2 Samuel 14:2-4

2So he sent for a woman from Tekoa who had a reputation for great wisdom. He said to her, “Pretend you are in mourning; wear mourning clothes and don’t put on lotions. Act like a woman who has been mourning for the dead for a long time.

3Then go to the king and tell him the story I am about to tell you.” Then Joab told her what to say.

4When the woman from Tekoa approached the king, she bowed with her face to the ground in deep respect and cried out, “O king! Help me!”
