First, is it true that nowadays, anyone with the last names Cohen or Levi are descended from one of the twelve groups of High Priests of Ancient Egypt? Learned so in my Humanities class but just want to confirm before I say it and sound stupid.
Also please feel free to throw down any fun facts that I could put into the speech.
Cohen means priest in hebrew, so why are you mentionning ancient Egypt? Assuming you made a confusion between the Hebrews and the Egyptians, you are partly right. Priesthood, and by that I means all priesthood and not just the main one were supposed to be occupied by the descendant of Aaron the brother of Moses. This of course is part of a (semi?) mythical ancestry in a tale that had been rewritten over the centuries of evolution that gave birth to Judaism. May I ask you the subject of your speech, as a confusion between the hebrews and the egyptians is not a minor one?
