1 Kings 2:5; 1 Kings 2:34

5 “Now you yourself know what Joab son of Zeruiah did to me—what he did to the two commanders of Israel’s armies, Abner son of Ner and Amasa son of Jether. He killed them, shedding their blood in peacetime as if in battle, and with that blood he stained the belt around his waist and the sandals on his feet.

34 So Benaiah son of Jehoiada went up and struck down Joab and killed him, and he was buried at his home out in the country.
