Deuteronomy 26:16-18

“This day the LORD your God commands you to do these statutes and rules. You shall therefore be careful to do them with all your heart and with all your soul. You have declared today that the LORD is your God, and that you will walk in his ways, and keep his statutes and his commandments and his rules, and will obey his voice. And the LORD has declared today that you are a people for his treasured possession, as he has promised you, and that you are to keep all his commandments
