Book excerpt: What was the extent and nature of Jewish proselytizing activity amongst non-Jews in Palestine and the Greco-Roman diaspora leading up to and during the beginnings of the Christian era? Was there a clear missional direction? How did Second-Temple Judaism recruit converts and gain sympathizers? This book strives to address these questions, representing an update of the discussion while also breaking new ground. A "source book" of key texts is provided at the end.
