Deuteronomy 18:20-22

Common English Bible

²⁰ However, any prophet who arrogantly speaks a word in my name that I haven’t commanded him to speak, or who speaks in the name of other gods—that prophet must die.

²¹ Now, you might be wondering, How will we know which word God hasn’t spoken? ²² Here’s the answer: The prophet who speaks in the Lord’s name and the thing doesn’t happen or come about—that’s the word the Lord hasn’t spoken. That prophet spoke arrogantly. Don’t be afraid of him.^[a]
