1 Kings 22:21-23

21And there came forth a spirit, and stood before the LORD, and said, I will persuade him. 22And the LORD said to him, How? And he said, I will go forth, and I will be a lying spirit in the mouth of all his prophets. And he said, Thou shalt persuade him, and prevail also: go forth, and do so. 23Now therefore, behold, the LORD hath put a lying spirit in the mouth of all these thy prophets, and the LORD hath spoken evil concerning thee.
