Revelation 12:7-10

7Then war broke out in heaven: Michael and his angels fought against the dragon, and the dragon and his angels fought back.

8But the dragon was not strong enough to prevail, so there was no longer any place left in heaven for him and his angels.

9So that huge dragon – the ancient serpent, the one called the devil and Satan, who deceives the whole world – was thrown down to the earth, and his angels along with him.

10Then I heard a loud voice in heaven saying, “The salvation and the power and the kingdom of our God, and the ruling authority of his Christ, have now come, because the accuser of our brothers and sisters, the one who accuses them day and night before our God, has been thrown down.
