Jeremiah 14:14

14:14 Then the LORD said unto me, The prophets prophesy lies in my name: I sent them not, neither have I commanded them, neither spake unto them: they prophesy unto you a false vision and divination, and a thing of nought, and the deceit of their heart.

Matthew 7:15

7:15 Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.
