1 Kings 2:27-30
English Standard Version
28When the news came to Joab — for Joab had supported Adonijah although he had not supported Absalom — Joab fled to the tent of the Lord and caught hold of the horns of the altar.
29And when it was told King Solomon, "Joab has fled to the tent of the Lord, and behold, he is beside the altar," Solomon sent Benaiah the son of Jehoiada, saying, "Go, strike him down."
30So Benaiah came to the tent of the Lord and said to him, "The king commands, ‘Come out.’" But he said, "No, I will die here." Then Benaiah brought the king word again, saying, "Thus said Joab, and thus he answered me."
