Commentary on Wisdom of Jesus the Son of Sirach, Also Called Ecclesiasticus

The Wisdom of Jesus the Son of Sirach, also known as Ecclesiasticus, is the longest book of the deuterocanon, originally written in Hebrew and later translated into Greek. It was incorporated into the Septuagint in the second century BCE and played a significant role in shaping teachings that connect the Old and New Testaments. Frequently referenced by Jesus, the Apostles, and early Christians, it contains ideas that echo in the teachings of Jesus Christ, including the Sermon on the Mount.
