1 Kings 2:32-34

32The Lord will repay him for the slaughter he caused. Joab killed two honorable men who were better than he was. He used his sword to kill Abner (who was the son of Ner and the commander of Israel’s army) and Amasa (who was the son of Jether and the commander of Judah’s army). Joab did this without my father’s knowledge.

33The responsibility for their blood will fall on Joab and his descendants forever. But may David, his descendants, family, and throne always receive peace from the Lord.”

34Then Benaiah, son of Jehoiada, went and attacked Joab, killed him, and buried him at his home in the desert.
