Deuteronomy 26:16-18

“This day the LORD your God commands you to observe these statutes and judgments; therefore you shall be careful to observe them with all your heart and with all your soul. Today 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. Also today the LORD has proclaimed you to be His special people, just as He promised you, that you should keep all His commandments
