Ezekiel 47:8

And go down into the desert— That is to say, along the plain towards the lake, where Sodom formerly stood, called the Dead or Salt Sea. Almost all the writers who describe this sea or lake, observe, that nothing can live in it. The text tells us, that these living and salubrious streams, by mixing with the salt and brackish waters of the sea, shall render them wholesome, and fit for use; mystically implying the healing virtue of God's grace in curing the vices of corrupt man.
