the king, these men have done evil in all that they have done to Jeremiah the prophet, whom they have cast into the dungeon; and he is like to die for hunger in the place where he is: for there is no more bread in the city. Then the king commanded Ebedmelech the Ethiopian, saying, Take from hence thirty men with thee, and take up Jeremiah the prophet out of the dungeon, before he die. So Ebedmelech took the men with him, and went into the house of the king under the treasury, and took thence old cast clouts and old rotten rags, and let them down by cords into the dungeon to Jeremiah. And Ebedmelech the Ethiopian said unto Jeremiah, Put now these old cast clouts and rotten rags under thine armholes under the cords. And Jeremiah did so. So they drew up Jeremiah with cords, and took him up out of the dungeon: and Jeremiah remained in the court of the prison.
