1 Kings 2:28-31

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.
