Deuteronomy 26:16-19
Because the Lord has declared Israel His treasured and holy people, Israel must walk in His ways and keep His commands with all heart and soul.
16 Today Yahweh your God commands you to do these statutes and ordinances. You shall therefore keep and do them with all your heart and with all your soul.
17 You have declared today that Yahweh is your God, and that you would walk in his ways, keep his statutes, his commandments, and his ordinances, and listen to his voice.
18 Yahweh has declared today that you are a people for his own possession, as he has promised you, and that you should keep all his commandments.
19 He will make you high above all nations that he has made, in praise, in name, and in honor; and that you may be a holy people to Yahweh your God, as he has spoken.
Because the LORD has declared Israel His treasured and holy people, Israel must walk in His ways and keep His commands with all heart and soul.
Moses formally gathers the detailed stipulations into a covenant declaration: the LORD commands Israel to keep His decrees and laws with whole-hearted obedience, Israel acknowledges the LORD as their God, and the LORD declares Israel to be His treasured, holy people as He promised.
Moses addresses Israel on the plains of Moab before they enter Canaan. The exodus generation has died, the new generation stands at the land threshold, and Deuteronomy renews the covenant by preaching the LORD's law, rehearsing His saving acts, and demanding faithful life in the land.
