The wisdom of Jesus ben Sira (Sirach) is contained in the book commonly called Ecclesiasticus.
Ben Sira indeed in his list of worthies mentions Zerubbabel, Joshua and Nehemiah; but Zerubbabel and Joshua he must have known from the books of Haggai and Zechariah, and he may well have been acquainted with that document relating to Nehemiah which the Chronicler incorporated with his book.
Ben Sira's omission of the name of Ezra rather militates against the supposition that he had the Chronicler's book before him when he.
Of the large number of Apocryphal books existing in Syriac8 the majority have been translated from Greek, one or two (such as Bar Sira or Ecclesiasticus) from Hebrew, while some (like the Doctrine of Addai above referred to) are original Syriac documents.
Of books of this period which are known to have existed in Hebrew or Aramaic up to the time of Jerome (and even later) we now possess most of the original Hebrew text of Ben Sira (Ecclesiasticus) in a somewhat corrupt form, and fragments of an Aramaic text of a recension of theTestaments of theTwelve Patriarchs,both discovered within recent years.
