Jeremiah 38:9-10; Jeremiah 38:14
"My lord the king, these men have done evil in all that they did to Jeremiah the prophet by casting him into the cistern, and he will die there of hunger, for there is no bread left in the city."
Then the king commanded Ebed-melech the Ethiopian, "Take thirty men with you from here, and lift Jeremiah the prophet out of the cistern before he dies."
King Zedekiah sent for Jeremiah the prophet and received him at the third entrance of the temple of the LORD. The king said to Jeremiah, "I will ask you a question; hide nothing from me."
