8:10 {7} And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters;
(7) The third execution on the floods and fountains, that is, on all fresh water, in this verse: the effect of which is, that many are destroyed by the bitterness of the water, in the verse following.
8:10 THE THIRD TRUMPET.
And the third angel sounded. With the third trumpet the vision again changes.
And there fell a great star from heaven. Now a great, burning, blazing meteor falls upon a
third part of the rivers, and upon the fountains of the waters. A third part of the earth (Re 8:7); a third part of the sea (Re 8:8); and now a third part of the rivers are subjected to judgments.
8:10 And the third angel sounded, and there fell from heaven a great star, and it fell on the third part of the rivers - It seems Afric is meant by the rivers; (with which this burning part of the world abounds in an especial manner;) Egypt in particular, which the Nile overflows every year far and wide. ln the whole African history, between the irruption of the barbarous nations into the Roman empire, and the ruin of the western empire, after the death of Valentinian the Third, there is nothing more momentous than the Arian calamity, which sprung up in the year 315. It is not possible to tell how many persons, particularly at Alexandria, in all Egypt, and in the neighbouring countries, were destroyed by the rage of the Arians. Yet Afric fared better than other parts of the empire, with regard to the barbarous nations, till the governor of it, whose wife was a zealous Arian, and aunt to Genseric, king of the Vandals, was, under that pretence, unjustly accused before the empress Placidia. He was then prevailed upon to invite the Vandals into Afric; who under Genseric, in the year 428, founded there a kingdom of their own, which continued till the year 533. Under these Vandal kings the true believers endured all manner of afflictions and persecutions. And thus Arianism was the inlet to all heresies and calamities, and at length to Mahometanism itself. This great star was not an angel, (angels are not the agents in the two preceding or the following trumpet,) but a teacher of the church, one of the stars in the right hand of Christ. Such was Arius. He fell from on high, as it were from heaven, into the most pernicious doctrines, and made in his fall a gazing on all sides, being great, and now burning as a torch. He fell on the third part of the rivers - His doctrine spread far and wide, particularly in Egypt. And on the fountains of water - wherewith Afric abounds.
8:7-13 The first angel sounded the first trumpet, and there followed hail and fire mingled with blood. A storm of heresies, a mixture of dreadful errors falling on the church, or a tempest of destruction. The second angel sounded, and a great mountain, burning with fire, was cast into the sea; and the third part of the sea became blood. By this mountain some understand leaders of the persecutions; others, Rome sacked by the Goths and Vandals, with great slaughter and cruelty. The third angel sounded, and there fell a star from heaven. Some take this to be an eminent governor; others take it to be some person in power who corrupted the churches of Christ. The doctrines of the gospel, the springs of spiritual life, comfort, and vigour, to the souls of men, are corrupted and made bitter by the mixture of dangerous errors, so that the souls of men find ruin where they sought refreshment. The fourth angel sounded, and darkness fell upon the great lights of heaven, that give light to the world, the sun, and the moon, and the stars. The guides and governors are placed higher than the people, and are to dispense light, and kind influences to them. Where the gospel comes to a people, and has not proper effects on their hearts and lives, it is followed with dreadful judgments. God gives alarm by the written word, by ministers, by men's own consciences, and by the signs of the times; so that if people are surprised, it is their own fault. The anger of God makes all comforts bitter, and even life itself burdensome. But God, in this world, sets bounds to the most terrible judgments. Corruption of doctrine and worship in the church are great judgments, and also are the usual causes and tokens of other judgments coming on a people. Before the other three trumpets were sounded, there was solemn warning how terrible the calamities would be that should follow. If lesser judgments do not take effect the church and the world must expect greater; and when God comes to punish the world, the inhabitants shall tremble before him. Let sinners take warning to flee from the wrath to come; let believers learn to value and to be thankful for their privileges; and let them patiently continue in well doing.
