1 Kings 2:26

22And king Solomon answered and said unto his mother, And why dost thou ask Abishag the Shunammite for Adonijah? ask for him the kingdom also; for he is mine elder brother; even for him, and for Abiathar the priest, and for Joab the son of Zeruiah.

23Then king Solomon sware by the Lord, saying, God do so to me, and more also, if Adonijah have not spoken this word against his own life.

24Now therefore, as the Lord liveth, which hath established me, and set me on the throne of David my father, and who hath made me an house, as he promised, Adonijah shall be put to death this day.

25And king Solomon sent by the hand of Benaiah the son of Jehoiada; and he fell upon him that he died.

26And unto Abiathar the priest said the king, Get thee to Anathoth, unto thine own fields; for thou art worthy of death: but I will not at this time put thee to death, because thou barest the ark of the Lord God before David my father, and because thou hast been afflicted in all wherein my father was afflicted.

27So Solomon thrust out Abiathar from being priest unto the Lord; that he might fulfil the word of the Lord, which he spake concerning the house of Eli in Shiloh.

28Then tidings came to Joab: for Joab had turned after Adonijah, though he turned not after Absalom. And Joab fled unto the tabernacle of the Lord, and caught hold on the horns of the altar.

29And it was told king Solomon that Joab was fled unto the tabernacle of the Lord; and, behold, he is by the altar. Then Solomon sent Benaiah the son of Jehoiada, saying, Go, fall upon him.

30And Benaiah came to the tabernacle of the Lord, and said unto him, Thus saith the king, Come forth. And he said, Nay; but I will die here. And Benaiah brought the king word again, saying, Thus said Joab, and thus he answered me.
