Komentaryo sa Mga Bilang 34:6: Rashi, Rashbam, Rabbeinu Bahya & Siftei Chakhamim

ים וגבול These words (apparently unconnected with what follows) mean: AND THE WESTERN BOUNDARY, what forms that?

(1) FOR THE WESTERN [LIT.: SEA] BOUNDARY. In other words, "And the western boundary, what is it? You shall have the Great Sea as the western boundar." (2) AND THE BORDER [UG'VUL]. Our Sages explained: to include the nesim in the sea, i.e., the islands of the sea (Esth. 10:1).

הים הגדול, “the Mediterranean,” known in the author’s time as “the Spanish Sea.” וגבול¸”and the western boundary.” The sea itself is the boundary. (Ibn Ezra).

והיה לכם הים הגדול THE GREAT SEA SHALL BE UNTO YOU for the boundary.

וגבול AND THE BOUNDARY — the נסין which are in the sea also belong to the boundary; they are what are called isles in O. F. (Gittin 8a).
