'Falsehood' in the Bible

and he saith, I go out, and have become a spirit of falsehood in the mouth of all his prophets. And He saith, Thou dost entice, and also, thou art able; go out and do so.

And, now, lo, Jehovah hath put a spirit of falsehood in the mouth of these thy prophets, and Jehovah hath spoken concerning thee -- evil.'
