Deuteronomy 8:18-20

“And you shall remember the LORD your God, for it is He who gives you power to get wealth, that He may establish His covenant which He swore to your fathers, as it is this day. Then it shall be, if you by any means forget the LORD your God, and follow other gods, and serve them and worship them, I testify against you this day that you shall surely perish. As the nations which the LORD destroys before you, so you shall perish, because you would not be obedient to the voice of the LORD your God.
