Revelation 12:3-12 American Standard Version (ASV)
3 And there was seen another sign in heaven: and behold, a great red dragon, having seven heads and ten horns, and upon his heads seven diadems. 4 And his tail draweth the third part of the stars of heaven, and did cast them to the earth: and the dragon standeth before the woman that is about to be delivered, that when she is delivered he may devour her child. 5 And she was delivered of a son, a man child, who is to rule all the [a]nations with a rod of iron: and her child was caught up unto God, and unto his throne. 6 And the woman fled into the wilderness, where she hath a place prepared of God, that there they may nourish her a thousand two hundred and threescore days.
7 And there was war in heaven: Michael and his angels going forth to war with the dragon; and the dragon warred and his angels; 8 and they prevailed not, neither was their place found any more in heaven. 9 And the great dragon was cast down, the old serpent, he that is called the Devil and Satan, the deceiver of the whole [b]world; he was cast down to the earth, and his angels were cast down with him. 10 And I heard a great voice in heaven, saying,
[c]Now is come the salvation, and the power, and the kingdom of our God, and the authority of his Christ: for the accuser of our brethren is cast down, who accuseth them before our God day and night. 11 And they overcame him because of the blood of the Lamb, and because of the word of their testimony; and they loved not their life even unto death. 12 Therefore rejoice, O heavens, and ye that [d]dwell in them. Woe for the earth and for the sea: because the devil is gone down unto you, having great wrath, knowing that he hath but a short time.
