A third of mankind was killed by these three plagues—by the fire and the smoke and the brimstone that came from the mouths of the horses.

The rest of mankind, who were not killed by these plagues, did not repent even then of the works of their hands, so as to cease worshiping and paying homage to the demons and the idols of gold and of silver and of bronze and of stone and of wood, which can neither see nor hear nor walk;

And the rest were killed with the sword which came from the mouth of Him who sat on the horse, and all the birds fed ravenously and gorged themselves with their flesh.
