Deuteronomy 4:1, 3

Now therefore hearken, O Israel, unto the statutes and unto the judgments, which I teach you, for to do them, that ye may live, and go in and possess the land which the LORD God of your fathers giveth you.

Your eyes have seen what the LORD did because of Baal-peor: for all the men that followed Baal-peor, the LORD thy God hath destroyed them from among you.
