Sirach
Sirach, also called Ecclesiasticus or the Wisdom of Ben Sira, is the longest wisdom book of the biblical tradition: a Jerusalem sage's collected teaching on friendship, speech, money, family, worship, and above all the fear of the Lord. Its summit is chapter 24, where Wisdom praises herself and settles in Israel, identified with the Torah; its climax is the great praise of Israel's ancestors. Written in Hebrew around 180 BC and translated into Greek by the author's grandson, it is deuterocanonical Scripture for Catholics and Orthodox, while Protestants class it among the Apocrypha—long used for teaching, as its Latin name suggests.
