2 Samuel 14:2, 19-20

So Joab sent to Tekoa and brought a wise woman from there and said to her, “Please pretend to be a mourner, 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 many days

So the king said, “Is the hand of Joab with you in all this?” And the woman replied, “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 spoken. Indeed, it was your servant Joab who commanded me, and it was he who put all these words in the mouth of your maidservant; in order to change the appearance of things your servant Joab has done this thing. But my lord is wise, like the wisdom of the angel of God, to know all that is in the earth.”
