{He cometh into a house} (erchetai eis oikon). Historical
present again and no article with noun. He comes home from the
mountain, probably the house of Simon as in  1:29 . Mark passes
by the Sermon on the Mount given by Matthew and Luke on the
mountain (plateau on the mountain in Luke). We have to allow a
reasonable interval for Mark's narrative. Mark's Gospel is full
of action and does not undertake to tell all that Jesus did and
said.
