Deuteronomy 26:18-19

and Jehovah hath avouched thee this day to be a people for his own possession, as he hath promised thee, and that thou shouldest keep all his commandments; and to make thee high above all nations that he hath made, in praise, and in name, and in honor; and that thou mayest be a holy people unto Jehovah thy God, as he hath spoken.
