1 Kings 20:39-42

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.

42And he said to him, "Thus says the Lord, 'Because you have let go out of your hand the man whom I had devoted to destruction, therefore your life shall be for his life, and your people for his people.'"
