Philo Judaeus De Vita Contemplativa 68

[68] And the women also share in this feast, the greater part of whom, though old, are virgins in respect of their purity (not indeed through necessity, as some of the priestesses among the Greeks are, who have been compelled to preserve their chastity more than they would have done of their own accord), but out of an admiration for and love of wisdom, with which they are desirous to pass their lives, on account of which they are indifferent to the pleasures of the body, desiring not a mortal but an immortal offspring, which the soul that is attached to God is alone able to produce by itself and from itself, the Father having sown in it rays of light appreciable only by the intellect, by means of which it will be able to perceive the doctrines of wisdom.
