Deuteronomy 4:2-4

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.
