Halakha, also transliterated as halacha, halakhah, and halocho, is the collective body of Jewish religious laws that are derived from the Written and Oral Torah. Halakha is based on biblical commandments (mitzvot), subsequent Talmudic and rabbinic laws, and the customs and traditions which were compiled in the many books such as the Shulchan Aruch. Halakha is often translated as "Jewish law", although a more literal translation might be "the way to behave" or "the way of walking". The word is derived from the root which means "to behave". Halakha not only guides religious practices and beliefs; it also guides numerous aspects of day-to-day life.
The Mishnah or the Mishna is the first written collection of the Jewish oral traditions that are known as the Oral Torah. It is also the first work of rabbinic literature, with the oldest surviving material dating to the 6th to 7th centuries BCE.
The Talmud is, after the Hebrew Bible, the central text of Rabbinic Judaism and the primary source of Jewish religious law (halakha) and Jewish theology. Until the advent of modernity, in nearly all Jewish communities, the Talmud was the centerpiece of Jewish cultural life and was foundational to "all Jewish thought and aspirations", serving also as "the guide for the daily life" of Jews.
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.
A yeshiva is a traditional Jewish educational institution focused on the study of Rabbinic literature, primarily the Talmud and halacha, while Torah and Jewish philosophy are studied in parallel. The studying is usually done through daily shiurim as well as in study pairs called chavrusas. Chavrusa-style learning is one of the unique features of the yeshiva.
Torah study is the study of the Torah, Hebrew Bible, Talmud, responsa, rabbinic literature, and similar works, all of which are Judaism's religious texts. According to Rabbinic Judaism, the study is done for the purpose of the mitzvah ("commandment") of Torah study itself.
The Shulchan Aruch, sometimes dubbed in English as the Code of Jewish Law, is the most widely consulted of the various legal codes in Judaism. It was authored in Safed, Ottoman Syria by Joseph Karo in 1563 and published in Venice two years later. Together with its commentaries, it is the most widely accepted compilation of halakha or Jewish law ever written.
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 beth midrash, also beis medrash or beit midrash, is a hall dedicated for Torah study, often translated as a "study hall". It is distinct from a synagogue, although the two are often coextensive. In Yiddish the beth midrash may be referred to as a zal, i.e. "hall". Beis midrash can also refer to a yeshiva gedolah, the undergraduate-level program in Orthodox, for boys over 12th grade.
A Torah database is a collection of classic Jewish texts in electronic form, the kinds of texts which, especially in Israel, are often called "The Traditional Jewish Bookshelf" ; the texts are in their original languages. These databases contain either keyed-in digital texts or a collection of page-images from printed editions. Given the nature of traditional Jewish Torah study, which involves extensive citation and cross-referencing among hundreds of texts written over the course of thousands of years, many Torah databases also make extensive use of hypertext links.
According to Rabbinic Judaism, the Oral Torah or Oral Law are statutes and legal interpretations that were not recorded in the Five Books of Moses, the Written Torah, and which are regarded by Orthodox Jews as prescriptive and given at the same time. This holistic Jewish code of conduct encompasses a wide swathe of rituals, worship practices, God–man and interpersonal relationships, from dietary laws to Sabbath and festival observance to marital relations, agricultural practices, and civil claims and damages.
Jacob ben Meir, best known as Rabbeinu Tam, was one of the most renowned Ashkenazi Jewish rabbis and leading French Tosafists, a leading halakhic authority in his generation, and a grandson of Rashi. Known as "Rabbeinu", he acquired the Hebrew suffix "Tam" meaning straightforward; it was originally used in the Book of Genesis to describe his biblical namesake, Jacob.
In Jewish law and history, Acharonim are the leading rabbis and poskim living from roughly the 16th century to the present, and more specifically since the writing of the Shulchan Aruch in 1563 CE.
Rishonim were the leading rabbis and poskim who lived approximately during the 11th to 15th centuries, in the era before the writing of the Shulchan Aruch and following the Geonim. Rabbinic scholars subsequent to the Shulchan Aruch are generally known as acharonim.
Aggadah is the non-legalistic exegesis which appears in the classical rabbinic literature of Judaism, particularly the Talmud and Midrash. In general, Aggadah is a compendium of rabbinic texts that incorporates folklore, historical anecdotes, moral exhortations, and practical advice in various spheres, from business to medicine.
Abraham ben David, also known by the abbreviation RABaDRavad or RABaD III, was a Provençal rabbi, an important commentator on the Talmud, Sefer Halachot of Rabbi Yitzhak Alfasi and Mishne Torah of Maimonides, and is regarded as a father of Kabbalah and one of the key links in the chain of Jewish mystics.
Shabbat is the first tractate of Seder Moed of the Mishnah and of the Talmud. The tractate deals with the laws and practices regarding observing the Jewish Sabbath. The tractate focuses primarily on the categories and types of activities prohibited on the Sabbath according to interpretations of many verses in the Torah, notably Exodus 20:9–10 and Deut. 5:13–14.
Reuvein Margolies, was an Israeli author, Talmudic scholar and head of the Rambam library.
Sifrei Kodesh, commonly referred to as sefarim, or in its singular form, sefer, are books of Jewish religious literature and are viewed by religious Jews as sacred. These are generally works of Torah literature, i.e. Tanakh and all works that expound on it, including the Mishnah, Midrash, Talmud, and all works of Musar, Hasidism, Kabbalah, or machshavah. Historically, sifrei kodesh were generally written in Hebrew with some in Judeo-Aramaic or Arabic, although in recent years, thousands of titles in other languages, most notably English, were published. An alternative spelling for 'sefarim' is seforim.
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.
