1 Kings 2:20-22

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.
