Charles Ellicott Commentary 2 Samuel 14:2

"And Joab sent to Tekoa, and fetched thence a wise woman, and said unto her, I pray thee, feign thyself to be a mourner, and put on mourning apparel, I pray thee, and anoint not thyself with oil, but be as a woman that hath a long time mourned for the dead:" — 2 Samuel 14:2 (ASV)

Tekoah. —A village on a high hill five miles south of Bethlehem, the home of the prophet Amos. It was also the native place of Ira, one of David’s thirty heroes (2 Samuel 23:26), and was near enough to Bethlehem, the home of Joab, for him to have had personal knowledge of this “wise woman.” There is no ground whatever for suspecting her of being a “witch,” or in any way disreputable.

The parable that follows was contrived by Joab, yet also required skill and address on the part of the woman. It is purposely made not too closely parallel to the case of Absalom, so that it would not defeat its own object. In general it needs no comment.
