91 And at the sounding of the fifth angel I saw a star falling from heaven to the earth: and there was given to him the key of the great deep. 2 And he made the great deep open and a smoke went up from it, like the smoke of a great oven; and the sun and the air were made dark because of the smoke. 3 And from the smoke locusts came out on the earth; and power was given them, like the power of scorpions. 4 And they were ordered to do no damage to the grass of the earth, or any green thing, or any tree, but only to such men as have not the mark of God on their brows. 5 And orders were given them not to put them to death, but to give them great pain for five months: and their pain was as the pain from the wound of a scorpion. 6 And in those days men will be hoping for death, and it will not come to them; and they will have a great desire for death, and death will go in flight from them. 7 And the forms of the locusts were like horses made ready for war; and on their heads they had crowns like gold, and their faces were as the faces of men. 8 And they had hair like the hair of women, and their teeth were as the teeth of lions. 9 And they had breastplates like iron, and the sound of their wings was as the sound of carriages, like an army of horses rushing to the fight. 10 And they have pointed tails like scorpions; and in their tails is their power to give men wounds for five months. 11 They have over them as king the angel of the great deep: his name in Hebrew is Abaddon, and in the Greek language Apollyon. 12 The first Trouble is past: see, there are still two Troubles to come.
13 And at the sounding of the sixth angel a voice came to my ears from the horns of the gold altar which is before God, 14 Saying to the sixth angel who had the horn, Make free the four angels who are chained at the great river Euphrates. 15 And the four angels were made free, who were ready for the hour and day and month and year, that they might put to death a third part of men. 16 And the number of the armies of the horsemen was twice ten thousand times ten thousand: the number of them came to my ears. 17 And so I saw the horses in the vision, and those who were seated on them, having breastplates of fire and glass and of burning stone: and the heads of the horses were as the heads of lions; and out of their mouths came fire and smoke and a smell of burning.

Commentary on Revelation 9:1-12
(Read Revelation 9:1-12)
Upon sounding the fifth trumpet, a star fell from heaven to the earth. Having ceased to be a minister of Christ, he who is represented by this star becomes the minister of the devil; and lets loose the powers of hell against the churches of Christ. On the opening of the bottomless pit, there arose a great smoke. The devil carries on his designs by blinding the eyes of men, by putting out light and knowledge, and promoting ignorance and error. Out of this smoke there came a swarm of locusts, emblems of the devil's agents, who promote superstition, idolatry, error, and cruelty. The trees and the grass, the true believers, whether young or more advanced, should be untouched. But a secret poison and infection in the soul, should rob many others of purity, and afterwards of peace. The locusts had no power to hurt those who had the seal of God. God's all-powerful, distinguishing grace will keep his people from total and final apostacy. The power is limited to a short season; but it would be very sharp. In such events the faithful share the common calamity, but from the pestilence of error they might and would be safe. We collect from Scripture, that such errors were to try and prove the Christians, 1 Corinthians 11:19. And early writers plainly refer this to the first great host of corrupters who overspread the Christian church.
Commentary on Revelation 9:13-21
(Read Revelation 9:13-21)
The sixth angel sounded, and here the power of the Turks seems the subject. Their time is limited. They not only slew in war, but brought a poisonous and ruinous religion. The antichristian generation repented not under these dreadful judgments. From this sixth trumpet learn that God can make one enemy of the church a scourge and a plague to another. The idolatry in the remains of the eastern church and elsewhere, and the sins of professed Christians, render this prophecy and its fulfilment more wonderful. And the attentive reader of Scripture and history, may find his faith and hope strengthened by events, which in other respects fill his heart with anguish and his eyes with tears, while he sees that men who escape these plagues, repent not of their evil works, but go on with idolatries, wickedness, and cruelty, till wrath comes upon them to the utmost.
