1 Kings 20:39-41

39As the king passed by, the prophet called out to the king and said, “Your servant went out into the middle of the battle, and behold, a man turned aside and brought a man to me and said, ‘Guard this man; if for any reason he is missing, then your life shall be required for his life, or else you shall pay a talent of silver.’

40But while your servant was busy here and there, he [escaped and] was gone.” And the king of Israel said to him, “Such is your own judgment (verdict); you have determined it.”

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