Mark 14:20

To the anxious questioning of the disciples Mk. makes Jesus reply: one of the Twelve; he who dippeth with me in the dish. A repetition of the original declaration with variations: the Twelve for you, and dipping in the dish for eating; the former bringing out the gravity of the fact, the Twelve chosen to be Apostles of the faith, one of them the traitor of its Author; the latter narrowing the circle within which the traitor is to be found. Twelve ate with Jesus, only three or four would dip with Him. ἐμβαπτόμενος, middle, dipping with his own hand: “haec vis medii verbi,” Bengel.
