1 Kings 2:28-29

2:28 When the news reached Joab (for Joab had supported Adonijah, although he had not supported Absalom), he ran to the tent of the Lord and grabbed hold of the horns of the altar. 2:29 When King Solomon heard that Joab had run to the tent of the Lord and was right there beside the altar, he ordered Benaiah son of Jehoiada, “Go, strike him down.”
