Acts 17:5, 13

But other Jews were jealous; so they rounded up some bad characters from the marketplace, formed a mob and started a riot in the city. They rushed to Jason’s house in search of Paul and Silas in order to bring them out to the crowd.

But when the Jews in Thessalonica learned that Paul was preaching the word of God at Berea, some of them went there too, agitating the crowds and stirring them up.
