Genesis 10:5

The isles of the Gentiles. Javan’s descendants, the various Greek tribes mentioned in the preceding verse — the people of Greece and islands adjacent to it, of Sicily, Sardinia, Spain, and Cyprus — went forth to settle the islands and coastal regions of the Mediterranean. This verse indicates that the names given designate only main tribal groups. Apparently, further branching out had occurred by the time of Moses. When Genesis was written the populations of the central and western Mediterranean were subdivided into many different groups, all probably descended from Javan, the fourth son of Japheth.
