Deuteronomy 4:1-6

“Now, O Israel, listen to the statutes and the judgments which I teach you to observe, that you may live, and go in and possess the land which the LORD God of your fathers is giving you. 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. Your eyes have seen what the LORD did at Baal Peor; for the LORD your God has destroyed from among you all the men who followed Baal of Peor. But you who held fast to the LORD your God are alive today, every one of you. “Surely I have taught you statutes and judgments, just as the LORD my God commanded me, that you should act according to them in the land which you go to possess. Therefore be careful to observe them; for this 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.’
