The description is taken from Isaiah 63:2, Isaiah 63:3, where Judas Maccabeus, or some other conqueror, is described.
The Word of God - Written in the Targum, and in other Jewish writings, מימרא דיי meimera daiya, "the word of Jehovah;" by which they always mean a person, and not a word spoken. See the notes on John 1:1, etc.
