Barnes' Notes
And out of his mouth goeth a sharp sword - See the notes on Revelation 1:16. In that place the sword seems to be an emblem of his words or doctrines, as penetrating the hearts of people; here it is the emblem of a work of destruction worked on his foes.
That with it he should smite the nations - The nations that were opposed to him; to wit, those especially who were represented by the beast and the false prophet, Revelation 19:18-20.
And he shall rule them with a rod of iron - See the notes on Revelation 2:27; Revelation 12:5.
And he treadeth the wine-press of the fierceness and wrath of Almighty God - This language is probably derived from Isaiah 63:1-4. See it explained in the notes on that place, and on Revelation 14:19-20. It means here that his enemies would be certainly crushed before him - as grapes are crushed under the feet of him that treads in the winevat.
