Remember the Lord Your God (Deuteronomy 8)

      and go in and possess the land of which the Lord swore to your fathers.  And you shall remember that the Lord your God led you all the way these forty years in the wilderness, to humble you and test you, to know what was in your heart, whether you would keep His commandments or not.  So He humbled you, allowed you to hunger, and fed you with manna which you did not know nor did your fathers know, that man shall not  live by bread alone; but man lives by every word that proceeds from the mouth of the Lord.
