2 Samuel 14:2, 19, 20

So Joab sent someone to Tekoa and had a wise woman brought from there. He said to her, “Pretend you are in mourning. Dress in mourning clothes, and don’t use any cosmetic lotions. Act like a woman who has spent many days grieving for the dead.

The king asked, “Isn’t the hand of Joab with you in all this?” The woman answered, “As surely as you live, my lord the king, no one can turn to the right or to the left from anything my lord the king says. Yes, it was your servant Joab who instructed me to do this and who put all these words into the mouth of your servant.

Your servant Joab did this to change the present situation. My lord has wisdom like that of an angel of God—he knows everything that happens in the land.”
