2 Samuel 14:18-20

18Then the king said to the woman, “I am going to ask you something; do not conceal it from me!”

“Let my lord the king speak,” she replied.

19So the king asked, “Is the hand of Joab behind 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 that my lord the king says. Yes, your servant Joab is the one who gave me orders; he told your maidservant exactly what to say. 20Joab your servant has done this to bring about this change of affairs, but my lord has wisdom like the wisdom of the angel of God, to know everything that happens in the land.”
