1 Kings 2:17-25

17And he said, Speak, I pray thee, to Solomon the king, (for he will not say to thee no,) that he give me Abishag the Shunammite for a wife. 18And Bathsheba said, Well; I will speak for thee to the king. 19Bathsheba therefore 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 caused a seat 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; I pray thee, deny me not. And the king said to her, Ask on, my mother: for I will not deny thee. 21And she said, Let Abishag the Shunammite be given to Adonijah thy brother for a 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 my elder brother; even for him, and for Abiathar the priest, and for Joab the son of Zeruiah. 23Then king Solomon swore by the LORD, saying, God do so to me, and more also, if Adonijah hath not spoken this word against his own life. 24Now therefore, as the LORD liveth, who 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.
