In these verses we see the work going on in the appointed order. The fourth angel poured out his vial, and that fell upon the sun; that is, say some, upon some eminent prince of the popish communion, who should renounce their false religion a little while before his utter downfall; and some expect it will be the German emperor. And now what will be the consequence of this? That sun which before cherished them with warm and benign influences shall now grow hot against these idolaters, and shall scorch them. Princes shall use their power and authority to suppress them, which yet will be so far from bringing them to repentance, that it will cause them to curse God and their king, and look upward, throwing out their blasphemous speeches against the God of heaven; they will be hardened to their ruin. The fifth angel poured out his vial, Rev 16:10. And observe, 1. Where this fell - upon the seat of the beast, upon Rome itself, the mystical Babylon, the head of the antichristian empire. 2. What effect it had there: The whole kingdom of the beast was full of darkness and distress. That very city which was the seat of their policy, the source of all their learning, and all their knowledge, and all their pomp and pleasure, now becomes a source of darkness, and pain, and anguish. Darkness was one of the plagues of Egypt, and it is opposed to lustre and honour, and so forebodes the contempt and scorn to which the antichristian interest should be exposed. Darkness is opposed to wisdom and penetration, and forbodes the confusion and folly which the idolaters should discover at that time. It is opposed to pleasure and joy, and so signifies their anguish and vexation of Spirit, when their calamities thus came upon them.
