Revelation 16:14-17

14Those bad spirits are the spirits of demons. They had the power to do miracles. They went to all the rulers in the whole world, to bring them together to fight in a big war. That war will happen on the great day of God, who has all power and authority.

15The Lord says: ‘Listen! I will come secretly, like someone who robs people. If you continue to watch carefully, you will be happy. Keep your clothes with you all the time. Then, when I come, you will not be ashamed because you have no clothes.’

16Then the bad spirits brought the rulers together to fight in the big war. They came to the place that is called Armageddon in the Hebrew language.

17Then the seventh angel poured out his bowl into the air. A voice spoke loudly from the throne in God's house. The voice said, ‘Now it has happened!’
