1 Kings 2:31-33

2:31 The king told him, “Do as he said! Strike him down and bury him. Take away from me and from my father’s family the guilt of Joab’s murderous, bloody deeds. 2:32 May the Lord punish him for the blood he shed; behind my father David’s back he struck down and murdered with the sword two men who were more innocent and morally upright than he – Abner son of Ner, commander of Israel’s army, and Amasa son of Jether, commander of Judah’s army. 2:33 May Joab and his descendants be perpetually guilty of their shed blood, but may the Lord give perpetual peace to David, his descendants, his family, and his dynasty.”
