Philo: On the Creation

LV. (155) Therefore, having laid down these to be boundaries as it were in the soul, God then, like a judge, began to consider to which side men would be most inclined by nature. And when he saw that the disposition of man had a tendency to wickedness, and was but little inclined to holiness or piety, by which qualities an immortal life is secured, he drove them forth as was very natural, and banished him from paradise; giving no hope of any subsequent restoration to his soul which had sinned in such a desperate and irremediable manner.

Since even the opportunity of deceit was blameable in no slight degree, which I must not pass over in this place. (156) It is said that the old poisonous and earthborn reptile, the serpent, uttered the voice of a man. And he on one occasion coming to the wife of the first created man, reproached her with her slowness and her excessive prudence, because she delayed and hesitated to gather the fruit which was completely beautiful to look at, and exceedingly sweet to enjoy, and was, moreover, most useful as being a means by which men might be able to distinguish between good an evil.

And she, without any inquiry, prompted by an unstable and rash mind, acquiesced in his advice, and ate of the fruit, and gave a portion of it to her husband. And this conduct suddenly changed both of them from innocence and simplicity of character to all kinds of wickedness; at which the Father of all was indignant. For their actions deserved his anger, inasmuch as they, passing by the tree of eternal life, the tree which might have endowed them with perfection of virtue, and by means of which they might have enjoyed a long and happy life, preferred a brief and mortal (I will not call it life, but) time full of unhappiness; and, accordingly, he appointed them such punishment as was befitting.
