In all armies there are are common soldiers as well as officers. What the issue of this battle 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 all the fowls were filled with their flesh; and this bloody day (whenever 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.
