Acts 19:32

‘Some therefore cried one thing, and some another, for the assembly was in confusion, and the majority did not know why they were come together.'

But while the silversmiths and their employees knew exactly why they were there, the larger proportion who had been gathered by the commotion had no idea. They had only come because they had been hustled into it, or because they felt that it was their responsibility to do so when a situation like this arose. Thus the assembly became confused, and the majority were still asking what it was all about.
