1 Kings 1:10-14

10But Nathan the prophet, and Benaiah, and the mighty men, and Solomon his brother, he called not.

11Therefore Nathan spoke to Bathsheba the mother of Solomon, saying, Hast thou not heard that Adonijah the son of Haggith doth reign, and David our lord knoweth it not? 12Now therefore come, let me, I pray thee, give thee counsel, that thou mayest save thy own life, and the life of thy son Solomon. 13Go and enter in to king David, and say to him, Didst not thou, my lord, O king, swear to thy handmaid, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne? why then doth Adonijah reign? 14Behold, while thou art yet talking there with the king, I will also come in after thee, and confirm thy words.1
