15 So Bathsheba went into the king's bedroom. (He was very old now, and Abishag was taking care of him.) 16 Bathsheba bowed down before the king. "What can I do for you?" he asked her. 17 She replied, "My lord, you made a vow before the Lord your God when you said to me, 'Your son Solomon will surely be the next king and will sit on my throne.' 18 But instead, Adonijah has made himself king, and my lord the king does not even know about it. 19 He has sacrificed many cattle, fattened calves, and sheep, and he has invited all the king's sons to attend the celebration. He also invited Abiathar the priest and Joab, the commander of the army. But he did not invite your servant Solomon. 20 And now, my lord the king, all Israel is waiting for you to announce who will become king after you. 21 If you do not act, my son Solomon and I will be treated as criminals as soon as my lord the king has died."

Observe Nathan's address to Bathsheba. Let me give thee counsel how to save thy own life, and the life of thy son. Such as this is the counsel Christ's ministers give us in his name, to give all diligence, not only that no man take our crown, Revelation 3:11, but that we save our lives, even the lives of our souls. David made a solemn declaration of his firm cleaving to his former resolution, that Solomon should be his successor. Even the recollection of the distresses from which the Lord redeemed him, increased his comfort, inspired his hopes, and animated him to his duty, under the decays of nature and the approach of death.
