1 Kings 2:28

24Now therefore as the LORD lives, who has established me and set me on my father David’s throne, and who has made me a house as he promised, surely Adonijah shall be put to death today.”

25King Solomon sent Benaiah the son of Jehoiada; and he fell on him, so that he died.

26To Abiathar the priest the king said, “Go to Anathoth, to your own fields, for you are worthy of death. But I will not at this time put you to death, because you bore the Lord GOD’s ark before David my father, and because you were afflicted in all in which my father was afflicted.”

27So Solomon thrust Abiathar out from being priest to the LORD, that he might fulfill the LORD’s word which he spoke concerning the house of Eli in Shiloh.

28This news came to Joab; for Joab had followed Adonijah, although he didn’t follow Absalom. Joab fled to the LORD’s Tent, and held onto the horns of the altar.

29King Solomon was told, “Joab has fled to the LORD’s Tent; and behold, he is by the altar.” Then Solomon sent Benaiah the son of Jehoiada, saying, “Go, fall on him.”

30Benaiah came to the LORD’s Tent, and said to him, “The king says, ‘Come out!’” He said, “No; but I will die here.” Benaiah brought the king word again, saying, “This is what Joab said, and this is how he answered me.”

31The king said to him, “Do as he has said, and fall on him, and bury him, that you may take away the blood, which Joab shed without cause, from me and from my father’s house.

32The LORD will return his blood on his own head, because he fell on two men more righteous and better than he, and killed them with the sword, and my father David didn’t know it: Abner the son of Ner, captain of the army of Israel, and Amasa the son of Jether, captain of the army of Judah.
