Deuteronomy 4:9-10

But be careful! Watch out and don’t forget the things you have seen. Don’t forget them as long as you live, but teach them to your children and grandchildren. Remember the day you stood before the LORD your God at Mount Sinai. He said to me, “Bring the people together so I can tell them what I have to say. Then they will respect me as long as they live in the land, and they will teach these things to their children.”
