2 Samuel 19:19-23

19and said to him, “May my lord not hold me guilty. Do not remember how your servant did wrong on the day my lord the king left Jerusalem. May the king put it out of his mind.

20For I your servant know that I have sinned, but today I have come here as the first from the tribes of Joseph to come down and meet my lord the king.”

21Then Abishai son of Zeruiah said, “Shouldn’t Shimei be put to death for this? He cursed the LORD ’s anointed.” 22David replied, “What does this have to do with you, you sons of Zeruiah? What right do you have to interfere? Should anyone be put to death in Israel today? Don’t I know that today I am king over Israel?”

23So the king said to Shimei, “You shall not die.” And the king promised him on oath.
