2 Kings 2:21

Then he went to the spring of water and threw salt in it and said , Thus says the Lord , I have healed this water ; from now on neither death nor miscarriage shall come from it .

Then he went out to the spring and threw the salt into it, saying, “This is what the Lord says: ‘I have healed this water. Never again will it cause death or make the land unproductive.`”

And he went forth unto the spring of the waters, and cast the salt in there, and said, Thus saith the Lord, I have healed these waters; there shall not be from thence any more death or barren land .
