II Kings 2:14, 20-22, 24

Then he took the mantle of Elijah that had fallen from him, and struck the water, and said, “Where is the LORD God of Elijah?” And when he also had struck the water, it was divided this way and that; and Elisha crossed over.

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.

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.
