Jeremiah 29:8

“I have heard what the prophets have said who prophesy a lie in My name, saying, ‘I had a dream, I had a dream!’

who intend to make My people forget My name by their dreams which they recount to one another, just as their fathers forgot My name because of Baal?

“So do not listen to the words of the prophets who speak to you, saying, ‘You will not serve the king of Babylon,’ for they prophesy a lie to you;

“Thus says Yahweh of hosts, the God of Israel, concerning Ahab the son of Kolaiah and concerning Zedekiah the son of Maaseiah, who are prophesying to you falsely in My name, ‘Behold, I will give them into the hand of Nebuchadnezzar king of Babylon, and he will strike them down before your eyes.

because they have acted with wicked foolishness in Israel and have committed adultery with their neighbors’ wives and have spoken words in My name falsely, which I did not command them; and I am He who knows and am a witness,” declares Yahweh.’”

“Thus says Yahweh, ‘Do not deceive yourselves, saying, “The Chaldeans will surely go away from us,” for they will not go.

Your prophets have beheld for you Worthless and ineffective visions; And they have not uncovered your iniquity So as to return you from captivity, But they have beheld for you worthless and misleading oracles.

“They behold worthlessness and lying divination who are saying, ‘Yahweh declares,’ when Yahweh has not sent them; yet they wait for the establishing of their word.

And Jesus answered and said to them, “See to it that no one deceives you.

Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.
