2 Samuel 19:22-26

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.

And it was when he came from Jerusalem to meet the king, that the king said to him, “Why did you not go with me, Mephibosheth?”

So he said, “My lord the king, my servant betrayed me; for your servant said, ‘I will saddle the donkey for myself so that I may ride on it and go with the king,’ since your servant cannot walk.
