וּגְב֣וּל יָ֔ם וְהָיָ֥ה לָכֶ֛ם הַיָּ֥ם הַגָּד֖וֹל וּגְב֑וּל זֶֽה־יִהְיֶ֥ה לָכֶ֖ם גְּב֥וּל יָֽם׃
Adapun batas barat, Laut Besar beserta wilayahnya akan menjadi batasmu; inilah yang akan menjadi batas baratmu.
Tosefta Challah (Lieberman)
The areas considered to be within the Land of Israel are those sloping down from the Mountains of Amanus inward, whereas regions beyond the Mountains of Amanus are outside of the Land of Israel. For islands in the Mediterranean Sea, an imaginary line is drawn from the Mountains of Amanus to the Brook of Egypt. Islands within this line are considered part of the Land of Israel, whereas islands outside of this boundary are considered outside the Land. According to R. Judah, all islands opposite the Land of Israel are considered part of it.
