Deuteronomy 8:3-13

3 He humbled you, and allowed you to hunger, and fed you with manna, which you didn't know, neither did your fathers know; that he might make you know that man does not live by bread only, but by everything that proceeds out of the mouth of the LORD does man live.
4 Your clothing didn't grow old on you, neither did your foot swell, these forty years.
5 You shall consider in your heart that as a man chastens his son, so the LORD your God chastens you.
6 You shall keep the mitzvot of the LORD your God, to walk in his ways, and to fear him.
7 For the LORD your God brings you into a good land, a land of brooks of water, of springs and springs, flowing forth in valleys and hills;
8 a land of wheat and barley, and vines and fig trees and pomegranates; a land of olive trees and honey;
9 a land in which you shall eat bread without scarceness, you shall not lack anything in it; a land whose stones are iron, and out of whose hills you may dig copper.
10 You shall eat and be full, and you shall bless the LORD your God for the good land which he has given you.
11 Beware lest you forget the LORD your God, in not keeping his mitzvot, and his ordinances, and his statutes, which I command you this day:
12 lest, when you have eaten and are full, and have built goodly houses, and lived therein;
13 and when your herds and your flocks multiply, and your silver and your gold is multiplied, and all that you have is multiplied;
