Revelation 16:14-16 New Life Version (NLV)
14 These are demons that do powerful works. These demons go to all the kings of all the earth. They bring them together for the war of the great day of the All-powerful God.
15 (See! I will come like a robber. The man is happy who stays awake and keeps his clothes ready. He will not be walking around without clothes and be ashamed.) 16 Then the demons brought the kings together in the place called Armageddon in the Hebrew language.
