Deuteronomy 8:18-20

New American Standard Bible

¹⁸ But you are to remember the Lord your God, for ^(A)it is He who is giving you power to make wealth, in order to confirm His covenant which He swore to your fathers, as it is this day. ¹⁹ And it shall come about, if you ever forget the Lord your God and follow other gods and serve and worship them, ^(B)I testify against you today that you will certainly perish. ²⁰ Like the nations that the Lord eliminates from you, so ^(C)you shall perish, because you would not listen to the voice of the Lord your God.
