Deuteronomy 8:10-18

And thou shalt eat and be full, and thou shalt bless Jehovah thy God for the good land which he hath given thee. Beware lest thou forget Jehovah thy God, in not keeping his commandments, and his ordinances, and his statutes, which I command thee this day: lest, when thou hast eaten and art full, and hast built goodly houses, and dwelt therein; and when thy herds and thy flocks multiply, and thy silver and thy gold is multiplied, and all that thou hast is multiplied; then thy heart be lifted up, and thou forget Jehovah thy God, who brought thee forth out of the land of Egypt, out of the house of bondage; who led thee through the great and terrible wilderness, wherein were fiery serpents and scorpions, and thirsty ground where was no water; who brought thee forth water out of the rock of flint; who fed thee in the wilderness with manna, which thy fathers knew not; that he might humble thee, and that he might prove thee, to do thee good at thy latter end: and lest thou say in thy heart, My power and the might of my hand hath gotten me this wealth. But thou shalt remember Jehovah thy God, for it is he that giveth thee power to get wealth; that he may establish his covenant which he sware unto thy fathers, as at this day.
