Revelation 19:21

“And the remnant were slain, etc.] Not only the kings of the earth, and their armies, that will now be gathered together, but all the remains of Papists, Pagans, and Mahometans, in the several parts of the world, even all the enemies of Christ: these will be slain with the sword of him that sat upon the horse; upon the white horse, as the Ethiopic version reads; the Arabic version reads, that sat upon the throne, which sword proceedeth out of his mouth, (<661915>Revelation 19:15) and is the word of God, or the judiciary sentence of Christ according to it; and the meaning is, either that these shall be subdued, conquered, and converted by the word; and so are fitly called a “remnant”, a…”

“the remnant: Rev 19:11-15, Rev 1:16 and all: Rev 19:17, Rev 19:18, Rev 17:16 Next: Revelation Chapter 20”
