Acts 17:5, 13

But many of the Jews were motivated by bitter jealousy and formed a large mob out of the troublemakers, unsavory characters, and street gangs to incite a riot. They set out to attack Jason’s house, for he had welcomed the apostles into his home. The mob was after Paul and Silas and sought to take them by force and bring them out to the people.

When the news reached the Jews in Thessalonica that Paul was now in Berea, preaching the word of God, the troublemakers went there too and they agitated and stirred up the crowds against him.
