91 And the fifth angel blew his trumpet, and I saw a star fallen from heaven to earth, and he was given the key of the shaft of the bottomless pit; 2 he opened the shaft of the bottomless pit, and from the shaft rose smoke like the smoke of a great furnace, and the sun and the air were darkened with the smoke from the shaft. 3 Then from the smoke came locusts on the earth, and they were given power like the power of scorpions of the earth; 4 they were told not to harm the grass of the earth or any green growth or any tree, but only those of mankind who have not the seal of God upon their foreheads; 5 they were allowed to torture them for five months, but not to kill them, and their torture was like the torture of a scorpion, when it stings a man. 6 And in those days men will seek death and will not find it; they will long to die, and death will fly from them. 7 In appearance the locusts were like horses arrayed for battle; on their heads were what looked like crowns of gold; their faces were like human faces, 8 their hair like women's hair, and their teeth like lions' teeth; 9 they had scales like iron breastplates, and the noise of their wings was like the noise of many chariots with horses rushing into battle. 10 They have tails like scorpions, and stings, and their power of hurting men for five months lies in their tails. 11 They have as king over them the angel of the bottomless pit; his name in Hebrew is Abad'don, and in Greek he is called Apol'lyon. 12 The first woe has passed; behold, two woes are still to come.
13 Then the sixth angel blew his trumpet, and I heard a voice from the four horns of the golden altar before God, 14 saying to the sixth angel who had the trumpet, "Release the four angels who are bound at the great river Euphra'tes." 15 So the four angels were released, who had been held ready for the hour, the day, the month, and the year, to kill a third of mankind. 16 The number of the troops of cavalry was twice ten thousand times ten thousand; I heard their number. 17 And this was how I saw the horses in my vision: the riders wore breastplates the color of fire and of sapphire and of sulphur, and the heads of the horses were like lions' heads, and fire and smoke and sulphur issued from their mouths.

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.
