I Kings 20:38-41

Then the prophet departed and waited for the king by the road, and disguised himself with a bandage over his eyes. Now as the king passed by, he cried out to the king and said, “Your servant went out into the midst of the battle; and there, a man came over 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.’ While your servant was busy here and there, he was gone.” Then the king of Israel said to him, “So shall your judgment be; you yourself have decided it.” And he hastened to take the bandage away from his eyes; and the king of Israel recognized him as one of the prophets.
