Why does God bring all the armies of the world to the Middle East in the end times?
God brings the world's armies to the Middle East so He can trample them as grapes are trampled in a winepress. He will crush them with the final plague of hundred-pound hailstones, and the melting hail becomes a river of blood flowing as deep as horses' bridles.
Les explains that the analogy is the grape vat: just as vineyard keepers put their grapes into the vats and had somebody trample them, so God has brought all the armies of the world to the Middle East. He will trample them with the final plague of hailstones. Picture millions of troops in tents; a hundred-pound hailstone will do nothing but squash them like grapes in the vat. Revelation 14:20 says the winepress was trodden without the city, in the valleys north of Jerusalem. Blood comes out of the winepress even to the horse's bridles, a river of water and blood three to four feet deep, for 1,600 furlongs—about 180 miles, the distance from there down to the Red Sea. As the melting hail that crushed these millions melts in the Middle Eastern heat, it becomes a literal river of blood as deep as the horse's bridles.
