Joh_6:30-31.
Οὖν
] What doest thou, therefore, as a sign? for they knew well enough that by
ὃν

ἐκεῖνος
He meant Himself, and that, too, as Messiah. Hence also the emphatic
σύ
, thou, on thy part. The question itself does not imply that it is asked by those who had not seen the miraculous feeding the day before (Grotius), or by prominent Jews in the synagogue (Kuinoel, Klee). Moreover, this demand for a sign after the miracle of the feeding must not be regarded as contradictory and unhistorical (Kern, B. Bauer, Weisse), nor as a proof of the non-Johannine origin (Schweizer), or non-miraculous procedure (Schenkel), in the account of the feeding. For the questioners, in their
ἀναίσθησις
(Chrysostom), indicate at once (Joh_6:31), that having been miraculously fed with earthly food, they, in their desire for miracles, require something higher to warrant their putting the required faith in Him, and expect a sign from heaven, heavenly bread, such as God had given by Moses. Thus they explain their own question, which would be strange only if Joh_6:31did not immediately follow. Their eagerness for Messianic miraculous attestation (Joh_6:14-15) had grown during the night. This also against De Wette, who, with Weisse, concludes that this discourse was not originally connected with the miraculous feeding; see, on the contrary, Brückner.

.] a free quotation of Psa_78:24; comp. Psa_105:40, Exo_16:4, where the subject of
ἔδωκεν
is God, but by the medium of Moses, this being taken for granted as known (Joh_6:32). The Jews regarded the dispensing of the manna as the greatest miracle (see Lampe). As they now regarded Moses as in general a type of Christ (Schoettgen, Hor. II. p. 475), they also hoped in particular, “Redemtor prior descendere fecit pro iis manna; sic et redemtor posterior descendere faciet manna.” Midrash Coheleth, f. 86. 4.
