Philo Judaeus Quod Omnis Probus Liber Sit 104

[104] Shall we then say that he is the slave, or rather the master of his master, when he dares in this manner not only to accost him with such freedom, but even to impose injunctions on him who has purchased him, as if he would beat and insult him if he were to be stubborn and disobedient, and, if he introduced any one to assist him, as if he would destroy them all to a man? Therefore the writings which were delivered respecting this purchase must have been an utter absurdity and a mere joke, since they would be trampled upon by the more effectual power of the slave bought under them, being of less value than unwritten covenants, and being likely to be utterly destroyed by moths, or time, or mould and rust.
