Jeremiah 23:16, 21-22

Thus saith Jehovah of hosts, Hearken not unto the words of the prophets that prophesy unto you: they teach you vanity; they speak a vision of their own heart, and not out of the mouth of Jehovah.

I sent not these prophets, yet they ran: I spake not unto them, yet they prophesied. But if they had stood in my council, then had they caused my people to hear my words, and had turned them from their evil way, and from the evil of their doings.
