1 Kings 2:21-24
Context2:21 She said, “Allow Abishag the Shunammite to be given to your brother Adonijah as a wife.” 2:22 King Solomon answered his mother, “Why just request Abishag the Shunammite for him? 1 Since he is my older brother, you should also request the kingdom for him, for Abiathar the priest, and for Joab son of Zeruiah!”
2:23 King Solomon then swore an oath by the Lord, “May God judge me severely, 2 if Adonijah does not pay for this request with his life! 3 2:24 Now, as certainly as the Lord lives (he who made me secure, allowed me to sit on my father David’s throne, and established a dynasty 4 for me as he promised), Adonijah will be executed today!”
