Jeremiah 38:11

So Ebed-melech took the men with him and went into the house of the king under the treasury, to a room which was evidently used for storage purposes, and took thence old cast clouts and old rotten rags, remnants of cast-off and worn-out garments of every description, and let them down by cords into the dungeon to Jeremiah. Ebed-melech evidently possessed both presence of mind and resourcefulness, for he lost no time in beginning his work of rescuing the prophet.
