Deuteronomy 8:9-14, 17-18

It is a land where food is plentiful and nothing is lacking. It is a land where iron is as common as stone, and copper is abundant in the hills. When you have eaten your fill, be sure to praise the LORD your God for the good land he has given you. “But that is the time to be careful! Beware that in your plenty you do not forget the LORD your God and disobey his commands, regulations, and decrees that I am giving you today. For when you have become full and prosperous and have built fine homes to live in, and when your flocks and herds have become very large and your silver and gold have multiplied along with everything else, be careful! Do not become proud at that time and forget the LORD your God, who rescued you from slavery in the land of Egypt.

He did all this so you would never say to yourself, ‘I have achieved this wealth with my own strength and energy.’ Remember the LORD your God. He is the one who gives you power to be successful, in order to fulfill the covenant he confirmed to your ancestors with an oath.
