14 saying to the sixth angel who had one trumpet, “Free the four angels who are bound at the great river Euphrates!” 15 The four angels were freed who had been prepared for that hour and day and month and year, so that they might kill one third of mankind. 16 The number of the armies of the horsemen was two hundred million [1]. I heard the number of them. 17 Thus I saw the horses in the vision, and those who sat on them, having breastplates of fiery red, hyacinth blue, and sulfur yellow; and the heads of lions. Out of their mouths proceed fire, smoke, and sulfur. 18 By these three plagues were one third of mankind killed: by the fire, the smoke, and the sulfur, which proceeded out of their mouths. 19 For the power of the horses is in their mouths, and in their tails. For their tails are like serpents, and have heads, and with them they harm. 20 The rest of mankind, who were not killed with these plagues, didn’t repent of the works of their hands, that they wouldn’t worship demons, and the idols of gold, and of silver, and of brass, and of stone, and of wood; which can neither see, nor hear, nor walk. 21 They didn’t repent of their murders, nor of their sorceries, [2] nor of their sexual immorality, nor of their thefts.

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.
