1 Kings 1:10-14

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

11 Why Nathan spoke to Bathsheba the mother of Solomon, saying, Have you not heard that Adonijah the son of Haggith does reign, and David our lord knows it not?

12 Now therefore come, let me, I pray you, give you counsel, that you may save your own life, and the life of your son Solomon.

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

14 Behold, while you yet talk there with the king, I also will come in after you, and confirm your words.
