Revelation 20:1
Revelation 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.
