1 Kings 1:12-14

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.
