The Lost Tribe of Zebulun is modern Greece.
The seal date in 1908 marks a treaty of union between Greece and Cyprus, so Cyprus is in this group as well. Greek is an official language of Cyprus.
Jacob's prophecy over Zebulun is that he will be a haven for ships.
13Zebulun will live at the shore of the seas; and he will be a haven for ships; and his border will extend as far as Sidon.
Greece is a nation of islands, a haven for ships. Shipping remains a major industry for Greece.
