Jeremiah 23:14-17, 31-32

In the prophets of Jerusalem also I have seen a horrible thing: they commit adultery, and walk in lies; and they strengthen the hands of evil-doers, so that none doth return from his wickedness: they are all of them become unto me as Sodom, and the inhabitants thereof as Gomorrah. Therefore thus saith Jehovah of hosts concerning the prophets: Behold, I will feed them with wormwood, and make them drink the water of gall; for from the prophets of Jerusalem is ungodliness gone forth into all the land. 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. They say continually unto them that despise me, Jehovah hath said, Ye shall have peace; and unto every one that walketh in the stubbornness of his own heart they say, No evil shall come upon you.

Behold, I am against the prophets, saith Jehovah, that use their tongues, and say, He saith. Behold, I am against them that prophesy lying dreams, saith Jehovah, and do tell them, and cause my people to err by their lies, and by their vain boasting: yet I sent them not, nor commanded them; neither do they profit this people at all, saith Jehovah.
