Ezekiel 47:9 (KJV)

Now when I had returned, behold, at the bank of the river were very many trees on the one side and on the other.

Then said he unto me, These waters issue out toward the east country, and go down into the desert, and go into the sea: which being brought forth into the sea, the waters shall be healed.

And it shall come to pass, that every thing that liveth, which moveth, whithersoever the rivers shall come, shall live: and there shall be a very great multitude of fish, because these waters shall come thither: for they shall be healed; and every thing shall live whither the river cometh.

And it shall come to pass, that the fishers shall stand upon it from En–gedi even unto En–eglaim; they shall be a place to spread forth nets; their fish shall be according to their kinds, as the fish of the great sea, exceeding many.

But the miry places thereof and the marishes thereof shall not be healed; they shall be given to salt.
