Lines 5-6 include a religious metaphor: the city is in desperate need of help from a godly and powerful figure like Oedipus.
Lines 7-15 display hubris or pride, with the heavy use of first person pronouns ("I"). This establishes authority and dominance. As well, calling everyone "children" marks superiority.
Line 16 follows up on the above theme when the priest praises Oedipus, calling him by his kingly title.
