Deuteronomy 4:1, 5, 9, 14

Then Moses said to the people, “Obey all the laws that I am teaching you, and you will live and occupy the land which the LORD, the God of your ancestors, is giving you.

“I have taught you all the laws, as the LORD my God told me to do. Obey them in the land that you are about to invade and occupy.

Be on your guard! Make certain that you do not forget, as long as you live, what you have seen with your own eyes. Tell your children and your grandchildren

The LORD told me to teach you all the laws that you are to obey in the land that you are about to invade and occupy.
