2 Kings 2:18-22 English Standard Version (ESV)

¹⁸ And they came back to him while he was staying at Jericho, and he said to them, “Did I not say to you, ‘Do not go’?”

¹⁹ Now the men of the city said to Elisha, “Behold, the situation of this city is pleasant, as my lord sees, but the water is bad, and the land is unfruitful.” ²⁰ He said, “Bring me a new bowl, and put salt in it.” So they brought it to him. ²¹ Then he went to the spring of water and threw salt in it and said, “Thus says the Lord, I have healed this water; from now on neither death nor miscarriage shall come from it.” ²² So the water has been healed to this day, according to the word that Elisha spoke.
