Deuteronomy 8:2-4

BBE(i) 2 And keep in mind the way by which the Lord your God has taken you through the waste land these forty years, so that he might make low your pride and put you to the test, to see what was in your heart and if you would keep his orders or not. 3 And he made low your pride and let you be without food and gave you manna for your food, a thing new to you, which your fathers never saw; so that he might make it clear to you that bread is not man's only need, but his life is in every word which comes out of the mouth of the Lord. 4 Through all these forty years your clothing did not get old or your feet become tired.
