The Book of Sirach, also known as Ecclesiasticus, is a masterpiece of Jewish wisdom literature, serving as a bridge between the older wisdom of Proverbs and the later teachings of the rabbis. Written by a devout scribe in Jerusalem, it is a passionate defense of Israel's heritage in an age of encroaching Greek culture. Sirach teaches that the 'fear of the Lord' is the foundation of all wisdom, and that this wisdom is found fully and finally in the Law of Moses. The book is a treasure trove of practical advice on everything from friendship and family to finance and etiquette. It culminates in a majestic hymn to God's work in creation and a stirring roll call of Israel's heroes, celebrating God's faithfulness through history.
