2 Samuel 14:18-19

18Then the king answered the woman, "Do not hide from me anything I ask you." And the woman said, "Let my lord the king speak."

19The king said, "Is the hand of Joab with you in all this?" The woman answered and said, "As surely as you live, my lord the king, one cannot turn to the right hand or to the left from anything that my lord the king has said. It was your servant Joab who commanded me; it was he who put all these words in the mouth of your servant.
