It's not the oath that makes us believe the man, but the man the oath - Aeschylus

That child of earth too, the inhabitant of Cilician caves, hostile, monstrous, with a hundred heads — I saw and pitied him as he was violently overcome, Typhon furious for war, who stood against all the gods, hissing terror with dreadful jaws, and who flashed a fierce gleam from his eyes, intent on the violent ruin of tyranny. Zeus’ unsleeping bolt came to him, however, the lightning which descends in a blast of flame; it hit him out of his lofty boastings; he was struck to the very soul of his being, blazing like a coal, and his strength blasted from him in thunder.

ATHENA: There are two sides to this dispute. I've heard only one half the argument. (...) So you two parties, summon your witnesses, set out your proofs, with sworn evidence to back your stories. Once I've picked the finest men in Athens, I'll return. They'll rule fairly in this case, bound by a sworn oath to act with justice.

Nothing that strikes a note of brutal conquest. Only peace blessings, rising up from the earth and the heaving sea, and down the vaulting sky let the wind-gods breathe a wash of sunlight streaming through the land, and the yield of soil and grazing cattle flood our city's life with power and never flag with time. Make the seed of men live on, the more they worship you the more they thrive. I love them as a gardener loves his plants, these upright men, this breed fought free of grief. All that is yours to give. And I, in the trials of war where fighters burn for fame, will never endure the overthrow of Athens all will praise her, victor city, pride of man. The furies assemble, dancing around Athena, who becomes their leader.
