Revelation 16:14-16 Modern English Version (MEV)
14 For they are spirits of demons, performing signs, who go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
15 “Look, I am coming as a thief. Blessed is he who watches and keeps his garments on, lest he walk naked and his shame be exposed.”
16 They gathered them together to the place which in Hebrew is called Armageddon.
