Walk like an Egyptian
Moses spent his childhood and adolescent years living in Pharaoh's house as an adopted son. If you know what's in store for him, you see some obvious pluses, such as: later, when God tells Moses "go to Pharoah and say..." Moses will actually know how to go to Pharaoh. I mean, it might seem silly, but doesn't knowing what door to enter, what floor Pharaoh's throne room is on, how many steps to the podium, which person can notify the man in charge that you've arrived, where to park your camel - doesn't knowing all of those practical things remove a whole layer of fear regarding "go to Pharaoh and say"?
