Who is Jehubabel from The Source; a Novel and what is their importance?

Jehubabel is the leader of the Jewish community in Makor in 167 B.C.E. when the flogging of the old man occurs. He is a descendant of Rimmon and his second wife Geula and their son Jehubabel. He is in the business of dyes and has his business right next to the synagogue. Jehubabel's son Menelaus, whose real name is Benjamin, is an athlete, an activity that his father has little use for. Jehobabel is committed to Judaism and keeps performing circumcisions. He and the Jews flee from Makor.
