Deuteronomy 8:2-3

New American Standard Bible

^2 (A)And you shall remember all the way which the Lord your God has ^(B)led you in the wilderness these forty years, in order to humble you, ^(C)putting you to the test, to know what was in your heart, whether you would keep His commandments or not. ³ And He humbled you and let you go hungry, and fed you with the manna which you did not know, nor did your fathers know, in order to make you ^[a]understand that ^(D)man shall not live on bread alone, but man shall live on everything that comes out of the mouth of the Lord.
