1 Kings 2:31-32

The king said to him, “Do as he has said. Strike him down and bury him, so that you may remove from me and from my father’s house the innocent blood which Joab shed. The LORD will return his bloody deeds upon his own head, because he struck down two men more righteous and honorable than he and killed them with the sword, without my father David knowing: Abner the son of Ner, commander of the army of Israel, and Amasa the son of Jether, commander of the army of Judah.
