What examples does Antony give to disprove Brutus's claim that Caesar was ambitious? What phrase does Antony repeat?

He was my friend, faithful and just to me.

He hath brought many captives home to Rome
Whose ransoms did the general coffers fill.

I thrice presented him a kingly crown,
Which he did thrice refuse. Was this ambition?

Antony repeats the phrase....

Brutus is an honorable man.
