Philo: On the Posterity of Cain and His Exile

XXI. (73) What, then, follows a man who lives not in accordance with the will of God but the death of the soul? And this is named Methuselah, the interpretation of which name is, "the sending out of death," on which account he is the son of Mehel, who has quilted his own life, to which death is sent, that is to say the death of the soul, which is nothing else than a conversion of it by irrational passion. (74) This passion, therefore, when it has conceived, brings forth incurable diseases and infirmities with great pains, by which it is thrown down and convulsed, and humbled and tortured.

For each of the diseases oppresses it, bringing upon it an unspeakable burden, such that no one is able even to raise his head beneath it. And this is named Lamech; the interpretation of which name is, "humiliation;" so that Lamech is properly represented as the son of Methuselah, being the passion of the death of the soul, humble, yielding, an infirmity which is the offspring of irrational desire.
