1 Kings 22:21 Meaning

19And 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.

20And 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.

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

22And 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.

23Now therefore, behold, the LORD hath put a lying spirit in the mouth of all these thy prophets, and the LORD hath spoken evil concerning thee.
