Tosefta sobre Números 34:6

What is considered "the Land [of Israel]" and what is considered "outside the Land [of Israel]" (Y. Shev. VI.1.22)? From the slopes of Taurus Amanus inwards is the "Land of Israel," from Taurus Amanus to the outside is "outside the Land." About the islands in the sea, one looks at them as if a string were drawn from Taurus Amanus to the rivers of Egypt: from the string to the inside is the "Land of Israel," from the string to the outside is "outside the Land." Rabbi Yehudah said, all that lies before the Land of Israel is like the Land of Israel since it is said (Num. 34:6): “The Eastern border shall be for you the Great Sea as border.” It is as if a string were drawn from Cephalaria to the Ocean, inside the string is the "Land of Israel," and outside is "outside the Land."
