1 Kings 1:10-12

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.
