"He was my friend, faithful and just to me: But Brutus says he was ambitious; and Brutus is an honourable man" (3.2.64). In this, Antony is feeding Caesar's credit in the public eye while indirectly discrediting Brutus by stating that, though honourable, Brutus did not respect his opinion of Caesar.
"Bear with me; My heart is in the coffin there with Caesar, And I must pause till it come back to me" (3.2.64). Antony is trying to make the citizens pity him, and make them feel like they can relate to him in their mourning of Caesar.
"I thrice presented him a kingly crown, Which he did thrice refuse: was this ambition?" (3.2.64). This is a fact that cannot be argued, although the reason for Caesar's action at that time was not the same as Antony implies. The reader knows that Caesar refused the crown as his own form of pathos, but the citizens saw it as an act of humility and a sign that he would be a kind ruler.
