And prevailed not - Satan and his angels failed in their purpose.

Neither was their place found any more in heaven - They were cast out, and were seen there no more. The idea is, that they were defeated and driven away, though for a time they were suffered to carry on the warfare elsewhere.

And prevailed not - Against the cause of Christianity.

Neither was their place found any more in heaven - The advocates of the heathen idolatry were prevented from having any farther share in the government of the empire. The wonderful success of Constantine over all his enemies, and his final triumph over Licinius, correspond exactly to the symbolical language in this verse.

And prevailed not,.... That is, the dragon, or the devil, and his angels, prevailed not against Michael and his angels; but, on the other hand, were conquered by them, as the above tyrants were by Constantine and Theodosius: some copies read in the singular number, "and he prevailed not", as the Alexandrian copy, the Complutensian edition the Arabic and Ethiopic versions; and other copies in the plural number, "they prevailed not": and as the Vulgate Latin and Syriac versions:

neither was their place found any more in heaven; in the Roman empire; or "his place", as some copies and versions: this was the time of the judgment of the world, or of the empire as Pagan; Satan the prince of the world, who had long governed in it, was now cast out of all power and authority in it, and all the idol gods in whom he was worshipped, with all the idolatrous priests; nor were there any more any Heathen emperors, for after Constantine's time there was only Julian the apostate, and who reigned but a little while; and after Theodosius, who cleared the empire of Paganism, there never was any, and there is reason to believe there never will be.

Prevailed (ἴσχυσαν)

See on Luke 14:30; see on Luke 16:3; see on James 5:16.

{15} And prevailed not; neither was their {a} place found any more in heaven.

(15) The description of the victory, by the denying of the thing in this verse, and by affirming the opposite in Re 12:9. As Satan gained nothing in heaven, but was by the power of God thrown down into the world of which he is the prince, Christ himself and his elect members standing still by the throne of God.

(a) They were cast out so, that they were never seen any more in heaven.

12:7,8 And there was war in heaven. The woman had been seen in heaven, and there she is seen to be assailed. She has, however, a champion who fights her battles.

12:8 And he prevailed not - The dragon himself is principally mentioned; but his angels, likewise, are to be understood. Neither was this place found any more in heaven - So till now he had a place in heaven. How deep a mystery is this! One may compare this with Luke 10:18; Eph 2:2; 4:8; 6:12.

8. prevailed not-A and Coptic read, "He prevailed not." But B and C read as English Version.

neither-A, B, and C read, "not even" (Greek, "oude"): a climax. Not only did they not prevail, but not even their place was found any more in heaven. There are four gradations in the ever deeper downfall of Satan: (1) He is deprived of his heavenly excellency, though having still access to heaven as man's accuser, up to Christ's first coming. As heaven was not fully yet opened to man (Joh 3:13), so it was not yet shut against Satan and his demons. The Old Testament dispensation could not overcome him. (2) From Christ, down to the millennium, he is judicially cast out of heaven as the accuser of the elect, and shortly before the millennium loses his power against Israel, and has sentence of expulsion fully executed on him and his by Michael. His rage on earth is consequently the greater, his power being concentrated on it, especially towards the end, when "he knoweth that he hath but a short time" (Re 12:12). (3) He is bound during the millennium (Re 20:1-3). (4) After having been loosed for a while, he is cast for ever into the lake of fire.

12:7-11 The attempts of the dragon proved unsuccessful against the church, and fatal to his own interests. The seat of this war was in heaven; in the church of Christ, the kingdom of heaven on earth. The parties were Christ, the great Angel of the covenant, and his faithful followers; and Satan and his instruments. The strength of the church is in having the Lord Jesus for the Captain of their salvation. Pagan idolatry, which was the worship of devils, was cast out of the empire by the spreading of Christianity. The salvation and strength of the church, are only to be ascribed to the King and Head of the church. The conquered enemy hates the presence of God, yet he is willing to appear there, to accuse the people of God. Let us take heed that we give him no cause to accuse us; and that, when we have sinned, we go before the Lord, condemn ourselves, and commit our cause to Christ as our Advocate. The servants of God overcame Satan by the blood of the Lamb, as the cause. By the word of their testimony: the powerful preaching of the gospel is mighty, through God, to pull down strong holds. By their courage and patience in sufferings: they loved not their lives so well but they could lay them down in Christ's cause. These were the warriors and the weapons by which Christianity overthrew the power of pagan idolatry; and if Christians had continued to fight with these weapons, and such as these, their victories would have been more numerous and glorious, and the effects more lasting. The redeemed overcame by a simple reliance on the blood of Christ, as the only ground of their hopes. In this we must be like them. We must not blend any thing else with this.
