Midrash for Ezekiel 48:2

Variantly: "The L-rd alone will lead him": The L-rd is destined to cause you to inherit from one end of the world to the other, as it is written (Ezekiel 48:2-4) "Next to Dan's border, from the eastern side to the western side — Asher, one portion. Next to Asher's border, from the eastern side to the western side — Naftali, one (portion)." What is the intent of "Yehudah, one (portion)," "Asher, one (portion)," "Dan, one (portion)"? That Israel is destined to take from east to west until the length of twenty-five thousand kanim, the extent of seventy-five mil.
