2 Samuel 16:9-12

9“Why should this dead dog curse my lord the king?” Abishai son of Zeruiah demanded. “Let me go over and cut off his head!”

10“No!” the king said. “Who asked your opinion, you sons of Zeruiah! If the Lord has told him to curse me, who are you to stop him?”

11Then David said to Abishai and to all his servants, “My own son is trying to kill me. Doesn’t this relative of Saul have even more reason to do so? Leave him alone and let him curse, for the Lord has told him to do it.

12And perhaps the Lord will see that I am being wronged and will bless me because of these curses today.”
