1 Kings 1:49 - Ellicott's Commentary On The Whole Bible

And all the guests. — Nothing is more striking than the sudden and humiliating collapse of the attempt of Adonijah, strongly supported as it was by Joab and Abiathar, in contrast with the formidable character of the rebellion of Absalom. This is another indication that the royal power had been greatly consolidated during the last peaceful years of David’s reign. Perhaps, moreover, the usurpation of Adonijah, not being viewed as a rebellion against David, but only a presumption on his favour, was accordingly crushed at once by the expression of his will. It is strange that of all the conspirators Adonijah alone seems to have feared punishment at this time; his accomplices, the other conspirators, are apparently allowed to disperse in safety, and their rebellion is ignored.
