Revelation 9:18 Revelation 9:18 By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths. This may be understood literally. By these three; that is, by the fire of the Turkish canons, killing men, and burning towns in the Roman Empire; and by the smoke; that is, the Turkish Alchoran and Mahometan religion; and by the brimstone which issued out of their mouths; that is, the powder and bullets which the Turkish horsemen shot out of the mouths of their muskets, carbines, pistols, etc. The third part of men were killed; that is, in the Roman empire, were slain and destroyed in the European wars by the Turkish armies.
