Trace out the elements of hope in the words of Oedipus Rex

I suppose that the murder in this section revolves around when Oedipus swears to solve the murder, both as part of his duty as king as well as for the good of the city: ‘So helping the dead king I help myself’ (141). All soon exit, save for the chorus. The chorus of children pray to the gods Apollo, Athene, Artemis and Phoebus in the Parode, compare the city of Thebes to a ship whose “timbers are rotten” (169), and beg for help lifting the curse.
