Deuteronomy 8:3-5

New Life Version

³ He let you be hungry which helped you to not have pride. Then He fed you with bread from heaven which you and your fathers had not known. He did this to make you understand that man does not live by bread alone. But man lives by everything that comes out of the mouth of the Lord. ⁴ Your clothes did not wear out, and your feet did not get sore during these forty years. ⁵ So know in your heart that the Lord your God was punishing you just as a man punishes his son.
