Jeremiah 23:16, 21-22

Thus saith the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD.

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