2 Samuel 16:9-13

9Then 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.

10And the king said, What have I to do with you, ye sons of Zeruiah? Because he curseth, and because the LORD hath said unto him, Curse David; who then shall say, Wherefore hast thou done so?

11And David said to Abishai, and to all his servants, Behold, my son, which came forth of my bowels, seeketh my life: how much more may this Benjamite now do it? let him alone, and let him curse; for the LORD hath bidden him.

12It may be that the LORD will look on the wrong done unto me, and that the LORD will requite me good for his cursing of me this day.

13So David and his men went by the way: and Shimei went along on the hill side over against him, and cursed as he went, and threw stones at him, and cast dust.
