What message does Creon bring back to Oedipus from the oracle?

The message that Creon brings back to Oedipus from the oracle is to seek revenge on the killer of Laius. This directive sets the foundation for the unfolding tragedy in "Oedipus Rex." The oracle conveys that the plague afflicting Thebes is due to the unresolved murder of its former king, Laius, and that only by finding and punishing the murderer can Thebes be saved. This highlights Oedipus's role as a determined and vigilant leader, as he is eager to protect his city and his people. Moreover, the insistence on revenge reflects the themes of fate, justice, and the consequences of one’s actions that permeate the play, revealing how Oedipus's pursuit of truth ultimately leads to his tragic downfall.
