2 Samuel 14:18-20

18Then the king said to the woman, ‘Now I want to ask you a question. You must not hide the truth from me.’ She replied, ‘Ask me anything, sir.’

19The king asked her, ‘Is it Joab who has told you to do this?’ The woman answered, ‘My lord the king, as surely as you live, I cannot hide the truth from you. Yes, it was your servant Joab who told me what to do. He gave me the words to say.

20He did it because he wanted things to be different. But you, my lord, are as wise as one of God's angels. You know everything that happens in our land.’
