SEV Biblia, Chapter 2:23
Y el rey Salomón juró por el SEÑOR, diciendo: Así me haga Dios y así me añada, que contra su vida ha hablado Adonías esta palabra.
John Gill's Bible Commentary
Ver. 23. Then King Solomon sware by the Lord , etc.] 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.
Matthew Henry Commentary
Verses 12-25 - Solomon received Bathsheba with all the respect that was owing to mother; but let none be asked for that which they ought not to grant It ill becomes a good man to prefer a bad request, or to appear in bad cause. According to eastern customs it was plain that Adonija sought to be king, by his asking for Abishag as his wife, and Solomo could not be safe while he lived. Ambitious, turbulent spirits commonl prepare death for themselves. Many a head has been lost by catching a a crown.
