1 Kings 1:10-14

10but Nathan the prophet, and Benaiah, and the mighty men, and Solomon his brother, he did not invite.

11And Nathan spoke to Bathsheba the mother of Solomon, saying, Hast thou not heard that Adonijah the son of Haggith is king, and David our lord does not know [it]?

12And now, come, let me, I pray thee, give thee counsel, that thou mayest save thine own life, and the life of thy son Solomon.

13Go and get thee in to king David, and say to him, Didst not thou, my lord, O king, swear to thy handmaid saying, Solomon thy son shall reign after me, and he shall sit on my throne? why then does Adonijah reign?

14Behold, while thou yet talkest there with the king, I also will come in after thee and confirm thy words.
