Deuteronomy 8:2-16

Remember how the LORD your God has led you in the desert for these forty years, taking away your pride and testing you, because he wanted to know what was in your heart. He wanted to know if you would obey his commands. He took away your pride when he let you get hungry, and then he fed you with manna, which neither you nor your ancestors had ever seen. This was to teach you that a person does not live on bread alone, but by everything the LORD says. During these forty years, your clothes did not wear out, and your feet did not swell. Know in your heart that the LORD your God corrects you as a parent corrects a child. Obey the commands of the LORD your God, living as he has commanded you and respecting him. The LORD your God is bringing you into a good land, a land with rivers and pools of water, with springs that flow in the valleys and hills, a land that has wheat and barley, vines, fig trees, pomegranates, olive oil, and honey. It is a land where you will have plenty of food, where you will have everything you need, where the rocks are iron, and where you can dig copper out of the hills. When you have all you want to eat, then praise the LORD your God for giving you a good land. Be careful not to forget the LORD your God so that you fail to obey his commands, laws, and rules that I am giving to you today. When you eat all you want and build nice houses and live in them, when your herds and flocks grow large and your silver and gold increase, when you have more of everything, then your heart will become proud. You will forget the LORD your God, who brought you out of the land of Egypt, where you were slaves. He led you through the large and terrible desert that was dry and had no water, and that had poisonous snakes and stinging insects. He gave you water from a solid rock and manna to eat in the desert. Manna was something your ancestors had never seen. He did this to take away your pride and to test you, so things would go well for you in the end.
