2 Samuel 19:18-23

Then they kept crossing the ford to bring over the king’s household, and to do what was good in his sight. And Shimei the son of Gera fell down before the king as he was about to cross the Jordan. So he said to the king, “Let not my lord consider me guilty, nor remember what your servant did wrong on the day when my lord the king came out from Jerusalem, so that the king would take it to heart. For your servant knows that I have sinned; therefore 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 said, “Should not Shimei be put to death for this, because he cursed the LORD’S anointed?” David then said, “What have I to do with you, O sons of Zeruiah, that you should this day be an adversary to me? Should any man be put to death in Israel today? For do I not know that I am king over Israel today?” The king said to Shimei, “You shall not die.” Thus the king swore to him.
