Philo: On the Birth of Abel

XXXI. (102) But it is most entirely in accordance with nature "to sacrifice the males of every creature that openeth the womb, to God."

For as nature has given to women the womb, as the part most excellently adapted for the generation of animals, so also for the production of things she has placed a power in the soul, by means of which the mind conceives and is in travail, and brings forth many things. (103) But of the ideas which are brought forth by the mind, some are male and some female, as in the case of animals. Now the female offspring of the soul are wickedness and passion, by which we are made effeminate in every one of our pursuits; but a healthy state of the passions and virtue is male, by which we are excited and invigorated. Now of these, whatever belongs to the fellowship of men must be attributed to God, and everything that relates to the similarity to women must be imputed to one's self, on which account the command was delivered, "Of everything which openeth the womb the males belong to the Lord."
