Today you have proclaimed that the LORD is your God and that you will walk in His ways, keep His statutes and commandments and ordinances, and listen to His voice. / And today the LORD has proclaimed that you are His people and treasured possession as He promised, that you are to keep all His commandments, / that He will set you high in praise and name and honor above all the nations He has made, and that you will be a holy people to the LORD your God, as He has promised.
