In a free two-part series, Rabbi Garth Silberstein of Bais Abraham Congregation will examine the biblical narratives of the banishing of Ishmael and the binding of Isaac, to try and understand why these stories are associated with the Jewish New Year liturgy, and what they can teach us about the meaning of the holiday.
