1 Kings 2:5

Moreover you know all that Joab the son of Saruia did to me, what he did to the two captains of the forces of Israel, to Abenner the son of Ner, and to Amessai the son of Jether, that he killed them, and shed the blood of war in peace, and put innocent blood on his girdle that was about his loins, and on his sandal that was on his foot.
