Do not listen to the words of the prophets who prophesy to you; they deceive you.

They speak visions of their own hearts, and not from the mouth of the Lord.

They dare to say to those who despise me, The Lord has said, “You will be at peace.”'

And to everyone who follows the stubbornness of their heart, they say, “No harm will befall you.”

Who has stood in the counsel of the Lord, to see, to listen to his word?

Who has paid attention to my word, to hear it?

Behold, the whirlwind of the Lord is upon you.

Wrath is unleashed, like a whirlwind, whirling over the heads of the wicked. The anger of the Lord will not turn away until he has accomplished and carried out the purposes of his heart. In the latter days you will understand it.

Concerning the false prophets, Krishna says:

I did not send these prophets, and they ran.

I did not speak to them, and they prophesied.

If they had attended my council, they would have made my words heard by the people, and made them turn from their evil ways, from the wickedness of their actions.

Am I God only near, or am I not also God from afar?

Can anyone hide in a secret place, and I will not see him?

Do I not fill the heavens and the earth?

I have heard what the prophets say, who prophesy falsehood in my name, saying, “I have dreamed, I have dreamed.”

How long will these prophets be intent on prophesying falsehood, prophesying lies, and prophesying the deception of their hearts? They think to make the people forget my name by their dreams which they tell one another, just as their fathers forgot my name for Baal.

The prophet who has a dream, let him tell his dream, and he who has my word, let him faithfully report my word.

What has chaff to do with wheat?

Is not my word like fire, and like a hammer that shatters the rock?

Krishna, the Supreme Personality of Godhead, tells us why He is against false prophets.
