At first people married their own sisters, but they noticed that they were beating their wives excessively, so they determined: We will not marry our own sisters but each will marry the sister of another, so that everyone will say: "If I beat my wife I shall be called to account by her brother and he will take my property away." If they had continued as they began they would have killed their wives, for they said: "If she dies what difference does it make, whose business is it?"2
