2 Samuel 19:21

18 And there went over a ferry-boat to carry over the king's household, and to do what he thought good. And Shimei the son of Gera fell down before the king, as he came over Jordan;

19 And said to the king, Let not my lord impute iniquity to me, neither do thou remember 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 doth know that I have sinned: therefore behold, I have come the first this day 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 the 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 not I know that I [am] this day king over Israel?

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

24 And Mephibosheth the son of Saul came down to meet the king, and had neither dressed his feet, nor trimmed his beard, nor washed his clothes, from the day the king departed until the day he came [again] in peace.
