Ke'zayit
Kezayit, k'zayit, or kezayis () is a Talmudic unit of volume approximately equal to the size of an average Talmudic-Era Israeli 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 (the volume of a Talmudic-Era chicken egg, literally meaning “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 of food that, when eaten, is halachically considered "eating." This h ... [...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 dimension (mathematics), 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 International System of Units, SI system, the base unit (measurement), base unit for measuring length is the metre.

Olive
The olive, botanical name ''Olea europaea'' ("European olive"), is a species of Subtropics, subtropical evergreen tree in the Family (biology), family Oleaceae. Originating in Anatolia, Asia Minor, it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern Cultivar, cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. The olive is the type species for its genus, ''Olea'', and lends its name to the Oleaceae plant family, which includes species such as Syringa vulgaris, lilac, jasmine, forsythia, and Fraxinus, ash. The olive fruit is classed botanically as a drupe, similar to the cherry or peach. The term oil—now used to describe any Viscosity, viscous Hydrophobe, water-insoluble liquid—was virtually synonymous with olive oil, the Vegetable oil, liquid fat made from olives. The olive has deep historical, economic, and cultural significance in the Mediterranean; Georges Duhamel (author), George ...

Halacha
''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'' or '' Mishneh Torah''. ''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" (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, widespread observance of the laws of the Torah is first in evidence beginning in the second century BCE, and some say that the first evidence was even earlier. In the Jewish diaspora, ''halakha'' served many Jewish comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milk And Meat
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. 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 Canaanite religious 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 interpreted as saying that a Levantine ritual to ensure agricu ...

Bracha Ahrona
Birkat Hamazon ( "The Blessing of the Food"), known in English as the Grace After Meals ( "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 understood as a mitzvah (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 (') and food that does not possess the form or appearance of bread ('), in which case a blessing that summarizes the first three blessings (') 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 typically read individually after ordinary meals. The blessing can be found in almost all siddurs and is often printed in a variety of arti ...

Ritual Purification
Ritual purification is a ritual prescribed by a religion through which a person is considered to be freed 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 Ancient Near Eastern religion, 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 t ...

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 Orthodox Jewish contemporary life, based on halacha. 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. Unit conversion Archaeological While documentation on each unit's relation to another's is plentiful, there is much debate, both within Judaism and in Jewish studies, academia ...
