Mark 3:19

He cometh into a house (ercetai ei oikon). Historical present again and no article with noun. He comes home from the mountain, probably the house of Simon as in John 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.
