Deuteronomy 8:1-2

New Revised Standard Version, Anglicised Catholic Edition

A Warning Not to Forget God in Prosperity

8 This entire commandment that I command you today you must diligently observe, so that you may live and increase, and go in and occupy the land that the Lord promised on oath to your ancestors. ² Remember the long way that the Lord your God has led you these forty years in the wilderness, in order to humble you, testing you to know what was in your heart, whether or not you would keep his commandments.
