Revelation 12:7-10

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

8but he could not prevail, and there was no place for them in heaven any longer.

9So the great dragon was thrown out — the ancient serpent, who is called the devil and Satan, the one who deceives the whole world. He was thrown to earth, and his angels with him.

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