Rev 12:7-9

Michael Defeats the Dragon 7And war broke out in heaven; Michael and his angels fought against the dragon. The dragon and his angels fought back,8but they were defeated, and there was no longer any place for them in heaven.9The 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.
