2 Kings 2:21

and Elisha went out to the spring, cast the salt into it, and said, “This is what the LORD says: ‘I have healed this water. No longer will it cause death or unfruitfulness. ’”

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.
