1 Kings 1:11-14

11Then Nathan said to Bathsheba the mother of Solomon, “Have you not heard that Adonijah son of Haggith has become king, and our lord David does not know it? 12Now please, come and let me advise you. Save your own life and the life of your son Solomon. 13Go at once to King David and say, ‘My lord the king, did you not swear to your maidservant, “Surely your son Solomon will reign after me, and he will sit on my throne”? Why then has Adonijah become king?’ 14Then, while you are still there speaking with the king, I will come in after you and confirm your words.”
