2 Samuel 19:21-25

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?

And David said, What have I to do with you, ye sons of Zeruiah, that ye should this day be adversaries unto 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?

Therefore the king said unto Shimei, Thou shalt not die. And the king sware unto him.

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.

And it came to pass, when he was come to Jerusalem to meet the king, that the king said unto him, Wherefore wentest not thou with me, Mephibosheth?
