Matthew Poole and continuators on Revelation 19:21

In all Armies there are common Souldiers as well as Officers. What the Issue of this Battel shall be, as to the Leaders in it, the former Verse told us: This tells us how it shall fare with those under the Command of them.

And this bloody Day (when ever it comes) will be a Day of great Slaughter; for the dead Bodies will be enough to sup and fill all the Fowls of Heaven.
