2 Samuel 16:11-13

Then 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. And perhaps the LORD will see that I am being wronged and will bless me because of these curses today.” So David and his men continued down the road, and Shimei kept pace with them on a nearby hillside, cursing and throwing stones and dirt at David.
