Ezekiel 13:2-3, 23

“Son of man, prophesy against the prophets of Israel, who are prophesying, and say to those who prophesy from their own hearts: ‘Hear the word of the LORD!’ Thus says the Lord GOD, Woe to the foolish prophets who follow their own spirit, and have seen nothing!

therefore you shall no more see false visions nor practice divination. I will deliver my people out of your hand. And you shall know that I am the LORD.”
