If ever you disturb our streets again,
Your lives shall pay the forfeit of the peace.

– William Shakespeare

Romeo and Juliet, Act 1, Scene 1. Prince Escalus, the voice of authority in Verona, threatens the feuding Capulins and Montagues that anyone found fighting again in the city will be sentenced to death. This is an example of dramatic irony, because the audience has already been told that the feud leads to the deaths of the young Romeo and Juliet.
