Most of the 150 islands in the Med were promised to the Jews

From the Babylonian Talmud: Gittin 8a

What do we reckon as Eretz Israel (Land of Israel) and what do we reckon as foreign parts? From the top (whatever slopes down) of the Mountains of Ammanon inwards is 'Eretz Israel', and from the top of the Mountains of Ammanon outwards is 'foreign parts'. [For determining the status of] the islands in the sea, we imagine a line drawn from the Mountains of Ammanon to the Brook of Egypt. All within the line belongs to Eretz Israel and all outside the line to foreign parts. R. Judah, however, holds that all islands fronting the coast of Eretz Israel (Land of Israel) are reckoned as Eretz Israel, according to the verse of Scripture, And for the western border, ye shall have the Great Sea for a border; this shall be your west border (Numbers 34:6). [To determine the status of] the islands on the border line, we imagine a line drawn [due west] from Kapluria (undefined place immediately north of the Mountains of Ammanon) to the Ocean (the Atlantic) and another from the Brook of Egypt to the Ocean. All within these lines belong to Eretz Israel and all outside to foreign parts. And R. Judah? — He will rejoin that for the inclusion of the islands no special indication is required (And the words 'and for the border' include the more distant islands.).
