1 Kings 2:31-34

31“Do as he said,” the king replied. “Kill him there beside the altar and bury him. This will remove the guilt of Joab’s senseless murders from me and from my father’s family.

32The Lord will repay him for the murders of two men who were more righteous and better than he. For my father knew nothing about the deaths of Abner son of Ner, commander of the army of Israel, and of Amasa son of Jether, commander of the army of Judah.

33May their blood be on Joab and his descendants forever, and may the Lord grant peace forever to David, his descendants, his dynasty, and his throne.”

34So Benaiah son of Jehoiada returned to the sacred tent and killed Joab, and he was buried at his home in the wilderness.
