Peraḥyah ben Nissim


PERAḤYAH BEN NISSIM (13th century), talmudist. No biographical details are known of him. In a document dated 1240 he is mentioned as being in Fostat, Egypt. In 1247 he wrote a commentary on the halakhot of Isaac *Alfasi and a manuscript of it in the tractate Shabbat, written in 1304, is preserved in the Bodleian Library.

Extracts from the work are cited in the novellae on Maimonides' Mishneh Torah, which are published at the beginning of the Ma'aseh Roke'ah of Mas'ud Roke'ah, and additional fragments were published by Assaf in Kirjath Sepher. Many of the quotations from Maimonides given by M.L. Sachs in his Ḥiddushei ha-Rambam la-Talmud (1963) were taken from this work. A section of the work on chapters five and six was published at the end of the Siyya'ta di-Shemayya (1970).


S. Assaf, in: Sinai, 16 (1940), 106; idem, in: ks, 23 (1946–47), 233–5; Z. Benedict, in: ks, 28 (1952/53), 211–3; Mann, Egypt, 1 (1920), 248 n. 1, 2 (1922), 297 no. 1.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
