Revelation 12:7-11

Then there was a war in heaven. Michael and his angels fought against the dragon, and the dragon and his angels fought back. But the dragon was not strong enough, and he and his angels lost their place in heaven. The giant dragon was thrown down out of heaven. (He is that old snake called the devil or Satan, who tricks the whole world.) The dragon with his angels was thrown down to the earth. Then I heard a loud voice in heaven saying: “The salvation and the power and the kingdom of our God and the authority of his Christ have now come. The accuser of our brothers and sisters, who accused them day and night before our God, has been thrown down. And our brothers and sisters defeated him by the blood of the Lamb’s death and by the message they preached. They did not love their lives so much that they were afraid of death.
