Deuteronomy 8:18-20

American Standard Version

¹⁸ But thou shalt remember Jehovah thy God, for it is he that giveth thee power to get wealth; that he may establish his covenant which he sware unto thy fathers, as at this day. ¹⁹ And it shall be, if thou shalt forget Jehovah thy God, and walk after other gods, and serve them, and worship them, I testify against you this day that ye shall surely perish. ²⁰ As the nations that Jehovah maketh to perish before you, so shall ye perish; because ye would not hearken unto the voice of Jehovah your God.
