Isaiah 9:15

For false Christs and false prophets will appear and perform great signs and wonders that would deceive even the elect, if that were possible.

For the LORD has poured out on you a spirit of deep sleep. He has shut your eyes, O prophets; He has covered your heads, O seers.

You have profaned Me among My people for handfuls of barley and scraps of bread. By lying to My people who would listen, you have killed those who should not have died and spared those who should not have lived.

“Look,” said the servant, “in this city there is a man of God who is highly respected; everything he says surely comes to pass. Let us go there now. Perhaps he will tell us which way to go.”

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

The prophet is Ephraim’s watchman, along with my God, yet the snare of the fowler lies on all his paths. Hostility is in the house of his God!

But the beast was captured along with the false prophet, who on its behalf had performed signs deceiving those who had the mark of the beast and worshiped its image. Both the beast and the false prophet were thrown alive into the fiery lake of burning sulfur.

Because you have disheartened the righteous with your lies, even though I have caused them no grief, and because you have encouraged the wicked not to turn from their evil ways to save their lives,

As for the prophets: My heart is broken within me, and all my bones tremble. I have become like a drunkard, like a man overcome by wine, because of the LORD, because of His holy words.

Beware of false prophets. They come to you in sheep’s clothing, but inwardly they are ravenous wolves.
