cannot make clear, for example, the well-known tannaitic passage that lists the thirteen principles upon which the talmudiec interpretation of the Bible is based. Included in the Siddur in order to complete the daily minimum of study required of every Jew, they are on the lips of countless worshipers. Yet very few have learned precisely what these important principles are, because the old translation is too obscurely worded for the student to make out its meaning.
Designed for laymen, the footnotes are written in non-technical style and contain no abbreviations. To save space they include references only to original sources which do not bear long titles. Great authorities like Amram Gaon, Saadyah Gaon, Rashi, Maimonides and their works on the Siddur are mentioned only on rare occasions. The footnotes embody illuminating information derived from a wide range of commentaries and works of scholars like Abrahams, Baer, Berliner, Dembitz, Elbogen, Finkelstein, Friedlander, Ginzberg, Heidenheim, Idelsohn, Pool, and Yaavets. Each note begins with a Hebrew catchword, and is so worded that anyone can readily find the explanation he seeks.
The biblical references at the bottom of the English pages serve to indicate the central source of whatever has gone into the composition of the Siddur. The biblical phrases and expressions woven into the texture of the liturgical poems are indicated in the notes which, at the same time, contain biographical sketches of the authors.
It is hoped that a better and more widely disseminated understanding of our religious resources will result from this edition. It remains only to emphasize that such an inspiring book as the Siddur does not become the real possession of a person unless its contents are impressed upon his mind and influence his everyday life.
January, 1949.
