“Now these are the commandments, the statutes, and the judgments, which the Lord your God commanded to teach you, that ye might do them in the land whither ye go to possess it:”
Now this is the commandment, the statutes, and the ordinances, which the LORD your God commanded me to teach you, that you may do them in the land whither you go to possess it; -- the preamble frames the law as commandment (mitzvah) and introduces the Shema section. The law is for application in Canaan; obedience is territorial as well as covenantal.
