Deuteronomy 8:19-20

New Revised Standard Version, Anglicised Catholic Edition

¹⁹ If you do forget the Lord your God and follow other gods to serve and worship them, I solemnly warn you today that you shall surely perish. ²⁰ Like the nations that the Lord is destroying before you, so shall you perish, because you would not obey the voice of the Lord your God.
