Zayit Stone
Kezayit, k'zayit, or kezayis () is a Talmudic unit of volume approximately equal to the size of an average olive. The word itself literally means "like an olive." The rabbis differ on the precise definition of the unit: * Rabbeinu Yitzchak (the Ri) defines it as one-half of a beytza (a beytza is the volume of an egg). * Maimonides specified that a 'grogeret' (dried fig) was one-third of a beytza, making this the maximum size for a kezayit, which is smaller. Rabbeinu Tam made the argument explicitly, though, using a slightly different calculation came out with a maximum definition of three-tenths. * According to some interpretations, including the Chazon Ish, the ''zayit'' is not related to other units by a fixed ratio, but rather should only be conceived of independently as the size of an average olive. Its uses in halacha include: * The minimum amount food that, when eaten, is halachically considered "eating." This has implications throughout the spectrum of halacha, including: ...

Talmud
The Talmud (; he, , Talmūḏ) is 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. The term ''Talmud'' normally refers to the collection of writings named specifically the Babylonian Talmud (), although there is also an earlier collection known as the Jerusalem Talmud (). It may also traditionally be called (), a Hebrew abbreviation of , or the "six orders" of the Mishnah. The Talmud has two components: the Mishnah (, 200 CE), a written compendium of the Oral Torah; and the Gemara (, 500 CE), an elucidation of the Mishnah and related Tannaitic writings that often ventures onto other subjects and expounds broadly on the Hebrew Bible. The term "Talmud" may refer to eith ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Of Volume
A unit of volume is a unit of measurement for measuring volume or capacity, the extent of an object or space in three dimensions. Units of capacity may be used to specify the volume of fluids or bulk goods, for example water, rice, sugar, grain or flour. Units According to the SI system, the base unit for measuring length is the metre. The SI unit of volume is thus the cubic metre, which is a derived unit, where: at nist.gov.

Olive
The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as ''Olea europaea'' 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. ''Olea europaea'' is the type species for the genus ''Olea''. The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree. Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maimonides
Musa ibn Maimon (1138–1204), commonly known as Maimonides (); la, Moses Maimonides and also referred to by the acronym Rambam ( he, רמב״ם), was a Sephardic Jewish philosopher who became one of the most prolific and influential Torah scholars of the Middle Ages. In his time, he was also a preeminent astronomer and physician, serving as the personal physician of Saladin. Born in Córdoba, Almoravid Empire (present-day Spain), on Passover eve, 1138 (or 1135), he worked as a rabbi, physician and philosopher in Morocco and Egypt. He died in Egypt on 12 December 1204, when his body was taken to the lower Galilee and buried in Tiberias. During his lifetime, most Jews greeted Maimonides' writings on Jewish law and ethics with acclaim and gratitude, even as far away as Iraq and Yemen. Yet, while Maimonides rose to become the revered head of the Jewish community in Egypt, his writings also had vociferous critics, particularly in Spain. Nonetheless, he was posthumously ackno ...

Halacha
''Halakha'' (; he, הֲלָכָה, ), also transliterated as ''halacha'', ''halakhah'', and ''halocho'' ( ), is the collective body of Jewish religious laws which is 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 of it might be "the way to behave" or "the way of walking". The word is derived from the root which means "to behave" (also "to go" or "to walk"). ''Halakha'' not only guides religious practices and beliefs, it also guides numerous aspects of day-to-day life. Historically, in the Jewish diaspora, ''halakha'' served many Jewish communities as an enforceable avenue of law – both civil and religious, since no differentiation of them exists in classical Judaism. Since the Jewish Enlightenment (''Hask ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milk And Meat
Mixtures of milk and meat ( he, בשר בחלב, basar bechalav, meat in milk) are 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. Explanations for the law The rabbis of the Talmud gave no reason for the prohibition,''Hullin'' 108a but later authorities, such as Maimonides, opined that the law was connected to a prohibition of idolatry in Judaism. Obadiah Sforno and Solomon Luntschitz, rabbinic commentators living in the late Middle Ages, both suggested that the law referred to a specific foreign anaanitereligious practice, in which young goats were cooked in their own mothers' milk, aiming to obtain supernatural assistance to increase the yield of their flocks. More recently, a theogonous text named ''the birth of the gracious gods'', found during the rediscovery of Ugarit, has been interpret ...

Bracha Ahrona
Birkat Hamazon ( he, בִּרְכַּת הַמָּזוׂן, The Blessing of the Food), known in English as the Grace After Meals ( yi, ; translit. ''bentschen'' or "to bless", Yinglish: Bentsching), is a set of Hebrew blessings that Jewish law prescribes following a meal that includes at least a kezayit (olive-sized) piece of bread. It is a understood as a Biblical Commandment based on Deuteronomy 8:10. Birkat Hamazon is recited after a meal containing bread or similar foods that is made from the five grains, with the exception of bread that comes as a dessert (''pas haba'ah b'kisanin'') and food that does not possess the form or appearance of bread (''torisa d'nahama''), in which case a blessing that summarizes the first three blessings (''birkat me'ein shalosh'') is recited instead. It is a matter of rabbinic dispute whether ''birkat hamazon'' must be said after eating certain other bread-like foods such as pizza. Except in teaching situations, ''Birkat hamazon'' is typi ...

Ritual Purification
Ritual purification is the ritual prescribed by a religion by which a person is considered to be free of ''uncleanliness'', especially prior to the worship of a deity, and ritual purity is a state of ritual cleanliness. Ritual purification may also apply to objects and places. Ritual uncleanliness is not identical with ordinary physical impurity, such as dirt stains; nevertheless, body fluids are generally considered ritually unclean. Most of these rituals existed long before the germ theory of disease, and figure prominently from the earliest known religious systems of the Ancient Near East. Some writers connect the rituals to taboos. Some have seen benefits of these practices as a point of health and preventing infections especially in areas where humans come in close contact with each other. While these practices came before the idea of the germ theory was public in areas that use daily cleaning, the destruction of infectious agents seems to be dramatic. Others have descri ...

Ancient Hebrew Units Of Measurement
Biblical and Talmudic units of measurement were used primarily by ancient Israelites and appear frequently within the Hebrew Bible as well as in later rabbinic writings, such as the Mishnah and Talmud. These units of measurement continue to be used in functions regulating Jewish contemporary life. The specificity of some of the units used and which are encompassed under these systems of measurement (whether in linear distance, weight or volume of capacity) have given rise, in some instances, to disputes, owing to the discontinuation of their Hebrew names and their replacement by other names in modern usage. Note: The listed measurements of this system range from the lowest to highest acceptable halakhic value, in terms of conversion to and from contemporary systems of measurement. Contemporary unit conversion While documentation on each unit's relation to another's is plentiful, there is much debate, both within Judaism and in academia, about the exact relationship between mea ...
