2 And you shall remember the whole way that the Lord your God has led you pthese forty years in the wilderness, that he might humble you, qtesting you to know what was in your heart, whether you would keep his commandments or not. 3 And he humbled you and let you hunger and fed you with manna, which you did not know, nor did your fathers know, that he might make you know that rman does not live by bread alone, but man lives by every word1 that comes from the mouth of the Lord.
Deuteronomy 8:5
