Revelation 12:9-10

9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.

Revelation 12:9-10 Meaning and Commentary

INTRODUCTION TO REVALATION 12

This chapter contains a vision of two wonders or signs seen in heaven, a woman and a dragon, and an account of what followed thereon, war both in heaven and earth. The vision of the woman is in Re 12:1,2, who is described by her being clothed with the sun; by her having the moon under her feet; by a crown of twelve stars on her head; and by her pregnancy, travail, pains, and cry. The vision of the dragon is in Re 12:3,4, who is described by his size, a great one; by his colour, red; by the number of his heads and horns, and the crowns on the former; by the force and strength of his tail, drawing and casting: down to the earth the third part of the stars of heaven; and by his position, standing before the woman, in order to devour her child when born. Next follows an account of the birth of her child, and what became of that and her: the child is said to be a man child, is described as a monarch, and as advanced to great honour and dignity; but she flies into the wilderness, where a place is prepared for her of God, and where she is hid for the space of 1260 days, Re 12:5,6; upon this ensues a war in heaven; the combatants on one side were Michael and his angels, and on the other the dragon and his; the issue of which was, that the latter were conquered, and cast out into the earth, Re 12:7-9, on account of which victory a triumphant song is sung by the inhabitants of heaven, because of salvation and strength that were come to them; and because of the kingdom and power of Christ, which now took place; and because of the ejection of Satan, the accuser of their brethren; in which song also notice is taken of the manner in which Satan was overcome by those he accused, by the blood of the Lamb, by the word of their testimony, and by their death; and it is concluded with an apostrophe to those that dwell in heaven, calling on them to rejoice, and to the inhabitants of the earth denouncing woe to them, because the devil was among them, whose wrath was great, his time being short, Re 12:10-12. Next follow the dragon's persecution of the woman, and her flight into the wilderness, and the care took of her there, as before described, Re 12:13,14; then the method the serpent took to annoy her, the help she received from the earth, and the wrath of the dragon upon that; which put him upon making war with the remnant of her seed, who kept the commandments of God, and had the testimony of Jesus, Re 12:15-17.

Revelation 12:9-10 In-Context

7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
8 And prevailed not; neither was their place found any more in heaven.
9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
11 And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.
12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
