deut 26:17-19
Today you are making this agreement with the LORD: he is to be your God and you are to walk in his ways and observe his statutes, commandments and decrees, and to hearken to his voice. And today the LORD is making this agreement with you: you are to be a people peculiarly his own, as he promised you; and provided you keep all his commandments, he will then raise you high in praise and renown and glory above all other nations he has made, and you will be a people sacred to the LORD, your God, as he promised.".
