II Kings 2:19-25

Then 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.” And he said, “Bring me a new bowl, and put salt in it.” So they brought it to him. Then 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.’ ” So the water remains healed to this day, according to the word of Elisha which he spoke. Then he went up from there to Bethel; and as he was going up the road, some youths came from the city and mocked him, and said to him, “Go up, you baldhead! Go up, you baldhead!” So he turned around and looked at them, and pronounced a curse on them in the name of the LORD. And two female bears came out of the woods and mauled forty-two of the youths. Then he went from there to Mount Carmel, and from there he returned to Samaria.
