14Then thine heart be lifted up, and thou forget the LORD thy God, which brought thee forth out of the land of Egypt, from the house of bondage;
15Who led thee through that great and terrible wilderness, fiery serpents, and scorpions, and drought, where no water; who brought thee forth water out of the rock of flint;
16Who 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;
17And thou say in thine heart, My power and the might of hand hath gotten me this wealth.
18But thou shalt remember the LORD thy God: for he that giveth thee power to get wealth, that he may establish his covenant which he sware unto thy fathers, as this day.
19And it shall be, if thou do at all forget the LORD thy God, and walk after other gods, and serve them, and worship them, I testify against you this day that ye shall surely perish.
