Now King David was old, &c.— It appears from 2 Samuel 5:4-5 that he was seventy years old. The strength of nature was so far abated in him, that clothes could not keep him warm in his bed. His physicians therefore advised, that a fair and youthful virgin should be sought for, who might cherish his vital heat; the natural warmth of a young healthful human body being, as the physicians observe, best fitted for that end, both in kind and degree. If it be asked, how the beauty of the person to be employed for this purpose was concerned in David's health; I answer, that the beauty here required, is evidently beauty of complexion, which, as it indicates the health and temperament of the body, might be of importance in this case. Possibly too, as David was very beautiful himself, they sought for some person of complexion and constitution likest to his own, and, of consequence, best suited, and most congenial to it. Scheuchzer, on the place, has entered philosophically into the subject; to him, therefore, we refer. We should remark, however, that concubinage was not at that time deemed criminal; and it will I hope, says Dr. Delaney, be thought no wild paradox, to venture to surmise, that a man can with less reluctance suffer his infirmities to be relieved by a wife, than by any other mortal.
Note; (1.) They who come to old age, must expect the burden of infirmities which attend it. (2.) Though the candle of life escape the furious blasts of disease or accident, it must shortly burn out of itself. (3.) The view of approaching old age and death should enliven our diligence to work for God, whilst life and strength are with us.
