Deuteronomy 26:16-19

The LORD your God commands you this day to follow these decrees and laws; carefully observe them with all your heart and with all your soul. You have declared this day that the LORD is your God and that you will walk in obedience to him, that you will keep his decrees, commands and laws—that you will listen to him. And the LORD has declared this day that you are his people, his treasured possession as he promised, and that you are to keep all his commands. He has declared that he will set you in praise, fame and honor high above all the nations he has made and that you will be a people holy to the LORD your God, as he promised.
