New Defender's Study Bible Notes
12:7 dragon. At this time of Jacob’s trouble, the archangel Michael will “stand up” for them (Daniel 12:1), and this will result in a great war in heaven—probably in the atmospheric heaven, which had been Satan’s domain, and where the Lord has met with His redeemed and raptured saints. There Satan and his angels then will be defeated and cast permanently down to the earth (Revelation 12:9). How this war will be fought has not been revealed, but both faithful and fallen angels have tremendous energies and powers, of which humans have little comprehension.
