Revelation 19:13

And he was clothed with a vesture dipped in blood
Either in his own, by which he became the Saviour of his church and people; or else in the blood of his saints, he now comes to avenge; or rather in the blood of his enemies, with which he appears as stained, before the battle is fought, the victory being sure, and their slaughter unavoidable: the metaphor is taken from persons treading in a winepress, whose garments are stained with blood of grapes; see ( Revelation 19:15 ) ( Genesis 49:11 ) ( Isaiah 63:1-3 ) . Here may be also an allusion to the Roman general's vesture, which was sometimes purple or scarlet, in which he fought, as did Lucullus ^F19.

And his name is called the Word of God;
the name of Christ, often used by John in his Gospel, epistles, and in this book, ( John 1:1 John 1:14 ) ( 1 John 1:1 ) ( 5:7 ) ( Revelation 1:2 Revelation 1:9 ) . Of the signification, reason, and import of this name, (See Gill on John 1:1). The reason why he is called by it here may be partly to express his greatness, glory, and majesty, this being a name which principally belongs to him, is a person, as the Creator of all things, and as previous to his incarnation; and partly because all the promises of God in his word, and which are all yea, and amen in Christ, will be now shortly fulfilled.
