1 Kings 20:39-41

39As the king was passing 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 another man to me and said, ‘Guard this man! If by any means he is missing, then your life will be for his life, or else you will weigh out a talent of silver.’

40Then as your servant was busy here and there, he was gone.” The king of Israel said to him, “So will your sentence be—you yourself have decided it.”

41Then he quickly took the headband away from his eyes, and the king of Israel recognized him as one of the prophets.
