Jeremiah 38:8

6 So they took Jeremiah and dropped him into the cistern of Malchiah, the king’s son, which was in the courtyard of the guard. They lowered Jeremiah with ropes into the cistern, which had no water but only mud, and Jeremiah sank down into the mud.

7 Now Ebed-melech the Cushite, a court official in the royal palace, heard that Jeremiah had been put into the cistern. While the king was sitting at the Gate of Benjamin,

8 Ebed-melech went out from the king’s palace and said to the king,

9 “My lord the king, these men have acted wickedly in all that they have done to Jeremiah the prophet. They have dropped him into the cistern, where he will starve to death, for there is no more bread in the city.”

10 So the king commanded Ebed-melech the Cushite, “Take thirty men from here with you and pull Jeremiah the prophet out of the cistern before he dies.”
