Genesis 10:5

5. By these were the isles of the Gentiles divided Rather, from these [Japhethites] have the [dwellers on the] islands of the [Gentile] nations divided themselves in their lands . “Islands,” in the Old Testament, means the isles, coasts, and peninsulas of the Mediterranean . The writer knew only of the “enlargement” of Japheth over the Mediterranean coasts and isles, but modern linguistic and monumental research shows that these ancient Hebrew names outline those vast pre-historic migrations of the Japhetic race from the great plateau of Iran eastward into Asia, westward and north-westward into Asia Minor and Europe, the traces of which may be found to-day from the Indian peninsulas to the Atlantic, and from the Mediterranean to the frozen ocean.

After his tongue… their families… nations The peoples called Turanian (a linguistic, rather than an ethnic, name) were on the ground at the dawn of tradition itself, and their origin is yet obscure; successive families of the Indo-European (Aryan) race swept eastward and westward, wave after wave, each to a great degree obliterating the traces of its predecessor, yet, as Rawlinson expresses it, leaving detached fragments of the superseded race in holes and corners, as the Turanian Laps and Fins are left in their remote peninsulas as the Keltic Welsh and Scotch are left in their highlands, mountains, and islands scattered patches of peoples who once thinly covered the continent.
