2 Samuel 19:20-24

For your servant knows that I have sinned; so behold, I have come today, the first of all the house of Joseph to go down to meet my lord the king.”

But Abishai the son of Zeruiah responded, “Should Shimei not be put to death for this, the fact that he cursed the Lord’s anointed?”

David then said, “What is there between you and me, you sons of Zeruiah, that you should be an adversary to me today? Should anyone be put to death in Israel today? For do I not know that I am king over Israel today?”

So the king said to Shimei, “You shall not die.” The king also swore to him.

Then Mephibosheth the grandson of Saul came down to meet the king; but he had neither tended to his feet, nor trimmed his mustache, nor washed his clothes since the day the king departed until the day he came home in peace.
