For by me thy days shall be multiplied,.... These are the words of Wisdom, and contain a reason and argument why her call and advice in the preceding verses should be listened unto, since she gives long life to her followers. She is a tree of life unto them, the author and giver of spiritual and eternal life; by means of her bread and her wine spiritual life is maintained, promoted, and preserved; and length of days, for ever and ever, is the gift of her right hand; see Pro 3:16. The Targum is, "for by it thy days shall be multiplied;'' which seems to refer it to the fear of the Lord, the beginning of wisdom, in Pro 9:10, to which long life is attributed; see Pro 10:27; and the years of thy life shall be increased; or, "they shall add years of life to thee" (o); wisdom and understanding, the fear of the Lord, and the knowledge of the Holy; if not in this world, yet in the world to come, which will be without end. (o) "et addent tibi annos vitae", Baynus, Cocceius.
