2 Kings 2:16-22

16Then they said to him, “Look now, there are fifty strong men with your servants. Please let them go and search for your master, lest perhaps the Spirit of the Lord has taken him up and cast him upon some mountain or into some valley.” And he said, “You shall not send anyone.”

17But when they urged him till he was ashamed, he said, “Send them!” Therefore they sent fifty men, and they searched for three days but did not find him.

18And when they came back to him, for he had stayed in Jericho, he said to them, “Did I not say to you, ‘Do not go’?”

19Then the men of the city said to Elisha, “Please notice, the situation of this city is pleasant, as my lord sees; but the water is bad, and the ground barren.”

20And he said, “Bring me a new bowl, and put salt in it.” So they brought it to him.

21Then he went out to the source of the water, and cast in the salt there, and said, “Thus says the Lord: ‘I have healed this water; from it there shall be no more death or barrenness.’ ”

22So the water remains healed to this day, according to the word of Elisha which he spoke.
