1 Kings 20:40-42

40And as thy servant was busy here and there, he was gone. And the king of Israel said unto him, So shall thy judgment be; thyself hast decided it. 41And he hasted, and took the headband away from his eyes; and the king of Israel discerned him that he was of the prophets. 42And he said unto him, Thus saith Jehovah, Because thou hast let go out of thy hand the man whom I had devoted to destruction, therefore thy life shall go for his life, and thy people for his people.
