Deuteronomy 26:18-19

18Today the Lord has declared that you are His people, His treasured possession, just as He promised you, and that you are to keep all His commandments;

19and that He will set you high above all the nations which He has made, for praise, fame, and honor: and that you shall be a holy people [set apart and consecrated] to the Lord your God, just as He has spoken.”
