Deuteronomy 18:21-22

Revised Geneva Translation

²¹ “And if you think in your heart, ‘How shall we know the word which the LORD has not spoken?’

²² “When a prophet speaks in the Name of the LORD, if the thing does not follow or happen, that is the thing which the LORD has not spoken. The prophet has spoken it presumptuously. You shall not be afraid of him.”
