Mark 5:21

And when Jesus had crossed over again in the boat unto the other side, a great multitude was gathered unto him; and he was by the sea.

The other side ... means the western shore of Galilee; and the scene would have been the sky-sea-land theater in which the pulpit was a boat, not far from the city of Capernaum. In a sense, Capernaum was the ordinary residence of Jesus. As Bickersteth noted:

Matthew (Matthew 4:13) tells us that he had left Nazareth, and was now dwelling at Capernaum, thus fulfilling the ancient prophecy with regard to Zebulun and Naphthalim (Luke 4:16-31). Matthew (Matthew 9:1) calls Capernaum his own city. Christ ennobled Bethlehem by his birth, Nazareth by his education, Jerusalem by his death, and Capernaum by making it his ordinary residence.[11]
