Deuteronomy 8:11-17

11“Take care lest you forget the LORD your God by not keeping his commandments and his rules and his statutes, which I command you today, 12lest, when you have eaten and are full and have built good houses and live in them, 13and when your herds and flocks multiply and your silver and gold is multiplied and all that you have is multiplied, 14then your heart be lifted up, and you forget the LORD your God, who brought you out of the land of Egypt, out of the house of slavery, 15who led you through the great and terrifying wilderness, with its fiery serpents and scorpions and thirsty ground where there was no water, who brought you water out of the flinty rock, 16who fed you in the wilderness with manna that your fathers did not know, that he might humble you and test you, to do you good in the end. 17Beware lest you say in your heart, ‘My power and the might of my hand have gotten me this wealth.’
