Deuteronomy 4:1-6

“Now, O Israel, listen and pay attention to the statutes and the judgments (God’s legal decisions) which I am teaching you to do, so that you may live and go in and take possession of the land which the LORD, the God of your fathers, is giving you. You shall not add to the word which I am commanding you, nor take away from it, so that you may keep the commandments of the LORD your God which I am commanding you. Your eyes have seen what the LORD did at Baal-peor; for all the men who followed [and participated in the worship of] Baal of Peor, the LORD your God destroyed them from among you, [Num 25:1-9] but you who held tightly to the LORD your God are alive today, every one of you. “Look, I have taught you statutes and judgments just as the LORD my God has commanded me, so that you may do them in the land which you are entering to possess. So keep and do them, for 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.’
