וְצִים֙ מִיַּ֣ד כִּתִּ֔ים וְעִנּ֥וּ אַשּׁ֖וּר וְעִנּוּ־עֵ֑בֶר וְגַם־ה֖וּא עֲדֵ֥י אֹבֵֽד׃
Des flottes, parties de la côte de Kitttm, subjugueront Assur, subjugueront Héber mais lui aussi est voué à la ruine."
Rashi on Numbers
צים מיד כתים SHIPS FROM THE LAND OF CHITTIM and the people of Chittim — these are the Romans — will pass over in big ships against Assyria.
Rashbam on Numbers
וצים, as in Isaiah 33,21 וצי אדיר, where not even a mighty vessel can keep afloat.
Tur HaArokh
וצים מיד כתים, “and Tzim from Kittim;” a reference to the Romans.”
