12 Solomon became king and sat on the throne of David his father, and his kingdom was firmly established.
13 One day Adonijah, whose mother was Haggith, came to see Bathsheba, Solomon's mother. "Have you come with peaceful intentions?" she asked him. "Yes," he said, "I come in peace. 14 In fact, I have a favor to ask of you." "What is it?" she asked. 15 He replied, "As you know, the kingdom was rightfully mine; all Israel wanted me to be the next king. But the tables were turned, and the kingdom went to my brother instead; for that is the way the Lord wanted it. 16 So now I have just one favor to ask of you. Please don't turn me down." "What is it?" she asked. 17 He replied, "Speak to King Solomon on my behalf, for I know he will do anything you request. Ask him to let me marry Abishag, the girl from Shunem." 18 "All right," Bathsheba replied. "I will speak to the king for you." 19 So Bathsheba went to King Solomon to speak on Adonijah's behalf. The king rose from his throne to meet her, and he bowed down before her. When he sat down on his throne again, the king ordered that a throne be brought for his mother, and she sat at his right hand. 20 "I have one small request to make of you," she said. "I hope you won't turn me down." "What is it, my mother?" he asked. "You know I won't refuse you." 21 "Then let your brother Adonijah marry Abishag, the girl from Shunem," she replied. 22 "How can you possibly ask me to give Abishag to Adonijah?" King Solomon demanded. "You might as well ask me to give him the kingdom! You know that he is my older brother, and that he has Abiathar the priest and Joab son of Zeruiah on his side." 23 Then King Solomon made a vow before the Lord : "May God strike me and even kill me if Adonijah has not sealed his fate with this request. 24 The Lord has confirmed me and placed me on the throne of my father, David; he has established my dynasty as he promised. So as surely as the Lord lives, Adonijah will die this very day!"

(Read 1 Kings 2:12-25)
Solomon received Bathsheba with all the respect that was owing to a mother; but let none be asked for that which they ought not to grant. It ill becomes a good man to prefer a bad request, or to appear in a bad cause. According to eastern customs it was plain that Adonijah sought to be king, by his asking for Abishag as his wife, and Solomon could not be safe while he lived. Ambitious, turbulent spirits commonly prepare death for themselves. Many a head has been lost by catching at a crown.
