Deuteronomy 8:9-14, 17-18

a land where you will eat bread without shortage, in which you will lack nothing; a land whose stones are iron, and out of whose hills you can dig copper. When you have eaten and are satisfied, then you shall bless the LORD your God for the good land which He has given you. “Beware that you do not forget the LORD your God by failing to keep His commandments and His judgments (precepts) and His statutes which I am commanding you today; otherwise, when you have eaten and are satisfied, and have built good houses and lived in them, and when your herds and flocks multiply, and your silver and gold multiply, and all that you have increases, then your heart will become lifted up [by self-conceit and arrogance] and you will forget the LORD your God who brought you from the land of Egypt, out of the house of slavery.

Otherwise, you may say in your heart, ‘My power and the strength of my hand made me this wealth.’ But you shall remember [with profound respect] the LORD your God, for it is He who is giving you power to make wealth, that He may confirm His covenant which He swore (solemnly promised) to your fathers, as it is this day.
