1 Kings 2:28-31

28When the news reached Joab, who had conspired with Adonijah though not with Absalom, he fled to the tent of the LORD and took hold of the horns of the altar.

29King Solomon was told that Joab had fled to the tent of the LORD and was beside the altar. Then Solomon ordered Benaiah son of Jehoiada, “Go, strike him down!”

30So Benaiah entered the tent of the LORD and said to Joab, “The king says, ‘Come out!’ ” But he answered, “No, I will die here.” Benaiah reported to the king, “This is how Joab answered me.” 31Then the king commanded Benaiah, “Do as he says. Strike him down and bury him, and so clear me and my whole family of the guilt of the innocent blood that Joab shed.
