Matthew Poole and continuators on Revelation 9:18

18 By these three were the third part of men killed, by the fire, and by the smoke, and by the brimstone which issued out of their mouths .

That is, a great part of Men were killed by these numerous Armies. No such devastations were ever made by any Enemies that ever appeared in the World, as by the Turks have been; nor ever were there such vast [illegible: 1 letter]reat Guns made, out of which came Fire and Smoak, and Brimstone.
