1 Kings 2:15, 22-24

“You remember that at one time the kingdom was mine,” Adonijah said. “All the people of Israel recognized me as their king, but things have changed. Now my brother is the king, because the LORD chose him.

King Solomon answered his mother, “Why do you ask me to give him Abishag? Why don’t you also ask for him to become the king since he is my older brother? Abiathar the priest and Joab son of Zeruiah would support him!” Then King Solomon swore by the name of the LORD, saying, “May God punish me terribly if this doesn’t cost Adonijah his life! By the LORD who has given me the throne that belonged to my father David and who has kept his promise and given the kingdom to me and my people, Adonijah will die today!”
