Deuteronomy 8:3-4

And he humbled thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of the LORD doth man live.

Thy raiment waxed not old upon thee, neither did thy foot swell, these forty years.
