religion. The title page of the first edition states that the work is "compiled from both Torahs, Written and Oral, handed down from Sinai". The work has had a profound influence on Jewish life - notably, on the early Hasidic movement, including the Baal Shem Tov; Shneur Zalman of Liadi was described as a "Shelah Yid", and Shelah clearly echoes in his work, Tanya. The work was first published in 1648 by his son, Shabbethai Horowitz, and has been often reprinted, especially in an abbreviated form. (See also שני לוחות הברית article in the Hebrew Wikipedia). Horowitz also wrote the Sha'ar ha-Shamayim siddur (prayer book) which had an influence on the later Ashkenazi nusach. Tefillat HaShlah - The Shelah's Prayer Rabbi Horowitz wrote that the eve of the first day of the month of Sivan is the most auspicious time to pray for the physical and spiritual welfare of one's children and grandchildren, since Sivan was the month that the Torah was given to the Jewish people. He composed a special prayer to be said on this day, known as the Tefillat HaShlah "the Shelah's Prayer". In modern times, the custom of saying this prayer on the appointed day has become very popular among Orthodox parents. Burial place He is buried in HaRambam compound / complex in Tiberias / Tveria.
