Deuteronomy 8:14

11 Beware lest thou forget Jehovah thy God, in not keeping his commandments, and his ordinances, and his statutes, which I command thee this day:

12 lest, when thou hast eaten and art full, and hast built goodly houses, and dwelt therein;

13 and when thy herds and thy flocks multiply, and thy silver and thy gold is multiplied, and all that thou hast is multiplied;

14 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;

15 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;

16 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:

17 and [lest] thou say in thy heart, My power and the might of my hand hath gotten me this wealth.
