M. Tullius Cicero Pro L. Murena 56

[56] And as these are weighty considerations, O judges, so is this the most serious matter of all, that he has men for accusers who, instead of proceeding to accuse him on account of their private enmity against him, have become his personal enemies, being carried away by their zeal for their accusation. For, to say nothing of Servius Sulpicius, who, I am aware, is influenced not by any wrong done by Lucius Murena, but only by the party spirit engendered by the contest for honour, his father's friend, Cnaeus Postumius, is his accuser, an old neighbour and intimate friend of his own, as he says himself; who has mentioned many reasons for his intimacy with him, while he has not been able to mention one for any enmity towards him. Servius Sulpicius accuses him, the companion of his son,—he, by whose genius all the friends of his father ought to be only the more defended. Marcus Cato accuses him, who, though he has never been in any matter whatever at variance with Murena, yet was born in this city under such circumstances that his power and genius ought to be a protection to many who were even entire strangers to him, and ought to be the ruin of hardly any personal enemy.
