1 Kings 2:5-6, 31-33

“And there is something else. You know what Joab son of Zeruiah did to me when he murdered my two army commanders, Abner son of Ner and Amasa son of Jether. He pretended that it was an act of war, but it was done in a time of peace, staining his belt and sandals with innocent blood. Do with him what you think best, but don’t let him grow old and go to his grave in peace.

“Do as he said,” the king replied. “Kill him there beside the altar and bury him. This will remove the guilt of Joab’s senseless murders from me and from my father’s family. The LORD will repay him for the murders of two men who were more righteous and better than he. For my father knew nothing about the deaths of Abner son of Ner, commander of the army of Israel, and of Amasa son of Jether, commander of the army of Judah. May their blood be on Joab and his descendants forever, and may the LORD grant peace forever to David, his descendants, his dynasty, and his throne.”
