2 Samuel 14:17-20

17Then your maidservant said, ‘Please let the word of my lord the king be comforting, for my lord the king is as the angel of God to discern good and evil. May the Lord your God be with you.’ ”

18Then the king answered and said to the woman, “Do not hide from me anything that I ask you.” And the woman said, “Let my lord the king please speak.”

19The king said, “Is the hand of Joab with you in all of this?” And the woman answered, “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 said. Indeed, it was your servant Joab who commanded me; he put all these words in the mouth of your maidservant.

20In order to change the appearance of things [between Absalom and you, his father] your servant Joab did this thing. But my lord has wisdom like the wisdom of the angel of God, to know everything that is in the earth.”
