2 Kings 2:23-24 (New International Version)
Elisha Is Jeered
23 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. “Go on up, you baldhead!” they said. “Go on up, you baldhead!” 24 He turned around, looked at them and called down a curse on them in the name of the LORD. Then two bears came out of the woods and mauled forty-two of the youths.
The moral: Don’t dis one of God’s prophets, or he’ll sick bears on you. Pretty straightforward really.
