Genesis 49:13 - The Popular Commentary by Paul E. Kretzmann

Zebulun shall dwell at the haven of the sea; and he shall be for an haven of ships; and his border shall be unto Zidon. The country later inhabited by the tribe of Zebulun fronted on two seas, on the Sea of Galilee in the east and on the Mediterranean in the west. Its northwestern boundary was to extend to Phenicia. Although the actual physical boundaries of Zebulun afterward did not include all this country, its influence extended to both seas and to Zidon by means of its commerce.
