Deuteronomy 8:15

12 lest, when you have eaten and are full, and have built goodly houses, and lived therein;

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

14 then your heart be lifted up, and you forget Yahweh your God, who brought you forth out of the land of Egypt, out of the house of bondage;

15 who led you through the great and terrible wilderness, [in which were] fiery serpents and scorpions, and thirsty ground where was no water; who brought you forth water out of the rock of flint;

16 who fed you in the wilderness with manna, which your fathers didn`t know; that he might humble you, and that he might prove you, to do you good at your latter end:

17 and [lest] you say in your heart, My power and the might of my hand has gotten me this wealth.

18 But you shall remember Yahweh your God, for it is he who gives you power to get wealth; that he may establish his covenant which he swore to your fathers, as at this day.
