1 Kings 2:17-25

17And he said, Speak, I pray thee, to Solomon the king — for he will not refuse thee — that he give me Abishag the Shunammite as wife.

18And Bathsheba said, Well, I will speak for thee to the king.

19And Bathsheba went to king Solomon, to speak to him for Adonijah. And the king rose up to meet her, and bowed himself to her, and sat down on his throne; and he caused a throne to be set for the king's mother, and she sat on his right hand.

20Then she said, I desire one small petition of thee; refuse me not. And the king said to her, Ask, my mother, for I will not refuse thee.

21And she said, Let Abishag the Shunammite be given to Adonijah thy brother as wife.

22And king Solomon answered and said to 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.

23And king Solomon swore by Jehovah saying, 1God do so to me, and more also, — Adonijah has spoken this word against his own life!

24And now [as] Jehovah liveth, who has established me, and set me on the throne of David my father, and who has made me a 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; who fell on him, that he died.
