Several Hellenistic-Jewish texts demonstrate reliance on the Septuagint (LXX) rather than the Hebrew Bible, indicating its widespread use within these Jewish communities centuries before the Christian era. Writings such as the Book of Wisdom, the works of Philo of Alexandria, and certain Dead Sea Scrolls fragments reflect linguistic and theological influences from the Greek translation, suggesting it was a well-established and authoritative text in the Hellenistic world. These sources show that the Septuagint was not uniquely Christian but played a significant role in Jewish thought and textual traditions before the emergence of Christianity.
