2 Samuel 14:17-20

17And your servant thought, 'The word of my lord the king will set me at rest,' for my lord the king is like the angel of God to discern good and evil. The Lord your God be with you!"

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.

20In order to change the course of things your servant Joab did this. But my lord has wisdom like the wisdom of the angel of God to know all things that are on the earth."
