"Believe me for mine honour, and have respect to mine honour, that you may believe: censure me in your wisdom... that you may the better judge" (act 3.scene 1. pg. 61). Brutus is explaining that he has always been for the people and that they can trust him.
"This is my answer: Not that I loved Caesar less, but I love Rome more" (act 3.scene 1.pg. 61). Brutus is telling them that he loved the safety of Rome more than Caesar and with him in power things would be bad for Rome.
"Had you rather Caesar were living and die all salves, than that Caesar were dead, to live all free men?" (Act 3.scene 1. pg.61). Brutus is saying would you rather be enslaved under Caesar's rule or live as a free man now that he is dead.
