Moses looks on the history of the birth of the People of Israel  the music here is the same as Moses the Law Giver. I am just trying to figure out how to put this kind of thing together. There is Michelangelo's Leah and Rachel and various events. There is the expulsion from Gan Eden. The giving of the Torah is a way to bring us back into the Garden of Eden but we have to go through the fiery swords of the angels guarding the way .
