Revelation 12:7

3 Then another sign appeared in heaven: a huge red dragon with seven heads, ten horns, and seven royal crowns on his heads.

4 His tail swept a third of the stars from the sky, tossing them to the earth. And the dragon stood before the woman who was about to give birth, ready to devour her child as soon as she gave birth.

5 And she gave birth to a son, a male child, who will rule all the nations with an iron scepter. And her child was caught up to God and to His throne.

6 And the woman fled into the wilderness, where God had prepared a place for her to be nourished for 1,260 days.

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

8 But the dragon was not strong enough, and no longer was any place found in heaven for him and his angels.

9 And the great dragon was hurled down—that ancient serpent called the devil and Satan, the deceiver of the whole world. He was hurled to the earth, and his angels with him.

10 And I heard a loud voice in heaven saying: “Now have come the salvation and the power and the kingdom of our God, and the authority of His Christ. For the accuser of our brothers has been thrown down—he who accuses them day and night before our God.

11 They have conquered him by the blood of the Lamb and by the word of their testimony. And they did not love their lives so as to shy away from death.
