Deuteronomy 4: 1 - 2, 6 - 8
1 "And now, O Israel, give heed to the statutes and the ordinances which I teach you, and do them; that you may live, and go in and take possession of the land which the LORD, the God of your fathers, gives you.
2 You shall not add to the word which I command you, nor take from it; that you may keep the commandments of the LORD your God which I command you.
6 Keep them and do them; for that will be your wisdom and your understanding in the sight of the peoples, who, when they hear all these statutes, will say, `Surely this great nation is a wise and understanding people.'
7 For what great nation is there that has a god so near to it as the LORD our God is to us, whenever we call upon him?
8 And what great nation is there, that has statutes and ordinances so righteous as all this law which I set before you this day?
