The Wisdom of Ben Sira (Ecclesiasticus) contains the sayings of Ben Sira, arguably the last of Israel's wise men and its first scribe, whose world was defined and dominated by Greek ideas and ideals. This Hellenistic worldview challenged the adequacy of the religion passed down to Palestinian Jews of the second century B.C.E. by their ancestors. Ben Sira's training in both Judaic and Hellenistic literary traditions prepared him to meet this challenge. He vigorously opposed any compromise of Jewish values; and his teaching bolstered the faith and confidence of his people.

Through its elegant poetry and vehement exhortations, The Wisdom of Ben Sira exposes the ill effects of sinful behavior on one's health status, and spiritual and material well-being. Ben Sira's rigorous code of moral behavior was the measure of Jewish faithfulness in an era of ethical and religious bankruptcy.
