From there Elisha went up to Bethel. As he was walking along the road, some youths came out of the town and jeered at him. Then two bears came out of the woods and mauled forty-two of the youths. And he went on to Mount Carmel and from there returned to Samaria. The Psalmist delights in the violent death of the babies.
