The Wisdom of Sirach
His book is a collection of ethical and religious teaching, composed in Hebrew around 180 BC in Jerusalem. Because the author refers to the high priest Simon, son of Onias, in the past tense, and makes no mention of the upheavals that followed under the Seleucid king Antiochus IV Epiphanes, scholars place its composition between roughly 196 and 175 BC. Unlike the Book of Proverbs, which gathers sayings from many hands, the Wisdom of Sirach is presented as the work of a single author who signed his name to it.
The book treats wisdom as inseparable from the fear of the Lord and from faithfulness to the Law of Moses, joining practical counsel on conduct, speech, family, and society to its reverence for God. Its closing chapters, the Praise of the Fathers, celebrate the great ancestors of Israel from Enoch down to the high priest Simon, a survey of the righteous that resonates with the Church's own commemoration of the Forefathers.
