Abiathar joined David, who was then in the cave of Adullam (1 Samuel 22:20–23; 23:6). He remained with David, and became priest of the party of which he was the leader (1 Samuel 30:7). He was of great service to David, especially at the time of the rebellion of Absalom (2 Samuel 15:24, 29, 35, 20:25).
