Mark 2:26

(ubi sup.) There is, however, no discrepancy, for both were there, when David came to ask for bread, and received it: that is to say, Abimelech, the High Priest, and Abiathar his son; but Abimelech having been slain by Saul, Abiathar fled to David, and became the companion of all his exile afterwards. When he came to the throne, he himself also received the rank of High Priest, and the son became of much greater excellence than the father, and therefore was worthy to be mentioned as the High Priest, even during his fathers life-time.

(Vict. Ant. e Cat. in Marc.) But our Lord brings forward David, to whom it once happened to eat though it was forbidden by the law, when he touched the Priest's food, that by his example, he might do away with their accusation of the disciples. For there follows, Have ye never read, &c.

For David, when flying from the face of Saul, went to the Chief Priest, and ate the show-bread, and took away the sword of Goliath, which things had been offered to the Lord. (1 Sam. 21.) But a question has been raised how the Evangelist called Abiathar at this time High Priest, when the Book of Kings calls him Abimelech. Or else, because when they hare rest from their passions, then are they made doctors to lead others to virtue, plucking away from them earthly things.
