Deuteronomy 8:2-3

MSTC(i) 2 And think on all the ways which the LORD thy God led thee this forty years in the wilderness, for to humble thee and to prove thee, to wete what was in thine heart, whether thou wouldest keep his commandments or no. 3 He humbled thee and made thee hunger and fed thee with Manna, which neither thou nor thy father knew of, to make thee know that a man must not live by bread only: but by all that proceedeth out of the mouth of the LORD must a man live.
