There has been a great deal of discussion about the origin of the Philo’s interpretive method and whether he understood Hebrew or not. That obviously most likely was not the case. In Hellenistic Judaism, the Septuagint was the text that Philo used; it was also regarded as inspired as the Hebrew original. Some of the methods of interpretation that were practiced in the synagogue are also found in his commentaries. Identified even more strongly, however, are the exegetical principles of Greek philosophy.
