The Book of Revelation KJV 1611,,,,Is How God Says It Will End
John, the Greek Judean who wrote Revelation chose Megiddo for his mythical final battle because of it's location on the international road between Judea and the Northern Kingdom. (and between Egypt and Assyria) Over the centuries this is the way invading armies came, so it was a place his readers would recognize and would associate with calamity.
Here is a really good look at the digs that have gone on in the city. It was occupied from early bronze up until the Chicago dig in the first half of the 20th century. Really the only site like it that can be gotten to. (and has a special place in my heart because Pharos Tutmose III conquered the town, then wrote about it)
The gospels, especially the synoptics, are examples of some of the best classic Greek literature. You really should read a better translation than KJV.
