1 Kings 22:20-22

20And Yhwh 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.1

21And there came forth a spirit, and stood before Yhwh, and said, I will persuade him.

22And Yhwh 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.
