Deuteronomy 8:2-4

Darby Translation

² And thou shalt remember all the way which Jehovah thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thy heart, whether thou wouldest keep his commandments or not.

³ And he humbled thee, and suffered thee to hunger, and fed thee with the manna, which thou hadst not known, and which thy fathers knew not; that he might make thee know that man doth not live by bread alone, but by everything that goeth out of the mouth of Jehovah doth man live.

⁴ Thy clothing grew not old upon thee, neither did thy foot swell, these forty years.
