Deuteronomy 4:1, 5, 9, 14

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.

Behold, I have taught you statutes and ordinances, even as Jehovah my God commanded me, that ye should do so in the midst of the land whither ye go in to possess it.

Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes saw, and lest they depart from thy heart all the days of thy life; but make them known unto thy children and thy children’s children

And Jehovah commanded me at that time to teach you statutes and ordinances, that ye might do them in the land whither ye go over to possess it.
