Revelation 16:10

And the fifth... — Better, The fifth angel poured out his vial upon the throne (not “the seat:” see Notes on Revelation 4:10; Revelation 13:2) of the wild beast. The vials of judgment gradually dissolve the integrity and organisation of the kingdom of the wild beast. The result of the principles on which it has been based begin to show themselves: first, moral disease in individuals; then a corrupt tone of national morals spreading into the higher orders of society; then the fierce pride of vaunted light which scorches. Where these are, disorganisation is not far off; evil goes out a murderer and comes home a suicide. The retribution comes home; the throne of the world-power, the very head and centre of its authority, is smitten.

And his kingdom was full of darkness. — And his kingdom was darkened. We have the counterpart of the Egyptian plague (Exodus 10:21); there was a typical force in that ancient plague: the kingdom which boasted itself so full of light becomes darkened. When men shut out the higher light, the smoke of their own candles will soon obscure the whole heaven. When moral evil is linked with intellectual light, the moral evil will be found the stronger; for we cannot have a sunbeam without the sun. “Take heed,” said Christ, “that the light that is in thee be not darkness.” There is a light that is darkness; the progress of evil bringing about its own retribution proves this conclusively.
