2 Kings 2:18-22

18When they came back to him while he staying in Jericho, he said to them, “Didn’t I tell you not to go?”

19Then the men of the city said to Elisha, “Look now, the situation of this city is pleasant, as my lord sees, but the water is bad and the land barren.”

20He responded, “Bring me a new jar, and put salt in it.” So they brought it to him.

21Then he went out to the spring of water, threw salt in it and said, “Thus says Adonai, I have healed this water. No longer will there be from there death or barrenness.”

22So the waters were healed to this day, according to the word that Elisha spoke.
