Also, The apocryphal Book of Enoch recounts that a group of rebellious angels left heaven and came down to Earth to marry human women and have children with them. This goes along with the accounts of the Nephilim in the days of Noah.
Actually, it merely calls them the "Sons of God". "They found the Daughters of Man beautiful and came down and had children by them. These were the heroes of Old, the giants and warriors of the world." So we can imply that they are angels or some sort of divine beings, but doesnt make them "rebellious".
Now war arose in heaven, Michael and his angels fighting against the dragon. And the dragon and his angels fought back, but he was defeated, and there was no longer any place for them in heaven. And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world—he was thrown down to the earth, and his angels were thrown down with him. Revelation 12:7-9.
.....Honestly, Hawthorn old chap, you're going to throw, of all books, Revelation at me? :/ Dude, honestly?
There's exactly seven different accounts of Revelation. 7 different books, all prophesying different stuff about the end. Furthermore, the Bible as a whole has been translated, altered, and switched around dozens of times. Things have been added, subtracted, and completely changed in meaning. Revelation is the PRIMARY offender of this. Honest to God, trust me when I say this, cross my heart and hope to die, earliest possible non-bastardized version of Revelation doesnt even mention or his angels. :/ It mentions the Dragon and the Beast, yeah! But it doesnt outright claim anything of Satan and his multi-tude of fallen. I think that bit came around when it got translated into German. Originally, it was just something against the Romans. Back then, when they said Christ would return and establish the Kingdom, they were thinking in like, 10 or 20 years or so. They thought the end was coming soon, not like... millenia later!
