Deuteronomy 8:12-14

Then you will have plenty to eat, and you will build good houses and live in them. Your cattle, sheep, and goats will grow large. You will get plenty of gold and silver. You will have plenty of everything. When that happens, you must be careful not to become proud. You must not forget the LORD your God. You were slaves in Egypt, but he made you free and brought you out of that land.
