The word "Armageddon" is derived from the Hebrew words "Har", meaning "hill", and "Megiddo", or "Megiddon", meaning "place of crowds". Megiddo was an ancient city of Canaan which was assigned to the descendants of Manasseh. Manasseh was one of the two sons of Joseph by his Egyptian wife, Asenath. Joseph was the eleventh son of the Patriarch, Jacob. Megiddo is located on the southern rim of the plain of Esdraelon, six miles, or about ten kilometers, from Mount Carmel and eleven miles, or about eighteen kilometers, from Jesus' boyhood town of Nazareth. The Bible tells us that Har Megiddon, or Armageddon, played a very important role in ancient Israel, as we see by these verses:
"And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet. For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty. Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame. And he gathered them together into a place called in the Hebrew tongue Armageddon."
Revelation 16:13-16, KJV
