Mark 2:26

ἐπὶ Ἀβιάθαρ ἀρ.: under A., a note of time, also implying his sanction: the sanction of a distinguished sacerdotal character = of Abiathar as priest. But Ahimelech was the priest then (1 Samuel 21:2 f.). Either a natural error arising from the close connection of David with Abiathar, the well-known high priest, or we must adopt one or other of the solutions proposed: father and son, Ahimelech and Abiathar, both bore both names (1 Samuel 22:20; 2 Samuel 8:17; 1 Chronicles 18:16) so the Fathers; Abiathar, the son, Ahimelech's assistant at the time, and mentioned as the more notable as approving of the conduct of his own father and of David (Grotius); ἐπὶ taken in the sense it bears in Mark 12:26 (ἐπὶ βάτου) in the passage about Abiathar not a satisfactory suggestion.
