Revelation 12:7 | The War in Heaven
6, 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 — the 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.
12, Therefore rejoice, O heavens, and you who dwell in them! But woe to the earth and the sea; with great fury the devil has come down to you, knowing he has only a short time.”
13, And when the dragon saw that he had been thrown to the earth, he pursued the woman who had given birth to the male child.
14, But the woman was given two wings of a great eagle to fly from the presence of the serpent to her place in the wilderness, where she was nourished for a time, and times, and half a time.
15, Then from the mouth of the serpent spewed water like a river to overtake the woman and sweep her away in the torrent.
16, But the earth helped the woman and opened its mouth to swallow up the river that had poured from the dragon’s mouth.
17, And the dragon was enraged at the woman, and went to make war with the rest of her children, who keep the commandments of God and hold to the testimony of Jesus. And the dragon stood on the sand of the seashore.
