Deuteronomy 4:5-6

Darby(i) 5 See, I have taught you statutes and ordinances, even as Jehovah my God commanded me, that ye may do so in the land into which ye enter to possess it. 6 And ye shall keep and do them; for that will be your wisdom and your understanding before the eyes of the peoples that shall hear all these statutes, and say, Verily this great nation is a wise and understanding people.
