2 Samuel 16:5-13

When King David came to Bahurim, behold, there came out from there a man of the family of the house of Saul whose name was Shimei, the son of Gera; he came out cursing continually as he came. He threw stones at David and at all the servants of King David; and all the people and all the mighty men were at his right hand and at his left. Thus Shimei said when he cursed, “Get out, get out, you man of bloodshed, and worthless fellow! The LORD has returned upon you all the bloodshed of the house of Saul, in whose place you have reigned; and the LORD has given the kingdom into the hand of your son Absalom. And behold, you are taken in your own evil, for you are a man of bloodshed!” Then Abishai the son of Zeruiah said to the king, “Why should this dead dog curse my lord the king? Let me go over now and cut off his head.” But the king said, “What have I to do with you, O sons of Zeruiah? If he curses, and if the LORD has told him, ‘Curse David,’ then who shall say, ‘Why have you done so?’ ” Then David said to Abishai and to all his servants, “Behold, my son who came out from me seeks my life; how much more now this Benjamite? Let him alone and let him curse, for the LORD has told him. Perhaps the LORD will look on my affliction and return good to me instead of his cursing this day.” So David and his men went on the way; and Shimei went along on the hillside parallel with him and as he went he cursed and cast stones and threw dust at him.
