C. F. Keil and Franz Delitzsch on 1 Kings 1:11-13

1Ki 1:11-13

Nathan informed Solomon’s mother, Bathsheba (see at 2Sa 11:3), that Adonijah was making himself king (מלך כּי, that he had become as good as king: Thenius), and advised her, in order to save her life and that of her son Solomon (וּמלטי, and save = so that thou mayest save; cf. Ewald, §347, a.), to go to the king and remind him of his promise on oath, that her son Solomon should be king after him, and to inquire why Adonijah had become king. If Adonijah had really got possession of the throne, he would probably have put Solomon and his mother out of the way, according to the barbarous custom of the East, as his political opponents.
