Deuteronomy 26:17-19

17Today you have proclaimed the Lord to be your God, and that you will walk in His ways and keep His statutes, His commandments, and His judgments, and that you will obey His voice.

18Also today the Lord has proclaimed you to be His special people, just as He promised you, that you should keep all His commandments,

19and that He will set you high above all nations which He has made, in praise, in name, and in honor, and that you may be a holy people to the Lord your God, just as He has spoken.”
