"They don't agree with what I have decreed. / They shake their heads and have not kept their necks under my yoke, as they are duty bound to do" (lines 337-339).
"I swear to you on oath---unless you find the one whose hands really buried him, / unless you bring him here before my eyes, / then death for you will never be enough" (lines 355-358).
"But I find your voice so irritating--- / don't you realize that" (lines 369-370)?
"Do I have your permission to speak now, / or do I just turn around and go away" (lines 367-368)?
Creon soon grows completely furious that his own people have disobeyed his commands. He cannot believe that someone would betray him like that. Due to hubris, he does not come to the understanding that each side could be right. Instead, he immediately proclaims that he is right, and no one else could possibly ever be right.
Creon tells the messenger that if he does not bring whoever buried Polyneices to him in front of his eyes, that the messenger will be dead and his death will still not be enough for Creon. This shows how overwhelmed Creon is with hubris that even death upon someone does not satisfy him.
After Creon threatens to kill the messenger that delivered this awful news, the messenger tries to run away and get out of there as quickly as possible by asking the king if he is allowed to leave and go away. Creon responds with a rhetorical question about how irritating his voice is to him.
