And he went up from thence unto Bethel: and as he was going up from the way, there came forth little children, out of the city, and mocked him, and said unto him, Go up, thou bald head; go up, thou bald head. And he turned back, and looked on them , and cursed them in the name of the Lord. And there came forth two she bears out of the wood, and tare forty and two children of them.
2 Kings 2:23 and 24
I imagine a lot of people will say, "but these children were twelve or older." The Bible says "little children" and they were held accountable. As far as I can tell, the age of accountability idea is nowhere in the Bible, but has taken hold of peoples' minds. We won't even talk about the children who died in the flood.
Maybe there is something evil about anyone who mocked Elisha?
