So Bathsheba went to King Solomon to talk with him about Adonijah. The king stood up to meet her and bowed low to her. Then he returned to his throne and had a throne set up for the queen mother. She sat to his right.
She said, "I have just one small request for you. Don't refuse me." The king said to her, "Mother, ask me. I won't refuse you."
"Let Abishag from Shunem be married to your brother Adonijah," she said.
King Solomon replied to his mother, "Why ask only for Abishag from Shunem for Adonijah? Why not ask for the entire kingdom for him? After all, he is my older brother and has the support of Abiathar the priest and Joab, Zeruiah's son."
King Solomon swore by the LORD, "May God do to me as he sees fit! Adonijah has made this request at the cost of his life!
Now, as surely as the LORD lives—the one who supported me, put me on the throne of my father David, and provided a royal house for me exactly as he promised—Adonijah will be executed today."
So King Solomon sent Benaiah, Jehoiada's son. He attacked Adonijah, and Adonijah died.
