Revelation 16:14-16
16:14 For they are the spirits of the demons performing signs who go out to the kings of the earth
to bring them together for the battle that will take place on the great day of God, the All-Powerful.
16:15 (Look! I will come like a thief!
Blessed is the one who stays alert and does not lose his clothes so that he will not have to walk around naked and his shameful condition be seen.)
16:16 Now the spirits gathered the kings and their armies to the place that is called Armageddon in Hebrew.
