Answer:
But when he comes, I'll be a wicked man if I do not act on all the god reveals
Step-by-step explanation:
Based on what is known of the play, Oedipus is a stubborn man who refused to do the wishes of the oracle so the line that would best portray irony is the line that he says he'll be a wicked man if he does not act on what the god reveals.
Eventually, according to his fate, King Oedipus refuses to do the wishes of the oracle.
