Deuteronomy 8:13

11Beware lest you forget the LORD your God, in not keeping his commandments, his ordinances, and his statutes, which I command you today;

12lest, when you have eaten and are full, and have built fine houses and lived in them;

13and when your herds and your flocks multiply, and your silver and your gold is multiplied, and all that you have is multiplied;

14then your heart might 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;

15who led you through the great and terrible wilderness, with venomous snakes and scorpions, and thirsty ground where there was no water; who poured water for you out of the rock of flint;
