The author of this book was Jesus Ben Sira (in Hebrew, "Joshua Son of Sirach"), who was a noted teacher of the second century B.C. The contents of the book closely resemble those of the Old Testament book of Proverbs.  The first part of the book contains the author's sayings on moral behavior, wealth, women, and children. The middle part praises God for his work in nature and with the people of Israel. The last section praises the heroes of Israel's history, including Noah, Abraham, Moses, Aaron, and others. It concludes by honoring Simon the high priest, and giving thanks to God.
