Ezekiel 47:8-9

8And he said unto me, These waters issue out toward the east district, and go down into the plain, and go into the sea; when they are brought forth into the sea, the waters [thereof] shall be healed.

9And it shall come to pass that every living thing which moveth, whithersoever the double river shall come, shall live. And there shall be a very great multitude of fish; for these waters shall come thither, and [the waters of the sea] shall be healed; and everything shall live whither the river cometh.
