Philo Judaeus De Josepho 125

But since we have proposed to ourselves to give not only an explanation of the literal account given to us, but also of its more figurative meaning, we must say what is necessary to be said concerning that also. Perhaps now some persons of rash and inconsiderate dispositions will laugh; nevertheless, I will speak without concealing anything. And I will say that the statesman is at all times an interpreter of dreams, not classing him by this statement among the charlatans and vain chatterers, and men who put forth sophistical pretences by way of making money, or among those who profess the explanation of visions which have appeared to persons in their sleep in the hope of acquiring gain; but I mean that the statesman is accustomed to interpret accurately the great, and common, and universal general dreams, not only of sleeping but also of waking persons.
