Charles Ellicott Commentary Revelation 7:13

"And one of the elders answered, saying unto me, These that are arrayed in white robes, who are they, and whence came they?" — Revelation 7:13 (ASV)

And one of the elders answered, saying to me.—The seer had asked no question, but the elder answers the wondering thoughts and questionings which fill his mind. Perhaps this scene was in Dante’s mind when he described himself in Paradise:

“Silent was I, yet desire
Was painted in my looks; and thus I spoke
My wish more earnestly than language could.”
—Paradiso, iv. 10-12.

The elder asks the question which he knows St. John would wish to ask: These who are clothed in white robes, who are they, and from where did they come? The question brings the white robes into prominence.

Is it, as has been suggested, that the wonder of the seer is excited more by the emblem of holiness and innocence than anything else? He recognises the multitudes as men and women out of every nation and tribe of sinful humanity, and he sees them clothed in the garb of holiness. Who are these countless throngs of holy ones?
