2 Samuel 14:2-3

2So he sent a message to Tekoa to bring a wise woman from there. He said to her, ‘Pretend that you are upset because of someone's death. Dress in funeral clothes. Do not use any perfume on your body. You must seem like a woman who has been sad for a long time.

3Then go to the king to speak to him.’ Then Joab told her the words that she should speak to the king.
