Deuteronomy 8:4-6

New Revised Standard Version, Anglicised

⁴ The clothes on your back did not wear out and your feet did not swell these forty years. ⁵ Know then in your heart that as a parent disciplines a child so the Lord your God disciplines you. ⁶ Therefore keep the commandments of the Lord your God, by walking in his ways and by fearing him.
