2 Samuel 19:19-23 - David's Mercy To Shimei
19 And he said to the king, Let not my lord impute iniquity to me, neither remember thou that which thy servant did perversely the day that my lord the king went out of Jerusalem, that the king should take it to his heart. 20 For thy servant knows that I have sinned. Therefore, behold, I have come this day the first of all the house of Joseph to go down to meet my lord the king.
21 But Abishai the son of Zeruiah answered and said, Shall not Shimei be put to death for this, because he cursed LORD's anointed?
22 And David said, What have I to do with you, ye sons of Zeruiah, that ye should this day be adversaries to me? Shall there any man be put to death this day in Israel? For do I not know that I am this day king over Israel? 23 And the king said to Shimei, Thou shall not die. And the king swore to him.
