2 Samuel 14:2, 19-20

So Joab sent word to Tekoa and had a wise woman brought from there and told her, “Please pretend to be a mourner, and put on mourning clothes, and do not anoint yourself with oil, but act like a woman who has for many days been in mourning for the dead.

The king said, “Is the hand of Joab with you in all of this?” And the woman answered, “As your soul lives, my lord the king, no one can turn to the right or to the left from anything that my lord the king has said. Indeed, it was your servant Joab who commanded me; he put all these words in the mouth of your maidservant. In order to change the appearance of things [between Absalom and you, his father] your servant Joab did this thing. But my lord has wisdom like the wisdom of the angel of God, to know everything that is in the earth.”
