I Kings 22:21-23

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.’ Therefore look! The LORD has put a lying spirit in the mouth of all these prophets of yours, and the LORD has declared disaster against you.”
