'Lying Spirit' in the Bible

And the LORD said to him, With what? 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.

Now 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.
