Apocalipse 19:15

And out of his mouth... — Translate, And out of His mouth goeth a sharp sword, that with (literally, in) it He may smite the nations: and He (Himself) shall shepherd them with (literally, in) a rod of iron: and He (Himself) treadeth the winepress of the wine of the wrath of the anger of God the All ruler. The sharp sword is the same that we have read of before (Apocalipse 1:16); there it was called the two-edged sword. The omission of the epithet in this passage, which describes the Word of God as the conqueror and the judge, is not without significance. The sword is now wielded for but one work — the word that Christ spoke will judge men at the last day (João 12:48). The power of this word found an illustration in the falling back of the hostile band which came to take Him in the day of His humiliation (João 18:5); yet more gloriously will the power of His word be felt (comp. Isaías 11:4; Jeremias 23:29; 2 Tessalonicenses 2:8) when He will slay the wicked with the word of His mouth. The passage in Salmos 2:9 must be borne in mind. Christ comes as King; His is a rule in righteousness; those who oppose this kingdom of righteousness find the shepherd’s staff as a rod of iron; the stone rejected falls upon the builders, and grinds them to powder. It is thus that the winepress of God’s wrath is set up, and the righteous King appears as one who treads it out. (Comp. Isaías 63:1.) He Himself (the emphasis lies here) treads it. We have again the figure of the vintage made use of. (Comp. Apocalipse 14:20.) It is the harvest of retribution; the wicked are filled with the fruit of their own doings; so is the work seen to be the work of the All-Ruler.
