The forces of Ananus besieged the Zealots who held the Temple. When John of Giscala led the Zealots to believe that Ananus had contacted the Roman General Vespasian for assistance in retaking control of all Jerusalem, the Zealots, driven to desperation, asked the Edomites (Idumeans) for assistance in preventing the delivery of the city to the Romans. When the Edomites arrived, the Zealots opened the gates of Jerusalem to them, and the Edomites slaughtered ben Hanan's (Ananus ben Ananus) forces, killing him as well.
