JACOB BEN REUBEN
JACOB BEN REUBEN (12th century), Karaite biblical exegete, probably a native of Constantinople. He traveled to a number of countries to spread Karaism and at the same time tried to collect commentaries, mainly in Arabic, written by his Karaite predecessors. His biblical commentary Sefer ha-Osher is essentially a collection of excerpts from earlier Karaite authors, hence the frequent glosses in Greek and Arabic; some of these writings are otherwise unknown. His knowledge of the *Khazars and Slavs, whom he mentions, probably derives from the writings of his predecessors. Jacob mainly avails himself of the tenth-century Karaite exegete Japheth b. Ali, simply reproducing passages from his Arabic commentary. The polemics against *Saadiah Gaon and Muslim scholars are also taken from the writings of the Karaite *Salmon (Solomon) b. Jeroham. Of the works by Rabbanite authors, Jacob used those of Jonah ibn *Janāḥ and *Dunash ibn Labrat. Only his commentary on the Later Prophets (excepting Isaiah) and Hagiographa (excepting Psalms) titled Mivḥar Yesharim has appeared in print (Eupatoria, 1836) together with Sefer ha-Mivḥar by *Aaron b. Joseph (the Elder).

Encyclopedia.com 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, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com 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 Encyclopedia.com 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.
