The major literary product of the contact of Judaism and Hellenistic culture is the Septuagint, as well as the Book of Wisdom, Sirach, apocrypha and pseudepigraphic apocalyptic literature (such as the Assumption of Moses, the Testaments of the Twelve Patriarchs, the Book of Baruch, the Greek Apocalypse of Baruch, etc.) dating to the period. Important sources are Philo of Alexandria and Flavius Josephus. Some scholars consider Paul of Tarsus to be a Hellenist as well, even though he himself claimed to be a Pharisee (Acts 23:6).
