Most classical commentators interpret Noach’s blessing to his son Yefet in terms of territory:
Beraishit 9:27
“Yaft Elokim LeYefet…” (God “Yaft” to Yefet)
RaShI: Onkelos interprets “broaden/expand”.
Rabbeinu Bachaye: He blessed Yefet with a broadening of boarders, and the Aramaic translation of (Devarim 12:20) “When He will Broaden”—“Arei Yafti”. And still today, the descendants of Yefet comprise multiple nations and their lands are many and broad.
