Deuteronomy 4:5-6

KJ2000(i) 5 Behold, I have taught you statutes and judgments, even as the LORD my God commanded me, that you should do so in the land where you go to possess it. 6 Keep therefore and do them; for this is your wisdom and your understanding in the sight of the nations, which shall hear all these statutes, and say, Surely this great nation is a wise and understanding people.
