2 Samuel 16:9-10

16:9 Then Abishai son of Zeruiah said to the king, “Why should this dead dog curse my lord the king? Let me go over and cut off his head!” 16:10 But the king said, “What do we have in common, you sons of Zeruiah? If he curses because the Lord has said to him, ‘Curse David!’, who can say to him, ‘Why have you done this?’”
