Hillel and Bnei Beteira

This is a lunch and learn I gave at Five Blocks. In it, I discuss why Bnei Beteira are not mentioned in the mishna, why they did not know the halacha that should have been a recurring event, why Hillel became the Nasi, and why his descendants were the leaders for the next several generations. I also give my theory about the first chapter of Pirkei Avot.
