2 Samuel 19:21-25 New King James Version (NKJV)

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, you sons of Zeruiah, that you should be adversaries to me today? Shall any man be put to death today in Israel? For do I not know that today I am king over Israel?”

23. Therefore the king said to Shimei, “You shall not die.” And the king swore to him.

24. Now Mephibosheth the son of Saul came down to meet the king. And he had not cared for his feet, nor trimmed his mustache, nor washed his clothes, from the day the king departed until the day he returned in peace.

25. So it was, when he had come to Jerusalem to meet the king, that the king said to him, “Why did you not go with me, Mephibosheth?”
