Deuteronomy 26:17-19

YLT(i) 17 Jehovah thou hast caused to promise to-day to become thy God, and to walk in His ways, and to keep His statutes, and His commands, and His judgments, and to hearken to His voice. 18 `And Jehovah hath caused thee to promise to-day to become His people, a peculiar treasure, as He hath spoken to thee, and to keep all His commands; 19 so as to make thee uppermost above all the nations whom He hath made for a praise, and for a name, and for beauty, and for thy being a holy people to Jehovah thy God, as He hath spoken.
