Revelation 12:3–9
3 And another portent appeared in heaven; behold, a great red dragon, with seven heads and ten horns, and seven diadems upon his heads. 4 His tail swept down a third of the stars of heaven, and cast them to the earth. And the dragon stood before the woman who was about to bear a child, that he might devour her child when she brought it forth; 5 she brought forth a male child, one who is to rule all the nations with a rod of iron, but her child was caught up to God and to his throne, 6 and the woman fled into the wilderness, where she has a place prepared by God, in which to be nourished for one thousand two hundred and sixty days.
7 Now war arose in heaven, Michael and his angels fighting against the dragon; and the dragon and his angels fought, 8 but they were defeated and there was no longer any place for them in heaven. 9 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.
