1 Kings 22:21-22King James Version (KJV)
21 And there came forth a spirit, and stood before the Lord, and said, I will persuade him.
22 And the Lord said unto him, Wherewith? 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.
