Deuteronomy Chapter 8

8:3-5
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.
Thou shalt also consider in thine heart, that, as a man chasteneth his son, so the Lord thy God chasteneth thee.

8:7-9
For the Lord thy God bringeth thee into a good land, a land of brooks of water, of fountains and depths that spring out of valleys and hills;
A land of wheat, and barley, and vines, and fig trees, and pomegranates; a land of oil olive, and honey;
A land wherein thou shalt eat bread without scarceness, thou shalt not lack any thing in it; a land whose stones are iron, and out of whose hills thou mayest dig brass.

8:15
Who led thee through that great and terrible wilderness, wherein were fiery serpents, and scorpions, and drought, where there was no water; who brought thee forth water out of the rock of flint.
