Ezekiel 47:8-11
47:8 He said to me, “These waters go out toward the eastern region and flow down into the Arabah; when they enter the Dead Sea, where the sea is stagnant, the waters become fresh.
47:9 Every living creature which swarms where the river flows will live; there will be many fish, for these waters flow there. It will become fresh and everything will live where the river flows.
47:10 Fishermen will stand beside it; from Engedi to En-eglaim they will spread nets. They will catch many kinds of fish, like the fish of the Great Sea.
47:11 But its swamps and its marshes will not become fresh; they will remain salty.
