2 Samuel 14:1-3

Now Joab the son of Zeruiah perceived that the king’s heart was drawn toward Absalom.

So Joab sent a messenger to Tekoa and brought a wise woman from there, and said to her, “Please follow mourning rites, and put on mourning garments now, and do not anoint yourself with oil but be like a woman who has been mourning for the dead for many days.

Then go to the king and speak to him in this way.” So Joab put the words in her mouth.
