1 Kings 22:18-22

And the king of Israel said unto Jehoshaphat, Did I not tell thee that he would prophesy no good concerning me, but evil?

And he said, Hear thou therefore the word of the LORD: I saw the LORD sitting on his throne, and all the host of heaven standing by him on his right hand and on his left.

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.
