Who is this? The prophet opens the dialogue with an inquiry, "Who is it that presents himself before him suddenly in a strange guise?" He comes from Edom, from Bozrah—a principal Edomite city (see the comment on Isaiah 34:6)—with dyed garments; or, rather, with blood-red garments—garments incarnadined with gore.
"Who is this," again he asks, "that is glorious (or, splendid) in his apparel"—the blood-stained vesture of the conqueror was a glory to him (Nahum 2:3; Revelation 19:13)—"as he travels" (or, "bends forward" ) in the greatness of his strength—exhibiting in his movements a mighty indomitable strength?
Who is it? The reply is immediate—I that speak in righteousness, mighty to save; i.e. I, whose every word is "holy, just, and true," who alone am able to "save to the uttermost all that come to me" (Hebrews 7:25).
The answer unmistakably indicates that the figure which has appeared to the prophet is that of Jehovah.
