14 for they are spirits of demons, working signs; which go forth [a]unto the kings of the whole [b]world, to gather them together unto the war of the great day of God, the Almighty. 15 (Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.) 16 And they gathered them together into the place which is called in Hebrew [c]Har-Magedon.
