Jeremiah 38:6, 10-13

Then took they Jeremiah, and cast him into the dungeon of Malchijah the king’s son, that was in the court of the guard: and they let down Jeremiah with cords. And in the dungeon there was no water, but mire; and Jeremiah sank in the mire.

Then the king commanded Ebed-melech the Ethiopian, saying, Take from hence thirty men with thee, and take up Jeremiah the prophet out of the dungeon, before he die. So Ebed-melech took the men with him, and went into the house of the king under the treasury, and took thence rags and worn-out garments, and let them down by cords into the dungeon to Jeremiah. And Ebed-melech the Ethiopian said unto Jeremiah, Put now these rags and worn-out garments under thine armholes under the cords. And Jeremiah did so. So they drew up Jeremiah with the cords, and took him up out of the dungeon: and Jeremiah remained in the court of the guard.
