At the end of act 1 scene iv, what does romeo tell benvolio, foreshadowing future action in the play?

The incidence of foreshadowing is something that is incredibly common in this excellent tragedy, as both Romeo and Juliet at various points in the play predict tragedy is in the offing for them both. In this case, having decided to go to the Capulet ball that night, Romeo tells Benvolio that he will go, but he fears that events will be set in motion at this ball that will result in the loss of his life.
