1 Kings 2:20-22

20“I’m asking you for one little thing,” she said. “Don’t refuse me.” “Ask, Mother,” the king told her. “I won’t refuse you.”

21She replied, “Let Abishag from Shunem be given to your brother Adonijah as his wife.”

22King Solomon then said, “Why do you ask that Abishag from Shunem be given to Adonijah? That would be the same as giving him the kingship. After all, he is my older brother. The priest Abiathar and Joab (Zeruiah’s son) are supporting him.”
