9:20 {15} And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:
(15) Now remains the event (as I said on the first verse), see Geneva Re 9:1 which followed so many grievous judgments in the most wicked world, namely an impenitent affirmation of the ungodly in their impiety and unrighteousness, though they feel themselves most vehemently pressed with the hand of God: for their obstinate ungodliness is showed in this verse: and their unrighteousness in the verse following Re 9:21. So far has been the general history of things to be done universally in the whole world: which because it does not so much belong to the Church of Christ, is therefore not so expressly distinguished by certainty of time and other circumstances, but is woven, as they say, with a slight hand. Also there is no other reason why the history of the seventh angel is passed over in this place, then for that the same more properly appertains to the history of the Church. But this is more diligently set out according to its time, Re 11:16 as shall appear on those places.
9:20 The rest... repented not of the works of their hands. It is implied that these woes were sent as judgments. The Christianity of the East overthrown by the Saracens and Turks had become utterly corrupt. The rest, that is, those in other countries not conquered by Turks, continued their sins.
That they should not worship devils. The worship of dead saints is what is meant by demon worship in the Scriptures.
And idols of gold, and silver, and brass, and stone, and of wood. Images had now been introduced into the churches everywhere and were worshiped.
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.
