Jeremiah 38:8

Then took they Jeremiah, and cast him into the dungeon of Malchiah the son of Hammelech, that was in the court of the prison: and they let down Jeremiah with cords. And in the dungeon there was no water, but mire: so Jeremiah sunk in the mire.

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;

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.
