Philo Judaeus De Decalogo 167

[167] There are also many other commandments given, some to the young, admonishing them to receive gladly the admonitions of old age; others to the old, bidding them take care of the young; some to subjects, enjoining them to show obedience to their rulers; others to the rulers, commanding them to consult for the advantage of those who are under their authority; some to those who have received benefits, recommending them a requital of the favours which have been conferred on them; others to those who have set the example of beneficence, bidding them not to exact a strict restitution as if they were usurers; some to servants, encouraging them to show an affectionate service towards their masters, others to the masters recommending them to practise that gentleness and mildness towards their slaves, by which the inequality of their respective conditions is in some degree equalised.
