7As I went back, I saw on the bank of the river avery many trees on the one side and on the other. 8And he said to me, “This water flows toward the eastern region and goes down into bthe Arabah, and enters the sea;
That is,  the Dead Sea
when the water flows into dthe sea, the water will become fresh.
Hebrew will be healed; also verses 9, 11

18“On the east side, the boundary shall run between Hauran and Damascus; along the Jordan between fGilead and the land of Israel; to gthe eastern sea and as far as Tamar.
Compare Syriac; Hebrew  to the eastern sea you shall measure
This shall be the east side.
