Mark here (vv.  17-20 ) gives six keen questions of Jesus
while  Mt 16:8-11  gives as four that really include the six of
Mark running some together. The questions reveal the
disappointment of Jesus at the intellectual dulness of his
pupils. The questions concern the intellect (
oeite, from

ous, suniete, comprehend), the heart in a {hardened state}
(pep(9372)(936d)en(886e), perfect passive predicate participle as in  Mr
6:52 , which see), the eyes, the ears, the memory of both the
feeding of the five thousand and the four thousand here sharply
distinguished even to the two kinds of baskets (kophinous,
sphurid(936e)). The disciples did recall the number of baskets left
over in each instance, twelve and seven. Jesus "administers a
sharp rebuke for their preoccupation with mere temporalities, as
if there were nothing higher to be thought of _than bread_"
(Bruce). "For the time the Twelve are way-side hearers, with
hearts like a beaten path, into which the higher truths cannot
sink so as to germinate" (Bruce).
