Deuteronomy 4:1, 3

And now, O Israel, hearken unto the statutes and unto the ordinances, which I teach you, to do them; that ye may live, and go in and possess the land which Jehovah, the God of your fathers, giveth you.

Your eyes have seen what Jehovah did because of Baal-peor; for all the men that followed Baal-peor, Jehovah thy God hath destroyed them from the midst of thee.
