Here let us consider the preface to this vision, and then the vision itself.

I.The preface to this vision: A voice was heard from the horns of the golden altar, Rev 9:13, Rev 9:14. Here observe, 1. The power of the church's enemies is restrained till God gives the word to have them turned loose. 2. When nations are ripe for punishment, those instruments of God's anger that were before restrained are let loose upon them, Rev 9:14. 3. The instruments that God makes use of to punish a people may sometimes lie at a great distance from them, so that no danger may be apprehended from them. These four messengers of divine judgment lay bound in the river Euphrates, a great way from the European nations. Here the Turkish power had its rise, which seems to be the story of this vision.

II.The vision itself: And the four angels that had been bound in the great river Euphrates were now loosed, Rev 9:15, Rev 9:16. And here observe, 1. The time of their military operations and executions is limited to an hour, and a day, and a month, and a year. Prophetic characters of time are hardly to be understood by us; but in general the time is fixed to an hour, when it shall begin and when it shall end; and how far the execution shall prevail, even to a third part of the inhabitants of the earth. God will make the wrath of man praise him, and the remainder of wrath he will restrain. 2. The army that was to execute this great commission is mustered, and the number found to be of horsemen two hundred thousand thousand; but we are left to guess what the infantry must be. In general, it tells us, the armies of the Mahomedan empire should be vastly great; and so it is certain they were. 3. Their formidable equipage and appearance, Rev 9:17. As the horses were fierce, like lions, and eager to rush into the battle, so those who sat upon them were clad in bright and costly armour, with all the ensigns of martial courage, zeal, and resolution. 4. The vast havoc and desolation that they made in the Roman empire, which had now become antichristian: A third part of them were killed; they went as far as their commission suffered them, and they could go no further. 5. Their artillery, by which they made such slaughter, described by fire, smoke, and brimstone, issuing out of the mouths of their horses, and the stings that were in their tails. It is Mr. Mede's opinion that this is a prediction of great guns, those instruments of cruelty which make such destruction: he observes, These were first used by the Turks at the siege of Constantinople, and, being new and strange, were very terrible, and did great execution. However, here seems to be an allusion to what is mentioned in the former vision, that, as antichrist had his forces of a spiritual nature, like scorpions poisoning the minds of men with error and idolatry, so the Turks, who were raised up to punish the antichristian apostasy, had their scorpions and their stings too, to hurt and kill the bodies of those who had been the murderers of so many souls. 6. Observe the impenitency of the antichristian generation under these dreadful judgments (Rev 9:20); the rest of the men who were not killed repented not, they still persisted in those sins for which God was so severely punishing them, which were, (1.) Their idolatry; they would not cast away their images, though they could do them no good, could not see, nor hear, nor walk. (2.) Their murders (Rev 9:21), which they had committed upon the saints and servants of Christ. Popery is a bloody religion, and seems resolved to continue such. (3.) Their sorceries; they have their charms, and magic arts, and rites in exorcism and other things. (4.) Their fornication; they allow both spiritual and carnal impurity, and promote it in themselves and others. (5.) Their thefts; they have by unjust means heaped together a vast deal of wealth, to the injury and impoverishing of families, cities, princes, and nations. These are the flagrant crimes of antichrist and his agents; and, though God has revealed his wrath from heaven against them, they are obstinate, hardened, and impenitent, and judicially so, for they must be destroyed.

III.From this sixth trumpet we learn, 1. God can make one enemy of the church to be a scourge and plague to another. 2. He who is the Lord of hosts has vast armies at his command, to serve his own purposes. 3. The most formidable powers have limits set them, which they cannot transgress. 4. When God's judgments are in the earth, he expects the inhabitants thereof should repent of sin, and learn righteousness. 5. Impenitency under divine judgments is an iniquity that will be the ruin of sinners; for where God judges he will overcome.

Breastplates of fire - jacinth, and brimstone - That is, red, blue, and yellow; the first is the color of fire, the second of jacinth, and the third of sulphur.

And the heads of the horses - Is this an allegorical description of great ordnance? Cannons, on the mouths of which horses' heads were formed, or the mouth of the cannon cast in that form? Fire, smoke, and brimstone, is a good allegorical representation of gunpowder. The Ottomans made great use of heavy artillery in their wars with the Greeks of the lower empire.

And thus I saw the horses in the vision, and them that sat on them,.... In such numbers, and with horsemen on them, and in such order, and in appearance, as follows:

having breastplates of fire, and of jacinth and brimstone; which may be understood either literally of their external breastplates, which being of polished iron, according to the custom of these people, looked at a distance like sparkling fire, and seemed to be of the colour of hyacinth, or of a sky colour, and appeared as flaming sulphur; though some think that their breastplates were of different colours, some looked like fire, others like jacinth, and others like brimstone; or it may denote that they would be accoutred in scarlet, blue, and yellow, which are the colours the Turks have commonly wore; or this may be understood of their internal breastplates, and the disposition of their minds, having in their breasts nothing but wrath, fury, desolation, and destruction; a fire devoured before them, and behind them a flame burned:

and the heads of the horses were as the heads of lions: gaping and roaring for their prey, or all bloody with it, and looked fierce, and savage, and terrible: this designs not so much the strength, boldness, and intrepidity of their horses, which are warlike creatures, and very undaunted in battle, as of the men that sat upon them, who were like David's heroes and warriors, Ch1 12:8.

And out of their mouths issued fire, and smoke, and brimstone; which may be referred either to the horses, or to the horsemen, or both: some interpret this allegorically, and by "fire" understand either the tyranny of the Turks over their own people, or their fury against others, or their blasphemy against God, and Christ, and his people, being like so many railing Rabshakehs against the God of the Christians; and by "smoke" the false doctrine of Mahomet, which came out of the same bottomless pit the doctrine of the Romish antichrist did; and is fitly compared to smoke for its disagreeableness, darkness, levity, and duration; See Gill on Rev 9:2; and by "brimstone" the immorality and sad corruption of manners among the Turks, and what is allowed of, or winked at, as fornication, polygamy, sodomy, &c. but rather this is to be taken more literally, and represents the firing of guns on horseback in battle. Guns are a late invention, and the use of them was found out in the age this trumpet refers to; and were much made use of by the Turks in their wars, and particularly great guns or cannons; these were used by Amurath at the sieges of Belgrade, and of Constantinople (m); and by Mahomet the Second at the taking of Constantinople, where a gun or cannon was used of that size, as to be drawn by seventy yoke of oxen, and two thousand men (n). Gunpowder set on fire is fitly signified by fire, smoke, and brimstone, which is made of nitre, charcoal, and brimstone; and the firing of guns on horseback is most aptly described by these coming out of the mouths of horses and horsemen: nor could it well appear to John to be otherwise, who could never have seen a gun, and one fired off in his life; nor could he well represent to others what he saw in vision, than in this manner.

thus--as follows.

of fire--the fiery color of the breastplates answering to the fire which issued out of their mouths.

of jacinth--literally, "of hyacinth color," the hyacinth of the ancients answering to our dark blue iris: thus, their dark, dull-colored breastplates correspond to the smoke out of their mouths.

brimstone--sulphur-colored: answering to the brimstone or sulphur out of their mouths.
