Deuteronomy 8:2–5

2 “aYou shall remember all the way which the Lord your God has bled you in the wilderness these forty years, that He might humble you, ctesting you, to know what was in your heart, whether you would keep His commandments or not.

3 “He humbled you and let you be hungry, and fed you with manna which you did not know, nor did your fathers know, that He might make you 1understand that aman does not live by bread alone, but man lives by everything that proceeds out of the mouth of the Lord.

4 “aYour clothing did not wear out on you, nor did your foot swell these forty years.

5 “aThus you are to know in your heart that the Lord your God was disciplining you just as a man disciplines his son.
