Flavius Josephus, a Jewish priest and Pharisee, was put in command of the national resistance in Galilee at the time of Israel's revolt against Rome. When he was captured at Jotapata; his life was spared upon his prediction to Vespasian that the Roman general would soon become emperor. Upon the fulfillment of this prophecy, he was commissioned to provide his captors with a history of the Jewish people, although he initially wrote a history of the Roman-Jewish war suited for both a Roman and a Jewish audience. His works, disputed though they may be, are an indispensable source on the life and history of Roman Judea.
Joesphus records the destruction of Jerusalem in AD 70 by the Romans. It is this period that serves as the back drop of the Book of Revelation. This material has been made availabe by http://preteristarchive.com/ to whom we are gradeful.
