Shabtai Horowitz was a rabbi and talmudist, probably born in Ostroh, Volhynia.
Background
He was the son of the kabbalist Isaiah Horowitz, and at an early age married the daughter of the wealthy and scholarly Moses Charif of Lublin. With his father he seems to have gone to Prague, where he occupied a position as preacher. From Prague he went as rabbi to Fürth, whence he was called to Frankfurt am Main about 1632, and finally to Vienna about 1650.
Career
There he died on April 12, 1660. He also wrote an ethical testament (Ẓawwa"ah, Frankfort-on-the-Oder, nd, often reprinted). lieutenant contains, besides some very charitable teachings, exhortations to strictness in ritual practise and in kabbalistic studies.
Shabbethai further wrote some prayers (included in his father"s prayer-book), especially a selichah for the 20th of Sivan.
