1Ki 1:7
He conferred (for the expression, compare 2Sa 3:17) with Joab and Abiathar the priest, who supported him. אהרי עזר, to lend a helping hand to a person, i.e., to support him by either actually joining him or taking his part. Joab joined the pretender, because he had fallen out with David for a considerable time (cf. 1Ki 2:5-6), and hoped to secure his influence with the new king if he helped him to obtain possession of the throne. But what induced Abiathar the high priest (see at 2Sa 8:17) to join in conspiracy with Adonijah, we do not know. Possibly jealousy of Zadok, and the fear that under Solomon he might be thrown still more into the shade. For although Zadok was only high priest at the tabernacle at Gibeon, he appears to have taken the lead; as we may infer from the fact that he is always mentioned before Abiathar (cf. 2Sa 8:17; 2Sa 20:25, and 2Sa 15:24.). For we cannot imagine that Joab and Abiathar had supported Adonijah as having right on his side (Thenius), for the simple reason that Joab did not trouble himself about right, and for his own part shrank from no crime, when he thought that he had lost favour with the king.
