“And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.”
King James Version (KJV)
19:21 Here is a most magnificent description of the overthrow of the beast and his adherents. It has, in particular, one exquisite beauty; that, after exhibiting the two opposite armies, and all the apparatus for a battle, verses 11 - 19; #Rev 19:11 |- 19 then follows immediately, verse 20, #19:20| the account of the victory, without one word of an engagement or fighting. Here is the most exact propriety; for what struggle can there be between omnipotence, and the power of all the creation united against it! Every description must have fallen short of this admirable silence.
Re 19:21 And the remnant were slain with the sword of him that sat upon the horse. This is probably symbolic. If these who had been sinners and supporters of the powers of evil were incapacitated for that support longer, it would be their death (separation) from that cause. It may be that this remnant were converted by the word. And all the fowls were filled with their flesh. If this is a symbol its signification is that the victory was complete.
