Deuteronomy 4:9-10

9Again, however, pay very careful attention, lest you forget the things you have seen and disregard them for the rest of your life; instead teach them to your children and grandchildren.

10You stood before the Lord your God at Horeb and he said to me, “Assemble the people before me so that I can tell them my commands. Then they will learn to revere me all the days they live in the land, and they will instruct their children.”
