“Only be watchful and watch over your soul closely, so you do not forget the things your eyes have seen and they slip from your heart all the days of your life. You are to make them known to your children and your children’s children.
You are to remember all the way that Adonai your God has led you these 40 years in the wilderness—in order to humble you, to test you, to know what was in your heart, whether you would keep His mitzvot or not.
