Deuteronomy 8:17–19

and lest you say in your heart, “My power and the might of my hand has gotten me this wealth.” But 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 today. It shall be, if you shall forget the LORD your God, and walk after other gods, and serve them and worship them, I testify against you today that you shall surely perish.
