1 Kings 2:28-31

28Now the news reached Joab, for Joab had supported and followed Adonijah, although he had not followed Absalom. So Joab fled to the [sacred] tent of the Lord and took hold of the horns of the altar [to seek asylum].

29King Solomon was told that Joab had fled to the tent of the Lord and was at that moment beside the altar. Then Solomon sent Benaiah the son of Jehoiada, saying, “Go, strike him down.”

30So Benaiah came to the tent of the Lord and told Joab, “This is what the king commands, ‘Come out of there.’ ” But Joab said, “No, for I will die here.” Then Benaiah brought word to the king again, saying, “This is what Joab said, and this is how he answered me.”

31The king said to him, “Do as he has said. Strike him down and bury him, so that you may remove from me and from my father’s house the innocent blood which Joab shed.
