Revelation 16:14-16 Evangelical Heritage Version (EHV)
14 They are, in fact, miracle-working, demonic spirits, which go out to the kings of the whole earth[a] to bring them together for the battle on the great day of the Almighty God.
15 “Look: I am coming like a thief. Blessed is the one who stays awake and keeps his clothes on, so that he does not walk around naked and his shame is not seen.”
16 Then they brought them together to the place that in Hebrew is called Armageddon.
