1 Kings 20:38-41

So the prophet departed and waited for the king by the way, and disguised himself with a bandage over his eyes. As the king passed by, he cried to the king and said, “Your servant went out into the midst 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 for his life, or else you shall pay a talent of silver.’ While your servant was busy here and there, he was gone.” And the king of Israel said to him, “So shall your judgment be; you yourself have decided it.” Then he hastily took the bandage away from his eyes, and the king of Israel recognized him that he was of the prophets.
