Deuteronomy 4:1, 5, 9, 14

“Now, Israel, listen to the rules and to the regulations that I am teaching you to do, in order that you may live and you may go in and you may take possession of the land that Yahweh, the God of your ancestors, is giving to you.

See, I now teach you rules and regulations just as Yahweh my God has commanded me, to observe them just so in the midst of the land where you are going, to take possession of it.

“However, take care for yourself and watch your inner self closely, so that you do not forget the things that your eyes have seen, so that they do not slip from your mind all the days of your life; and you shall make them known to your children and to your grandchildren.

And Yahweh charged me at that time to teach you rules and regulations for your observation of them in the land that you are about to cross into to take possession of it.
