In this small little scene, Oedipus is talking to the priest of Thebes and the priest is asking for change in Thebes, for there to be a new ruler and for that new ruler to be Oedipus. Oedipus knows what is going on in Thebes and is trying to fix it.
Oedipus, my king, please save our city, be our builder. Don't let us remember of the last rule.
My Brother-In-Law, Oedipus, Phoebus our lord tells us to drive out the pollution in our land. We must kill or exile the man who is responsible for the death of our King Laius.
In this scene Creon tells Oedipus to rid of the pollution that is in Thebes which is to find the murderer of the King Laius and rid of him of or exile him.
You Oedipus are the pollution in our city, you are the murderer of King Laius.
In this scene we find out who is the murderer of King Laius and we now understand why Tiresias does not want to speak when asked to.
Oedipus is infuriated with what has just happened and can't understand why Tiresias has said a thing like this.
Tiresias how dare you say that to me. You have never thought of anything but gaining and you say this to take my throne. Whoever you planned this with, with suffer with you.
The irony in Oedipus the Rex is that Tiresias asks Oedipus if he is good at solving riddels and Oedipus answers "of course." The irony is that by Oedipus trying to find out who killed King Laius, he just killed himself by digging to far and uncovering the truth with what actually happened.
If you, Oedipus, can detect a lie that I have said, then I am no true seer.
Tiresias knows he is not lying and he is so confident he is not that he tells Oedipus if he can find a lie, then you strip me of identity and call me a lier.
