It shall come to pass, if thou shalt hearken diligently unto the voice of the Lord thy God, to observe and to do all His commandments which I command thee this day, that the Lord thy God will set thee on high above all nations of the earth: and all these blessings shall come on thee, and overtake thee, if thou shalt hearken unto the voice of the Lord thy God. Deut. 28:1, 2.
