Deuteronomy 18:20-22

“But any prophet who fakes it, who claims to speak in my name something I haven’t commanded him to say, or speaks in the name of other gods, that prophet must die.” You may be wondering among yourselves, “How can we tell the difference, whether it was GOD who spoke or not?” Here’s how: If what the prophet spoke in GOD’s name doesn’t happen, then obviously GOD wasn’t behind it; the prophet made it up. Forget about him. * * *
