It shall be health to thy navel
That part of the body which is the knot of the intestines; and may be put for the bowels and inward parts, which being sound, the body is in health; and these may be put for the whole body: and so the Septuagint version renders it, "to thy body"; and this may be put for the whole person. And the sense is, either wisdom, as Jarchi; the doctrine of wisdom, the Gospel; which teaches men to trust in the Lord, and not in themselves, to apply to him for wisdom, and not lean to their own understanding; this contributes much to a man's spiritual health and welfare: or else the fear of the Lord is of this use to men, both in soul and body; since by it they depart from those sins which bring diseases upon the body; and are influenced by it to the exercise of such graces, and the discharge of such duties, as are the means of keeping the soul in good plight; and marrow to thy bones;
or, "watering" F13 to them: that which irrigates and moistens them, and makes and keeps them strong and solid: see ( Job 21:24 ) . What marrow is to the bones, that is wisdom, or the fear of God, to the souls of men; the means of establishing and strengthening them against sin, and snares and temptations, and to do the will and work of God.
