1 Kings 2:22-24

New International Version - UK

²² King Solomon answered his mother, ‘Why do you request Abishag the Shunammite for Adonijah? You might as well request the kingdom for him – after all, he is my older brother – yes, for him and for Abiathar the priest and Joab son of Zeruiah!’

²³ Then King Solomon swore by the Lord: ‘May God deal with me, be it ever so severely, if Adonijah does not pay with his life for this request! ²⁴ And now, as surely as the Lord lives – he who has established me securely on the throne of my father David and has founded a dynasty for me as he promised – Adonijah shall be put to death today!’
