Revelation 12:7-17King James Version (KJV) 7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
How do angels fight?
All Christian, Jewish and Islamic authors accepted. Canonical, mystical etc.
Here are some cases of binding I know of:
Revelation 20New International Version (NIV) The Thousand Years 20 And I saw an angel coming down out of heaven, having the key to the Abyss and holding in his hand a great chain. 2 He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years. 3
And in Tobit
3 The reek of the fish distressed the demon, who fled through the air to Egypt. Raphael pursued him there, shackled him and strangled him forthwith.
Binding and shackling does seem to be the main way for an angel to deal with an enemy, but are there others? Has an angel ever used a sword for anything but guarding the way to the Tree of Life?
