Acts 16:19-21

19But when her owners saw that their hope of profit was gone, they seized Paul and Silas and dragged them before the authorities in the market place [where trials were held],

20and when they had brought them before the chief magistrates, they said, “These men, who are Jews, are throwing our city into confusion and causing trouble.

21They are publicly teaching customs which are unlawful for us, as Romans, to accept or observe.”
