I Kings 22:20-22

And the LORD said, ‘Who will persuade Ahab to go up, that he may fall at Ramoth Gilead?’ So one spoke in this manner, and another spoke in that manner. Then a spirit came forward and stood before the LORD, and said, ‘I will persuade him.’ The LORD said to him, ‘In what way?’ So he said, ‘I will go out and be a lying spirit in the mouth of all his prophets.’ And the LORD said, ‘You shall persuade him, and also prevail. Go out and do so.’
