1 Kings 2:19-25

19When Bathsheba went to King Solomon to speak to him for Adonijah, the king stood up to meet her, bowed down to her and sat down on his throne. He had a throne brought for the king’s mother, and she sat down at his right hand.

20“I have one small request to make of you,” she said. “Do not refuse me.” The king replied, “Make it, my mother; I will not refuse you.”

21So she said, “Let Abishag the Shunammite be given in marriage to your brother Adonijah.”

22King Solomon answered his mother, “Why do you request Abishag the Shunammite for Adonijah? You might as well request the kingdom for him—after all, he is my older brother—yes, for him and for Abiathar the priest and Joab son of Zeruiah!” 23Then King Solomon swore by the LORD : “May God deal with me, be it ever so severely, if Adonijah does not pay with his life for this request! 24And now, as surely as the LORD lives—he who has established me securely on the throne of my father David and has founded a dynasty for me as he promised—Adonijah shall be put to death today!”

25So King Solomon gave orders to Benaiah son of Jehoiada, and he struck down Adonijah and he died.
