19. "The prophet will speak in my name. But someone might not listen to what I say through the prophet. Then that person will be accountable to me.
20. "But suppose a prophet dares to speak in my name something I have not commanded him to say. Or he speaks in the name of other gods. Then that prophet must be put to death."
21. You will say to yourselves, "How can we know when a message hasn't been spoken by the Lord?"
