1 Kings 2:32-33, 44

The LORD will bring back his bloody deeds on his own head, because, without the knowledge of my father David, he attacked and killed with the sword two men more righteous and better than himself, Abner the son of Ner, commander of the army of Israel, and Amasa the son of Jether, commander of the army of Judah. So shall their blood come back on the head of Joab and on the head of his descendants forever. But for David and for his descendants and for his house and for his throne there shall be peace from the LORD forevermore.”

The king also said to Shimei, “You know in your own heart all the harm that you did to David my father. So the LORD will bring back your harm on your own head.
