Revelation 16:14-16

These evil spirits are the spirits of demons, which have power to do miracles. They go out to the kings of the whole world to gather them together for the battle on the great day of God Almighty. “Listen! I will come as a thief comes! Blessed are those who stay awake and keep their clothes on so that they will not walk around naked and have people see their shame.” Then the evil spirits gathered the kings together to the place that is called Armageddon in the Hebrew language.
