2 Samuel 16:9-12

9Then said Abishai the son of Zeruiah to the king, Why should this dead dog curse my lord the king? let me go over, I pray thee, and take off his head. 10And the king said, What have I to do with you, ye sons of Zeruiah? so let him curse, because the LORD hath said to him, Curse David. Who shall then say, Why hast thou done so? 11And David said to Abishai, and to all his servants, Behold, my son, who came forth from my own body, seeketh my life: how much more now may this Benjamite do it ? let him alone, and let him curse; for the LORD hath bidden him. 12It may be that the LORD will look on my affliction, and that the LORD will repay me good for his cursing this day.1
