Ezekiel 47:17, 18

The boundary will extend from the sea to Hazar Enan, along the northern border of Damascus, with the border of Hamath to the north. This will be the northern boundary.

“On the east side the boundary will run between Hauran and Damascus, along the Jordan between Gilead and the land of Israel, to the Dead Sea and as far as Tamar. This will be the eastern boundary.
