Armageddon is an Anglicized version of the Hebrew har-Megiddo. Har means hill rather than something to laugh at, and nobody will be amused at this very sad and terrifying time for humanity. Kings of the earth and their armies will “gather” in a valley called Megiddo for “the battle of that great day of God Almighty" (Revelation 16:13-16 Revelation 16:13-16  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 to 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 watches, and keeps 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.
American King James Version×). Historically lots of battles have been fought here. But not this time.
Precisely put, they gather here, but the battle will take place elsewhere. Where?
Megiddo is about 80 miles north of Jerusalem. The kings and their armies will mobilize down to the Kidron Valley that runs north and south between the Mount of Olives and the eastern gate of Jerusalem. This makes perfect logistical sense, since at His return, Jesus is going to stand on the Mount of Olives (Zechariah 14:4 Zechariah 14:4And his feet shall stand in that day on the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall split in the middle thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
American King James Version×). And it stands to reason that He will majestically make a triumphant royal processional walk into Jerusalem—through the Lion of Judah eastern gate—that is walled up and reserved for His arrival.
My feet have stood on the Mount of Olives and walked down to the wall, which is close enough to hardly break a sweat. Of course, if Jesus chooses to just pop on over, who will stop Him?
Not the armies, which are merely like grapes clustered in the valley and destined to be stomped in the winepress of His wrath. How do they think they will even have a chance fighting the Son of God, except through strong delusion by the one who relentlessly keeps up his losing cause?
Joel 3:11-16 Joel 3:11-16  Assemble yourselves, and come, all you heathen, and gather yourselves together round about: thither cause your mighty ones to come down, O LORD.
 Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about.
 Put you in the sickle, for the harvest is ripe: come, get you down; for the press is full, the fats overflow; for their wickedness is great.
 Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision.
 The sun and the moon shall be darkened, and the stars shall withdraw their shining.
 The LORD also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the LORD will be the hope of his people, and the strength of the children of Israel.
American King James Version×and Zechariah 14:12-15 Zechariah 14:12-15  And this shall be the plague with which the LORD will smite all the people that have fought against Jerusalem; Their flesh shall consume away while they stand on their feet, and their eyes shall consume away in their holes, and their tongue shall consume away in their mouth.  And it shall come to pass in that day, that a great tumult from the LORD shall be among them; and they shall lay hold every one on the hand of his neighbor, and his hand shall rise up against the hand of his neighbor.  And Judah also shall fight at Jerusalem; and the wealth of all the heathen round about shall be gathered together, gold, and silver, and apparel, in great abundance.  And so shall be the plague of the horse, of the mule, of the camel, and of the ass, and of all the beasts that shall be in these tents, as this plague.
American King James Version×warn about this earth-shaking battle. Joel says the Kidron Valley is also called the Valley of Jehoshaphat and refers to it as “the valley of decision.” Anybody who gathers in Megiddo or shows up for the Battle of Jehoshaphat in the Kidron Valley has already made the wrong decision!
For anybody fighting against Christ and His heavenly armies, it will seem like the end of the world! But actually Jesus will come to the rescue just before there would be no flesh saved alive (Matthew 24:22 Matthew 24:22And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
American King James Version×), and restore the earth to 1,000 years of joy, peace and prosperity.
So "the Battle of Armageddon?" "The end of the world?" The battle will be in a different place and in truth, it will be the beginning for the world.
