1 Kings 2:5-6, 31-33

“And don’t forget what Joab son of Zeruiah did to the two commanders of Israel’s army, to Abner son of Ner and to Amasa son of Jether. He murdered them in cold blood, acting in peacetime as if he were at war, and has been stained with that blood ever since. Do what you think best with him, but by no means let him get off scot-free—make him pay.

The king said, “Go ahead then, do what he says: Kill him and bury him. Absolve me and my father’s family of the guilt from Joab’s senseless murders. GOD is avenging those bloody murders on Joab’s head. Two men he murdered, men better by far than he ever was: Behind my father’s back he brutally murdered Abner son of Ner, commander of Israel’s army, and Amasa son of Jether, commander of Judah’s army. Responsibility for their murders is forever fixed on Joab and his descendants; but for David and his descendants, his family and kingdom, the final verdict is GOD’s peace.”
