Philo Judaeus De Migratione Abrahami 84

[84] And how was it possible for Moses to encounter such men as these unless he had prepared speech, the interpreter of his mind, namely Aaron? who now indeed is called his mouth; but in a subsequent passage we shall find that he is called a prophet, when also the mind, being under the influence of divine inspiration, is called God. "For," says God, "I give thee as a God to Pharaoh, and Aaron thy brother shall be thy prophet." ¹ O the harmonious and well-organised consequence! For that which interprets ^{2 3} the will of God is the prophetical race, being under the influence of divine possession and frenzy.
