      Mr 4:1-34. PARABLE OF THE SOWER--REASON FOR TEACHING IN PARABLES--PARABLES OF THE SEED GROWING WE KNOW NOT HOW, AND OF THE MUSTARD SEED. ( = Mt 13:1-23, 31, 32; Lu 8:4-18).

      1. And he began again to teach by the seaside: and there was gathered unto him a great multitude--or, according to another well-supported reading, "a mighty" or "immense multitude."
      so that he entered into a ship--rather, "the ship," meaning the one mentioned in Mr 3:9. (See on Mt 12:15).
      and sat in the sea; and the whole multitude was by the sea on the land--crowded on the seashore to listen to Him. (See on Mt 13:1, 2.)
