I will speak justly before you, Athena’s great tribunal,— since I am a prophet, I cannot lie. I have never yet, on my oracular throne, said anything about a man or woman or city that Zeus, the father of the Olympians, did not command me to say.
 Learn how strong this plea of justice is; and I tell you to obey the will of my father; for an oath is not more powerful than Zeus. The oath taken by the judges (489) may pronounce Orestes guilty as to the fact; but as his deed was done at the command of Zeus, whose representative is his son, Zeus therefore assumes all moral responsibility.
