Deuteronomy 4:5-6

JPS_ASV_Byz(i) 5 Behold, I have taught you statutes and ordinances, even as the LORD my God commanded me, that ye should do so in the midst of the land whither ye go in to possess it. 6 Observe therefore and do them; for this is your wisdom and your understanding in the sight of the peoples, that, when they hear all these statutes, shall say: 'Surely this great nation is a wise and understanding people.'
