1 Kings 20:39-41

39As the king passed by, he cried out to the king: “Your servant had marched out into the middle of the battle, when suddenly a man came over with a captive and told me, ‘Guard this man! If he goes missing for any reason, your life will be exchanged for his life, or you will weigh out a talent of silver.1’ 40But while your servant was busy here and there, the man disappeared.”

And the king of Israel said to him, “So shall your judgment be; you have pronounced it on yourself.”

41Then the prophet quickly removed the bandage from his eyes, and the king of Israel recognized him as one of the prophets.
