2 Kings 2:20-22

Elisha said, “Bring me a new bowl and put salt in it.” So they brought it to him. Then he went out to the spring and threw the salt in it. He said, “This is what the LORD says: ‘I have healed this water. From now on it won’t cause death, and it won’t keep the land from growing crops.’ ” So the water has been healed to this day just as Elisha had said.
