Deuteronomy 8:1-3 Revised Standard Version (RSV)
A Warning Not to Forget God in Prosperity
8 “All the commandment which I command you this day you shall be careful to do, that you may live and multiply, and go in and possess the land which the Lord swore to give to your fathers. 2 And you shall remember all the way which the Lord your God has led you these forty years in the wilderness, that he might humble you, testing you to know what was in your heart, whether you would keep his commandments, or not. 3 And he humbled you and let you hunger and fed you with manna, which you did not know, nor did your fathers know; that he might make you know that man does not live by bread alone, but that man lives by everything that proceeds out of the mouth of the Lord.
