It's interesting that in Isaiah, Jerusalem is referred to as one of three sister cities that would seem to predate the wandering period of time under Moses.
This would beg the question of who or what Jerusalem originally belonged to. Considering that Ishmael was Egyptian and that many things from the Pharisee contain symbols from the Egyptian empire… It would be rather interesting if the Jews under Moses came to settle into a satellite city of Egypt. If Moses was the bastard son of the Pharaoh, that would also add some context to his upbringing and events surrounding exodus.
