2 Kings 2:19-22

19The men of the city said to Elisha, “My lord can see that even though the city’s location is good, the water is bad and the land unfruitful.”

20He replied, “Bring me a new bowl and put salt in it.” After they had brought him one,

21Elisha went out to the spring, threw salt in it, and said, “This is what the Lord says: ‘I have healed this water. No longer will death or unfruitfulness result from it.’”

22Therefore, the water still remains healthy today according to the word that Elisha spoke.
