Deuteronomy 8:1-3

Living Bible

8 “You must obey all the commandments I give you today. If you do, you will not only live, you will multiply and will go in and take over the land promised to your fathers by the Lord. ² Do you remember how the Lord led you through the wilderness for all those forty years, humbling you and testing you to find out how you would respond, and whether or not you would really obey him? ³ Yes, he humbled you by letting you go hungry and then feeding you with manna, a food previously unknown to both you and your ancestors. He did it to help you realize that food isn’t everything, and that real life comes by obeying every command of God.
