The final part of Ezekiel's prophecy describes a river that will flow from the altar in the Temple, and the waters of this river will heal the land.  The results will be that the Dead Sea will become fresh water, and the trees along the river will bring forth fruit all of the months of the year.  God will once again care for His people.  The life-giving water from God will bring fruitfulness to a barren land, and it will bring dead things back to life!
