1 Kings 2:5-6, 28-34

“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.

Joab had not joined Absalom’s earlier rebellion, but he had joined Adonijah’s rebellion. So when Joab heard about Adonijah’s death, he ran to the sacred tent of the LORD and grabbed on to the horns of the altar. When this was reported to King Solomon, he sent Benaiah son of Jehoiada to execute him. Benaiah went to the sacred tent of the LORD and said to Joab, “The king orders you to come out!” But Joab answered, “No, I will die here.” So Benaiah returned to the king and told him what Joab had said. “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.” So Benaiah son of Jehoiada returned to the sacred tent and killed Joab, and he was buried at his home in the wilderness.
