The portion of scripture which he had been reading was this: "He was led as a sheep to the slaughter; and as a lamb before him who sheareth it is dumb, so he opened not his mouth: in his humiliation his judgment was taken away: but his generation who can describe? for his life was taken away from the earth." Then the eunuch addressing himself to Philip, said, I pray thee, of whom doth the prophet thus speak? of himself, or of some other person?
