Though his statement of the civil and religious law is of great interest to the student of Halakic development, Philo's work presents greater correspondence, on the whole, with the Haggadah, which in a primitive way draws philosophical and ethical lessons from the Bible narrative. It is a free interpretation of the Scriptures, the expression of the individual moralist; it loves to point a moral and adorn a tale, and in many cases it is in agreement with the Hellenistic school. To take a few typical examples: An early interpretation explains the story of the Brazen Serpent, as Philo does,[302] to mean that as long as Israel are looking upward to the Father in Heaven they will live, but when they cease to do so they will die. Another, like him again, finds the motive of the command to bore the ear of the slave who will not leave his master at the seventh year of redemption, in the principle that men are God's servants, and should not voluntarily throw away their precious freedom. So, too, the Haggadah agrees in numerous points with Philo's stories about the patriarchs.[303] If one were to go through the Midrashic interpretations of the Five Books of Moses, he would find in nearly every section interpretations reminiscent of Philo. In some cases, however, there are striking contrasts in the two commentaries. Thus the Midrash[304] tells that the four rivers of Eden symbolize the four great nations of the old world; to Philo, they represent the four cardinal virtues established by Greek philosophers. The Palestinian commentators were prone to see an historical where Philo saw a philosophical image.
