Judah Ha-Parsi


JUDAH HA-PARSI ("the Persian"), medieval scholar. No details are known about his personality or period. He is first mentioned by Abraham *Ibn Ezra (12th century), who states that Judah wrote a work attempting to prove that the ancient Israelites calculated the calendar according to the solar year, like the other peoples of antiquity. S. *Pinsker, and later H. *Graetz and I.H. *Weiss, identified him with the eighth-century sectarian leader *Yudghān, of Persian origin, but this identification seems highly doubtful. Some scholars consider Judah to have been a Karaite. These include S.I. Luzki, who ascribes to Judah a commentary on the Pentateuch. There is, however, no mention of Judah in Karaite literature.

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:

  • 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.
