1 Kings 20:39-41

39And as the king passed, he cried to the king and said, "Your servant went out into the midst of the battle, and behold, a soldier turned and brought a man to me and said, 'Guard this man; if by any means he is missing, your life shall be for his life, or else you shall pay a talent of silver.'

40And as your servant was busy here and there, he was gone." The king of Israel said to him, "So shall your judgment be; you yourself have decided it."

41Then he hurried to take the bandage away from his eyes, and the king of Israel recognized him as one of the prophets.
