Ezekiel 47:11

“But its miry places and its marshes will not be healed. They will be given up to salt.”

At first sight this seems to be a sign of the failure of the river. But in fact the people would not have rejoiced at the idea of losing valuable salt resources, and this is rather evidence of the discrimination and continual provision of God. Salt is good (Mark 9:50; Luke 14:34). So the salt reserves will be preserved. In the new earth will be everything a man can need. Fish and salt together would provide man with abundant food.
