Those constituting the outer coverings of the body exist in very great number, and they differ [all the way] from the face down to the feet. I have conversed with many of them on this subject. But there are those who in the life of the body stay with the literal meaning [of the Word] and constitute the outermost, filthy skin. Those, however, who also admit of deeper meanings, even though they do not understand them-yet still stay with them as if they were the outer meaning-these are the inward tunics of the skin.
