After speaking of the books of the Wisdom of Solomon and Ecclesiasticus, which were sent at the same time, the Preface continues:
As, then, the Church reads Judith, Tobit, and the books of Maccabees, but does not admit them among the canonical Scriptures, so let it read these two volumes for the edification of the people, not to give authority to doctrines of the Church. If any one is better pleased with the edition of the Seventy, there it is, long since corrected by me. For it is not our aim in producing the new to destroy the old. And yet if our friend reads carefully, he will find that our version is the more intelligible, for it has not turned sour by being poured three times over into different vessels, but has been drawn straight from the press, and stored in a clean jar, and has thus preserved its own flavour.Jerome, Preface to Proverbs, Ecclesiastes, and the Song of Songs.
