Deuteronomy 8:19-20

Young's Literal Translation

¹⁹ `And it hath been -- if thou really forget Jehovah thy God, and hast gone after other gods, and served them, and bowed thyself to them, I have testified against you to-day that ye do utterly perish;

²⁰ as the nations whom Jehovah is destroying from your presence, so ye perish; because ye hearken not to the voice of Jehovah your God.
