Jeremiah 38:8

⁶  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.

⁷  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;

⁸  Ebedmelech went forth out of the king's house, and spake to the king saying,

⁹  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.

¹⁰  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.
