Proverbs 3:16-18

Length of days is in her right hand— The wise man represents wisdom (i.e. holiness or religion) as other authors have done, particularly the excellent Cebes, in the shape of a beautiful woman, or rather queen; with her arms extended, in the posture not only of directing, but also of rewarding, her lovers and followers; for she holds forth in her right hand the great blessing of health and length of days, unto all those who will walk in the way to which she points; and it was but just to place this in her right hand; i.e. to give it the precedence, because it was the chief temporal promise of the law, and indeed the most desirable of all earthly blessings. After this follow wealth and reputation; which he places in her left hand, as inferior blessings, but which proceed also from her gift. Spiritually, these blessings refer to eternity, and the glories of heaven. As for cheerfulness in all conditions, there are no pleasures, he affirms, like those which wait upon wisdom and attend her motions; safe and secure pleasures; which do not merely gratify us for the present, and then expose us to danger, and leave us to the corrosives of sad reflections; but which give us a peaceable possession of perpetual joy, which never dies or decays, but, like the tree of life, remains fresh for ever. This allusion to the tree of life seems to be proverbial for that which prolongs life, and makes it pleasant and delightful. Some of the fathers understand it of Christ and his doctrine; and it is literally true, that he gives immortality, as the tree of life in paradise would have done. See Bishop Patrick.
