1 Kings 22:20-22

And the LORD said, Who shall persuade Ahab, that he may go up and fall at Ramoth-gilead? And one said on this manner, and another said on that manner. And there came forth a spirit, and stood before the LORD, and said, I will persuade him. 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.
