Verse 14. - For they are the spirits of devils, working miracles. This explains the account given in ver. 13. In the plague of the frogs, the Egyptian magicians imitated the plague of Moses; the second beast (the false prophet) is represented as leading men astray by his miracles (Revelation 13:13). After the sixth trumpet came the digression, in which an account was given of the two witnesses of God, who worked miracles (Revelation 12.); here, after the sixth vial, we have a short digression, in which an account is given of the three witnesses of Satan, who endeavour rework on his behalf, by exhibiting miracles. (For the meaning of this working of miracles, see on Revelation 13:13.) Which go forth unto the kings of the earth and of the whole world; the kings of the whole world - omitting "of the earth" (Revised Version). The kings of the world are those whose aim and delight is the possession of the pleasures of this world; those who have their treasure in this world, and whose hearts are therefore also there; those who exercise their influence and power in regard only to the things of this world; in short, the worldly. To gather them to the battle of that great day of God Almighty; God, the Almighty. This battle is described in Revelation 19:11-21, which see. The great day is the last great judgment day. The battle referred to here, and described in Revelation 19, and again in Revelation 20:1-10, is apparently the battle which is being waged against God by the forces of evil all through the history of the world, from the fall of Adam until the last judgment day. This seems certain from the description given in Revelation 19. and 20. How, then, can it be described as the "battle of the great day"? Probably because on that day will occur the crisis, as it were, of the conflict; on that day will the issue be plainly determined, and the struggle terminated. Though the battle is proceeding daily, there is little to remind us of it; the very existence of, and necessity for, such warfare is sometimes forgotten in the daily round of life: at the last day will be plainly exhibited the nature of the incessant hostility between God and the devil, and the power of the latter will be manifested only to be visibly shattered and finally destroyed.

16:12-16 This probably shows the destruction of the Turkish power, and of idolatry, and that a way will be made for the return of the Jews. Or, take it for Rome, as mystical Babylon, the name of Babylon being put for Rome, which was meant, but was not then to be directly named. When Rome is destroyed, her river and merchandise must suffer with her. And perhaps a way will be opened for the eastern nations to come into the church of Christ. The great dragon will collect all his forces, to make one desperate struggle before all be lost. God warns of this great trial, to engage his people to prepare for it. These will be times of great temptation; therefore Christ, by his apostle, calls on his professed servants to expect his sudden coming, and to watch that they might not be put to shame, as apostates or hypocrites. However Christians differ, as to their views of the times and seasons of events yet to be brought to pass, on this one point all are agreed, Jesus Christ, the Lord of glory, will suddenly come again to judge the world. To those living near to Christ, it is an object of joyful hope and expectation, and delay is not desired by them.For they are the spirits of devils,.... They are of their father the devil; they are acted and influenced by him, he works effectually in them, and leads them captive at his will; they do his lusts, and are murderers and liars, and false teachers, like him:

working miracles; lying ones, to deceive men; this clearly points out who are meant, namely, the followers of antichrist, who, as they spread the doctrines of devils, endeavour to confirm them by signs and lying wonders:

which go forth unto the kings of the earth: those who have committed fornication with the Romish antichrist, such of them as will remain:

and of the whole world; as many Pagan princes as they can come at, and engage by any ways and means in their interest; they will go forth to them like the lying spirit to Ahab's prophets, 1 Kings 22:22

to gather them to the battle of that great day of God Almighty; that is, they will persuade them to gather together, to fight against the saints, the Gentile Christians in the several parts of the world, and the Jewish Christians, now settled in their own land; and this will be the battle of the Lord, who is God Almighty, and it will be fighting against him; and therefore the attempt must be vain and fruitless, and issue in the ruin of those who are gathered to it, who will be deceived and drawn into it by these diabolical spirits: and this is called "the battle of that great day of God"; not of the day of judgment, for it will be before that time; but of that day of vengeance upon all the remains of his and his church's enemies, both Pagan, Papal, and Mahometan, who will for this purpose be gathered together; "which", as the Ethiopic version renders it, "God has appointed".
