John 6:9

ὃ ἔχει … ὀψάρια. The Synoptic account speaks of these provisions as already belonging to the disciples. κριθίνους, the cheapest kind of bread; see Ezekiel 13:19, and the extraordinary profusion of illustrations in Wetstein, among which occurs one from the Talmud: “Jochanan dixit, hordeum factum est pulchrum. Dixerunt ei: nuncia equis et asinis”; and from Livy, “Cohortibus, quae signa amiserant, hordeum dari jussit”. καὶ δύο ὀψάρια, in Matthew 14:17, ἰχθύας, see also John 21:10. ὀψάριον is whatever is eaten with bread as seasoning or “kitchen,” hence, pre-eminently, fish. So Athenaeus, cited by Wetstein. In Numbers 11:22 we have τὸ ὄψος τῆς θαλάσσης. ἀλλὰ ταῦτα τί ἐστιν εἰς τοσούτους; exhibiting the helplessness of the disciples and inadequacy of the means, as the background on which the greatness of the miracle may be seen.
