Deuteronomy 8:15-18

15who led you through that great and terrible wilderness, in which were fiery serpents and scorpions and thirsty land where there was no water; who brought water for you out of the flinty rock;

16who fed you in the wilderness with manna, which your fathers did not know, that He might humble you and that He might test you, to do you good in the end—

17then you say in your heart, ‘My power and the might of my hand have gained me this wealth.’

18“And you shall remember the Lord 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 it is this day.
