Siddur with the commentary of R. Yaakov Emden, Part II - Shaarei Shamayim (prayers for festivals and more), Ashkenazi rite. Altona: [Printed in the home of the author R. Yaakov Rabbi of Emden - the Yaavetz], [1745-1747]. First edition.
Part II of the siddur with the commentaries of R. Yaakov Emden, according to revealed and kabbalistic approaches, based on the teaching of the Arizal. The first edition of this siddur is renowned for its great precision. R. Yaakov Emden expended great effort in establishing the exact text of the siddur, in the vocalization and accuracy of the words. This siddur was reprinted in many editions and was named by later printers "the Beit Yaakov siddur". In the siddur's later editions (Lviv and Warsaw), modifications and errors affected the text of the prayers, and all that remains of R. Yaakov Emden's corrections are his comments, integrated in his commentary printed in the margins. R. Yaakov Emden's siddur became widely accepted in the Chassidic world, and its second edition was printed in Korets in 1818, at the initiative and with the approbation of great Chassidic leaders: the rabbi of Apta and R. Mordechai of Chernobyl. The latter describes in his approbation the rarity of the first edition - the teachings of the Yaavetz are so cherished that "the siddurim have already become worn out, and there is not one to be found in the whole city". The Korets edition included only parts I and II, and in 1835, the third part was printed in Berditchev at the initiative and with the approbation of R. Mordechai of Chernobyl and R. Yisrael of Ruzhin (who praised the siddur in his approbation: "It was established and originates from golden foundations, in order to indicate the correct path with pure intellect on the topic of prayer"). The Imrei Yosef of Spinka wrote in the name of the sons of the Divrei Chaim of Sanz, who heard from their father who had a tradition that the Baal Shem Tov once told R. Efraim, brother of the Yaavetz: "Your brother the Yaavetz was connected to the Upper spheres all day" (approbation of R. Moshe Halberstam to the Eshkol edition of the siddur, Jerusalem 1993). Tzror HaChaim (by R. Ch. Liebersohn, Biłgoraj 1913, p. 22), quotes in the name of the Baal Shem Tov: "Chacham Tzvi had five sons, whom the Baal Shem Tov attested all merited Divine Inspiration, yet he offered especially effusive praise on one of them, without disclosing which one, but his friends confirmed that he was referring to the Yaavetz". The Yeshuot Moshe of Vizhnitz writes in his approbation to that same edition: "…This siddur did not depart from the tables of our teachers and ancestors, who utilized it constantly, especially while leading the Seder on Passover night". Rebbe Menachem Mendel of Lubavitch quoted corrections and practices from this siddur several times in his discourses, and once remarked "R. Yaakov Emden exercised ultimate precision in every way, to the point of being meticulous even regarding the letters etc." (BeTzel HaChochma, p. 265).
