Deuteronomy 8:18-20

Douay-Rheims 1899 American Edition

¹⁸ But remember the Lord thy God, that he hath given thee strength, that he might fulfill his covenant, concerning which he swore to thy fathers, as this present day sheweth.

¹⁹ But if thou forget the Lord thy God, and follow strange gods, and serve and adore them: behold now I foretell thee that thou shalt utterly perish.

²⁰ As the nations, which the Lord destroyed at thy entrance, so shall you also perish, if you be disobedient to the voice of the Lord your God.
