2 Samuel 19:20-23

20For thy servant knows that I have sinned; and behold, I am come the first this day of all the house of Joseph to go down to meet my lord the king.

21And Abishai the son of Zeruiah answered and said, Should not Shimei be put to death for this, because he cursed Jehovah's anointed?

22And David said, What have I to do with you, ye sons of Zeruiah, that ye should this day be adversaries to me? Should there any man be put to death this day in Israel? for do not I know that I am this day king over Israel?

23And the king said to Shimei, Thou shalt not die. And the king swore to him.
