Ezekiel 47:17-18

So the border line will go from the Mediterranean Sea east to the town of Hazar Enan, where the land belonging to Damascus and Hamath lies on the north side. This will be the north side of the land. “On the east side the border runs south from a point between Hauran and Damascus. It will go along the Jordan between Gilead and the land of Israel and will continue to the town of Tamar on the Dead Sea. This will be the east side of the land.
