Deuteronomy 18:20-22 If you wonder, ‘How shall we know whether the prophecy is from the Lord or not?’
This is the way to know: If the thing he prophesies doesn’t happen, it is not the Lord who has given him the message; he has made it up himself. You have nothing to fear from him.
But any prophet who falsely claims that his message is from me, shall die. And any prophet who claims to give a message from other gods must die. Amen.
