The name Ecclesiasticus, or “ecclesiastical book,” likely refers to the book’s extensive use in church liturgy. The book is also known as Sirach, a transliteration of its Greek name. See Alexander Di Lella, “Wisdom of Ben Sira,” Anchor Bible Dictionary (Garden City, NY: 1992), vol. 6, p. 931. See also Yigael Yadin, Masada, trans.
