Sea of Galilee

In the time of Christ, the sea of Galilee was plied by little more than small fishing craft.

Isaiah 9:1

See 'Galilee of the Nations?' by William Finck or the article here on CIpedia concerning Capernaum

Isaiah 9:1 Nevertheless the dimness shall not be such as was in her vexation, when at the first he lightly afflicted the land of Zebulun and the land of Naphtali, and afterward did more grievously afflict her by the way of the sea, beyond Jordan, in Galilee of the nations.

How could Zebulun and Naphtali be afflicted by “... way of the sea beyond Jordan, in Galilee of the Nations”? That truly does not describe the sea of Galilee at all, and there is no discussion in the Old Testament describing any shipping traffic by Zebulun or Naphtali in that small sea. Even in the time of Christ, the sea of Galilee was plied by little more than small fishing craft. So what else may this statement mean?

It is evident that this in reference to Europe and Asia Minor, which was trafficked to by the Israelites in Tyre and Sidon and whom were the recipients of the Gospel message following the Passion of the Christ.
