2 Samuel 19:23-27

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.

Furthermore, he has slandered your servant to my lord the king; but my lord the king is like the angel of God, therefore do what is good in your sight.
