Deuteronomy 8:3-5

Revised Standard Version Catholic Edition

³ And he humbled you and let you hunger and fed you with manna, which you did not know, nor did your fathers know; that he might make you know that man does not live by bread alone, but that man lives by everything that proceeds out of the mouth of the Lord. ⁴ Your clothing did not wear out upon you, and your foot did not swell, these forty years. ⁵ Know then in your heart that, as a man disciplines his son, the Lord your God disciplines you.
