2 Samuel 14:2-4

2And Joab sent to Tekoah, and fetched thence a wise woman, and said to her, I pray thee, feign thyself to be a mourner, and put on mourning garments, I pray, and anoint not thyself with oil, but be as a woman that hath a long time mourned for the dead;

3and come to the king, and speak after this manner to him. And Joab put the words into her mouth.

4And the woman of Tekoah spoke to the king, and she fell on her face to the ground and did obeisance, and said, Save, O king!
