2 Samuel 16:9-10

Then said Abishai the son of Zeruiah unto the king, Why should this dead dog curse my lord the king? let me go over, I pray thee, and take off his head. And the king said, What have I to do with you, ye sons of Zeruiah? Because he curseth, and because Jehovah hath said unto him, Curse David; who then shall say, Wherefore hast thou done so?
