Deuteronomy 8:2-10

You are to remember all the way that ADONAI your God has led you these 40 years in the wilderness—in order to humble you, to test you, to know what was in your heart, whether you would keep His mitzvot or not. He afflicted you and let you hunger, then He fed you manna —which neither you nor your fathers had known—in order to make you understand that man does not live by bread alone but by every word that comes from the mouth of ADONAI. Neither did your clothing wear out on you, nor did your foot swell these 40 years. Now you know in your heart that as a man disciplines his son, so ADONAI your God disciplines you. So you are to keep the mitzvot of ADONAI your God—to walk in His ways and to fear Him. For ADONAI your God is bringing you into a good land—a land of wadis with water, of springs and fountains flowing out in the valleys and hills, a land of wheat and barley, vines, figs and pomegranates, a land of olive oil and honey, a land where you will eat bread with no poverty, where you will lack nothing, a land whose stones are iron, and out of whose hills you can dig copper. So you will eat and be full, and you will bless ADONAI your God for the good land He has given you.
