{So that they could not so much as eat bread} (h(9373)te m(880a)dunasthai autous m(8864)e arton phagein). Note infinitive with
h(9373)te. Apparently Jesus and the disciples indoors with the
great crowd in the house and at the door as in  1:32  2:2  to
which Mark refers by "again." The jam was so great that they
could not rest, could not eat, and apparently Jesus could not
even teach. The crowd reassembled at once on Christ's return from
the mountain.
