Isnt the Battle of Jericho and Revelation similar...

Joshua's battle of Jericho accounted in the Book of Joshua and Christ battle of satan depicted in Revelation are more or likely same.

Its the reason why the Bible is so unique and theme is same even though it was written over and period of 1500 years.
