Deuteronomy 4:3

Now, Israel, listen to the statutes and to the ordinances which I teach you, to do them, that you may live and go in and possess the land which the LORD, the God of your fathers, gives you.

You shall not add to the word which I command you, neither shall you take away from it, that you may keep the commandments of the LORD your God which I command you.

But you who were faithful to the LORD your God are all alive today.

Behold, I have taught you statutes and ordinances, even as the LORD my God commanded me, that you should do so in the middle of the land where you go in to possess it.

Keep therefore and do them; for this is your wisdom and your understanding in the sight of the peoples who shall hear all these statutes and say, “Surely this great nation is a wise and understanding people.”
