1 Kings 20:40-44

And 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.

And he hasted, and took the ashes away from his face; and the king of Israel discerned him that he was of the prophets.

And he said unto him, Thus saith the LORD, Because thou hast let go out of thy hand a man whom I appointed to utter destruction, therefore thy life shall go for his life, and thy people for his people.

And the king of Israel went to his house heavy and displeased, and came to Samaria.
