1 Kings 2:31-34

31The king said to him, “Do just as he says. Strike him down and bury him in order to remove from me and from my father’s family the blood that Joab shed without just cause.

32The Lord will bring back his own blood on his head because he struck down two men more righteous and better than he, without my father David’s knowledge. With his sword, Joab murdered Abner son of Ner, commander of Israel’s army, and Amasa son of Jether, commander of Judah’s army.

33The responsibility for their deaths will come back to Joab and to his descendants forever, but for David, his descendants, his dynasty, and his throne, there will be peace from the Lord forever.”

34Benaiah son of Jehoiada went up, struck down Joab, and put him to death. He was buried at his house in the wilderness.
