5. ἐπιστάτα. The word is not Rabbi as in the other Evangelists,—a word which Gentiles would not have understood but Ἐπιστάτα (in its occasional classic sense of ‘teacher’) which is peculiar to St Luke (Luk 5:5, Luk 8:24; Luk 8:45, Luk 9:33; Luk 9:49, Luk 17:13), who never uses Rabbi. These are the only places where it occurs.
