Then King Solomon sware by the Lord,.... To prevent his mother pressing him to have her petition granted:
saying, God do so to me, and more also; lay such and such evils upon me, and more than I care to express:
if Adonijah have not spoken this word against his own life; to his own prejudice, and even to the loss of his life; in which Solomon suggests it would issue, being a fresh overt act of treason; he knew, from what Bathsheba said, that this was his petition, and that he had spoken of this to her, and put her upon making it for him; and who no doubt related to Solomon the whole of the conversation that passed between them, and to which he seems to have some respect in his answer.
