1 Kings 2:31-32

Then the king ordered Benaiah, “Do as he says! Kill him there and bury him. Then my family and I will be free of the guilt of Joab, who has killed innocent people. Without my father knowing it, he killed two men who were much better than he was—Abner son of Ner, the commander of Israel’s army, and Amasa son of Jether, the commander of Judah’s army. So the LORD will pay him back for those deaths.
