1 Kings 2:22-24

21st Century King James Version

²² And King Solomon answered and said unto his mother, “And why dost thou ask Abishag the Shunammite for Adonijah? Ask for him the kingdom also, for he is mine elder brother — even for him, and for Abiathar the priest, and for Joab the son of Zeruiah.”

²³ Then King Solomon swore by the Lord, saying, “God do so to me, and more also, if Adonijah have not spoken this word against his own life.

²⁴ Now therefore, as the Lord liveth, who hath established me and set me on the throne of David my father, and who hath made me a house, as He promised, Adonijah shall be put to death this day.”
