Ezekiel 47:7 (KJV)

Afterward he measured a thousand; and it was a river that I could not pass over: for the waters were risen, waters to swim in, a river that could not be passed over.

And he said unto me, Son of man, hast thou seen this? Then he brought me, and caused me to return to the brink of the river.

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.
