Ezekiel 47:17-18

So the boundary will extend from the [Mediterranean] Sea to Hazar-enan at the border of Damascus, and on the north, northward, is the border of Hamath. This is the north side. “The east side, from between Hauran, Damascus, Gilead, and the land of Israel, shall be the Jordan; from the north border to the eastern sea you shall measure. This is the east side.
