Matthew Poole and continuators on 2 Samuel 14:2

2 And Joab sent to Tekoah , and fetcht thence a wise woman , and said unto her, I pray thee, feign thy self to be a mourner, and put on now mourning apparel, and anoint not thy self with oil , but be as a woman that had a long time mourned for the dead:

A City of Iudah, 2 Chron. 11. 5, 6. One of Ierusalem was not convenient, lest the King might know the person, or search out the business. And besides, this Woman seems to be of great eminency for her Wisdom, as the following discourse manifests.

Rather than a Man, because Women can more easily express their passions, and do sooner procure pity in their miseries, and an answer to their requests.

As they used to do when they were out of a Mourning state. See Ruth 3. 3. Matth. 6. 17.
