The destruction of Jerusalem and the Temple in AD 70 was a major event in the 1st Century for both Judaism and early Christianity. And even though that Jewish War and its massive destruction is not recorded in the New Testament, it was predicted by Jesus – most notably in Matthew chapter 24.
I recently had my good friend Tim Brinley recommend a 24 minute animated documentary about the Destruction of Jerusalem and the Temple. I had read several accounts of these events, but was still enlightened and impressed by this 24 minute video. It is conveniently available on YouTube and is produced by a small studio called Kings and Generals. This studio is primarily two history buffs with good technology and media skills who produce short animated videos about various important battles in world history. I highly recommend their documentary on the Siege of Jerusalem 70 AD!
