or rather this designs his own skin, and may be rendered, "skin upon skin", or "skin even unto skin", or "skin within skin" ; for man has two skins, an inward and an outward one, called the "cutis" and "cuticula", "derma" and "epidermis"; the latter is of a whitish colour, and is properly the covering of the skin, is very thin, and void of sensation , which may be raised up by a blister, and taken off without pain; but the other is reddish, and very sensible of pain, and cannot be taken off without putting a man to the most exquisite misery; and yet a man will part with both skins, and if he had ever so many, or he willing to be put to the greatest torment, rather than part with his life: and to this one point all the above senses, and others given by interpreters, tend, namely, to observe how precious the life of man is to him; and if this was all that Satan meant, it is very trite; but he seems to insinuate something more, and that is, that any man, and so Job though reckoned a good man, would not only part with all the skins he had, and the substance he was possessed of, to save his life, but he would part with his God, and his religion, and the profession of it, for the sake of it, which is false; for there is something more valuable than life to good men; they reckon the loving kindness of God better than life, and would sooner lose their lives than risk the danger of losing their interest in it; and are willing to part with their lives for the sake of God and true religion, for the sake of Christ and his Gospel, and for his cause and interest, as many have done.
