1 Kings 2:28-29

28Now the news came to Joab 1because Joab had followed Adonijah, 2though he had not followed Absalom. So Joab fled to the tent of the Lord and 3took hold of the horns of the altar.

29And it was reported to King Solomon that Joab had fled to the tent of the Lord, and 4was beside the altar. Then Solomon 5sent Benaiah the son of Jehoiada, saying, “6Go, 7execute him.”
