Deuteronomy 4:5-6

5“See, I have taught you statutes and judgments 1just as the Lord my God commanded me, that you are to do these things in the land where you are entering to take possession of it.

6So keep and do them, 2for that is your wisdom and your understanding in the sight of the peoples who will hear all these statutes and say, ‘Surely this great nation is a wise and understanding people.’
