Deuteronomy 8:11-18

"Take heed lest you forget the LORD your God, by not keeping his commandments and his ordinances and his statutes, which I command you this day: lest, when you have eaten and are full, and have built goodly houses and live in them, and when your herds and flocks multiply, and your silver and gold is multiplied, and all that you have is multiplied, then your heart be lifted up, and you forget the LORD your God, who brought you out of the land of Egypt, out of the house of bondage, who led you through the great and terrible wilderness, with its fiery serpents and scorpions and thirsty ground where there was no water, who brought you water out of the flinty rock, who fed you in the wilderness with manna which your fathers did not know, that he might humble you and test you, to do you good in the end. "Beware lest you say in your heart, 'My power and the might of my hand have gotten me this wealth.' You shall remember the LORD your God, for it is he who gives you power to get wealth; that he may confirm his covenant which he swore to your fathers, as at this day."
