History of the Peloponnesian War

You should do most uprightly to stand out of both our ways; and if not that, then to take our parts against the Corcyraeans (for between the Corinthians and you there are articles of peace, but with the Corcyraeans you never had so much as a truce) and not to constitute a new law of receiving one another's rebels.

For neither did we give our votes against you when the Samians revolted, though the rest of Peloponnesus was divided in opinion, but plainly alleged that it was reason that everyone should have liberty to proceed against their own revolting confederates.

And if you shall once receive and aid the doers of wrong, it will be seen that they will come over as fast from you to us; and you shall set up a law not so much against us as against yourselves.
