What news does the messenger bring Oedipus?

The messenger arrives in Thebes with two pieces of news: that Polybus is dead and that Laius, Oedipus's father, has also passed away. However, the messenger reveals another crucial fact: Oedipus is not Polybus's biological child. He was found as a baby on Mount Cithaeron with pierced ankles and given to the king and queen of Corinth to raise.
