Kashrut is a set of dietary laws dealing with the foods that Jewish people are permitted to eat and how those foods must be prepared according to Jewish law. Food that may be consumed is deemed kosher, from the Ashkenazi pronunciation of the term that in Sephardi or Modern Hebrew is pronounced kashér, meaning "fit". Food that may not be consumed, however, is deemed treif, also spelled treyf. In case of objects the opposite of kosher is pasúl.
Rabbinic literature, in its broadest sense, is the entire spectrum of works authored by rabbis throughout Jewish history. The term typically refers to literature from the Talmudic era, as opposed to medieval and modern rabbinic writings. It aligns with the Hebrew term Sifrut Chazal, which translates to “literature [of our] sages” and generally pertains only to the sages (Chazal) from the Talmudic period. This more specific sense of "Rabbinic literature"—referring to the Talmud, Midrashim, and related writings, but hardly ever to later texts—is how the term is generally intended when used in contemporary academic writing. The terms mefareshim and parshanim almost always refer to later, post-Talmudic writers of rabbinic glosses on Biblical and Talmudic texts.
The Mishnah Berurah is a work of halakha by Rabbi Yisrael Meir Kagan. It is a commentary on Orach Chayim, the first section of the Shulchan Aruch which deals with laws of prayer, synagogue, Shabbat and holidays, summarizing the opinions of the Acharonim on that work.
The Mishneh Torah, also known as Sefer Yad ha-Hazaka, is a code of Rabbinic Jewish religious law (halakha) authored by Maimonides. The Mishneh Torah was compiled between 1170 and 1180 CE, while Maimonides was living in Egypt, and is regarded as Maimonides' magnum opus. Accordingly, later sources simply refer to the work as "Maimon", "Maimonides", or "RaMBaM", although Maimonides composed other works.
A hechsher or hekhsher is a rabbinical product certification, qualifying items that conform to the requirements of Jewish religious law.
A mashgiach or mashgicha is a Jew who supervises the kashrut status of a kosher establishment. Mashgichim may supervise any type of food service establishment, including slaughterhouses, food manufacturers, hotels, caterers, nursing homes, restaurants, butchers, groceries, or cooperatives. Mashgichim usually work as on-site supervisors and inspectors, representing a kosher certification agency or a local rabbi, who actually makes the policy decisions for what is or is not acceptably kosher. Sometimes certifying rabbis act as their own mashgichim; such is the case in many small communities.
Kosher foods are foods that conform to the Jewish dietary regulations of kashrut. The laws of kashrut apply to food derived from living creatures and kosher foods are restricted to certain types of mammals, birds and fish meeting specific criteria; the flesh of any animals that do not meet these criteria is forbidden by the dietary laws. Furthermore, kosher mammals and birds must be slaughtered according to a process known as shechita and their blood may never be consumed and must be removed from the meat by a process of salting and soaking in water for the meat to be permissible for use. All plant-based products, including fruits, vegetables, grains, herbs and spices, are intrinsically kosher, although certain produce grown in the Land of Israel is subjected to other requirements, such as tithing, before it may be consumed.
Negiah, literally "touch", is the concept in Jewish law (Halakha) that forbids or restricts sensual physical contact with a member of the opposite sex except for one's spouse, outside the niddah period, and certain close relatives to whom one is presumed not to have sexual attraction. A person who abides by this halakha is colloquially described as a shomer negiah.
Klaf or Qelaf is the designation given a particular piece of skin. The Talmudic definition includes both the form of the skin and the way it is processed, in particular, that it must be tanned. Since the innovative ruling of Rabbeinu Tam it is primarily used to refer to parchment or vellum. It is one of the materials upon which a sofer writes certain Jewish liturgical and ritual documents.
According to halacha, married Jewish women are expected to cover their hair when in the presence of men other than their husband or close family members. Such covering is common practice among Orthodox Jewish women.
Avodah Zarah is the name of a tractate of the Talmud, located in Nezikin, the fourth Order of the Talmud dealing with damages. The main topic of the tractate is laws pertaining to Jews living amongst Gentiles, including regulations about the interaction between Jews and "avodei ha kochavim", which literally interpreted is "Worshipers of the stars", but is most often translated as "idolaters", "pagans", or "heathen."
Bishul Yisrael is a Hebrew term for one of the laws of kashrut in Judaism. The rule prohibits eating certain foods if they are cooked exclusively by non-Jews. The term is the opposite of bishul akum, which the rule forbids. Akum (עכו"ם) is an acronym of Ovdey Kochavim U'Mazalot, literally "worshippers of stars and zodiac signs", but is actually a term for non-Jews).
From the founding of political Zionism in the 1890s, Haredi Jewish leaders voiced objections to its secular orientation, and before the establishment of the State of Israel, the vast majority of Haredi Jews were opposed to Zionism, like early Reform Judaism, but with distinct reasoning. This was chiefly due to the concern that secular nationalism would redefine the Jewish nation from a religious community based in their alliance to God for whom adherence to religious laws were "the essence of the nation's task, purpose, and right to exists," to an ethnic group like any other as well as the view that it was forbidden for the Jews to re-constitute Jewish rule in the Land of Israel before the arrival of the Messiah. Those rabbis who did support Jewish resettlement in Palestine in the late 19th century had no intention to conquer Palestine and declare its independence from the rule of the Ottoman Turks, and some preferred that only observant Jews be allowed to settle there.
Jewish heresy refers to those beliefs which contradict the traditional doctrines of Rabbinic Judaism, including theological beliefs and opinions about the practice of halakha. Jewish tradition contains a range of statements about heretics, including laws for how to deal with them in a communal context, and statements about the divine punishment they are expected to receive.
Star-K Kosher Certification, also known as the Vaad Hakashrut of Baltimore, is a kosher certification agency based in Baltimore, Maryland, under the administration of Rabbi Moshe Heinemann, with the involvement of many other rabbis. It is one of the largest Jewish dietary certification agencies in North America. It is trusted by many Orthodox Jews worldwide for dedication to preserving Kashrut. The organization supervises tens of thousands of commercial food products and food establishments around the world.
The mixture of meat and dairy is forbidden according to Jewish law. This dietary law, basic to kashrut, is based on two verses in the Book of Exodus, which forbid "boiling a (goat) kid in its mother's milk" and a third repetition of this prohibition in Deuteronomy.
In Jewish law, Pas Yisroel or Pat Yisrael products are grain-products that were cooked or baked with the participation of an observant Jew.
In Jewish law, a posek is a legal scholar who determines the application of halakha, the Jewish religious laws derived from the written and Oral Torah, in cases of Jewish law where previous authorities are inconclusive, or in those situations where no clear halakhic precedent exists.
