“ But it is doubtful whether Jesus ever used the term for the Twelve, in relation to their temporary missions, any more than for the “seventy others” whom he “sent forth” later (Luke x. 1) . Even the Fourth Gospel never so describes them. It simply has “a servant is not greater than his lord, neither an apostle (envoy) greater than he that sent him” (xiii. 16) ; and applies the idea of “mission” alike to Jesus (cf. Heb. iii. 1, “Jesus, the apostle ... of our profession”) and to his disciples, generally, as represented by the Twelve (xvii. 18, with 3, 6 ff.) ”
