Philo Judaeus De Posteritate Caini 135

[135] on which account Moses, in strict accordance with the principles of natural philosophy, represents Leah as hated. ¹ For those whom the charms of pleasures, which are with Rachel, that is to say, with the outward sense, cannot be endured by Leah, who is situated out of the reach of the passions; on which account they repudiate and detest her. But as far as she herself is concerned, her alienation from the creature produces her a close connection with God, from whom she receives the seeds of wisdom, and conceives, and travails, and brings forth virtuous ideas, worthy of the father who begot them. If therefore, you, O my soul, imitating Leah, reject mortal things, you will of necessity turn to the incorruptible God, who will shed over you all the fountains of his good.
