This is the most valuable secular resource we have for life in First Century Palestine, written by a Jew who had access to materials now lost to history. Don't let the diffiiculties in reading Josephus put you off. The stories, the facts,the whole perspective is immensely fun to digest, and you will become accustomed to the language soon enough. Read for yourself all about the Jewish War and how the Romans eventually destroyed the city of Jerusalem. You will come away with a much deeper knowledge of what went on during the time the Gospels were being written, though of course Josephus does not mention them. Don't settle for secondary sources. This is the primary source for the period. You'll find unbelievable riches here.
Very informative and a great Bible study tool. Would recommend to all serious Bible scholars.
