Tavnit HaBayit. Words of mussar by Rabbi Mordechai Klemens of Zamość. Frankfurt on the Oder. [1747]. First edition. [4], 56 leaves. 20 cm. Many approbations at the beginning and end of the book, along with the approbation of Rabbi Yisrael Halevi of Zamość that is not found in most copies. This omission is not coincidental: Rabbi Yisrael Halevi of Zamość authored the “Nezed HaDima” [Dyhernfurth, 1773] that it included polemic ideas and he taught Moses Mendelssohn. Refer to: G. Scholem, HaPulmus al HaChassidut U’Manhigeha B’Sefer Nezed HaDima’, Tzion, 20, 1955, p. 73-81; Ch. Lieberman, Keitzad Chokrim Chassidut B’Yisrael, from Ohel Rochel, 1, New York, 1980. P. 12-49. Rare. New binding. Aging stains. Fine-very fine condition.
