2 Kings 2:18-22

18When they came back, Elisha was staying in Jericho. He said to them, “Didn’t I tell you, ‘Don’t go’?”

19The men of the city said to Elisha, “Look, the city has a good location, as our master can see. But the water is bad and the land doesn’t produce crops.”

20Elisha said, “Get me a new jar and put some salt in it.” So they got it.

21He went out to the spring and threw the salt in. Then he said, “This is what the Lord says, ‘I have purified this water. It will no longer cause death or fail to produce crops.”

22The water has been pure to this very day, just as Elisha prophesied.
