39 Categories Of Activity Prohibited On Shabbat
The 39 ''Melakhot'' (, '' lamed-tet avot melakhah'', "39 categories of work") are thirty-nine categories of activity which Jewish law identifies as prohibited by biblical law on Shabbat. These activities are also prohibited on the Jewish holidays listed in the Torah ("Yom Tov"), but there are significant exceptions that permit carrying and preparing food under specific circumstances on holidays (except Yom Kippur). In addition to the 39 melakhot, certain other activities are forbidden on Shabbat due to rabbinic law. It is of note that the (strict) observance of Shabbat is often seen as a benchmark for orthodoxy and indeed has legal bearing on the way a Jew is seen by an Orthodox religious court regarding their affiliation to Judaism. The commandment The commandment to keep Shabbat as a day of rest is repeated many times in the Hebrew Bible. Its importance is also stressed in Exodus 31:12–17: Meaning of "work" Though ''melakha'' is usually translated as "work" in English, th ...

Hebrew Numerals
The system of Hebrew numerals is a quasi-decimal alphabetic numeral system using the letters of the Hebrew alphabet. The system was adapted from that of the Greek numerals sometime between 200 and 78 BCE, the latter being the date of the earliest archeological evidence. The current numeral system is also known as the ''Hebrew alphabetic numerals'' to contrast with earlier systems of writing numerals used in classical antiquity. These systems were inherited from usage in the Aramaic and Phoenician scripts, attested from in the Samaria Ostraca. The Greek system was adopted in Hellenistic Judaism and had been in use in Greece since about the 5th century BCE. In this system, there is no notation for zero, and the numeric values for individual letters are added together. Each unit (1, 2, ..., 9) is assigned a separate letter, each tens (10, 20, ..., 90) a separate letter, and the first four hundreds (100, 200, 300, 400) a separate letter. The later hundreds (500, 600, 700, 8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Showbread
Showbread (), in the King James Version shewbread, in a Biblical or Jewish context, refers to the cakes or loaves of bread which were always present, on a specially-dedicated table, in the Temple in Jerusalem as an offering to God. An alternative, and more appropriate, translation would be ''presence bread'',''Jewish Encyclopedia''. since the Bible requires that the bread be constantly in the presence of God (). Biblical references Within the Torah, the showbread is mentioned exclusively by the Priestly Code and Holiness Code, but certain sections of the Bible, including the Books of Chronicles, Books of Samuel, and Books of Kings, also describe aspects of them. In the Holiness Code, the showbread is described as twelve cakes baked from fine flour, arranged in two rows on a table; each cake was to contain "two tenth parts of an ephah" of flour (; approximately 5 pounds or 2 kg). The biblical regulations specify that cups of frankincense were to be placed upon the rows of cake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tannaim
''Tannaim'' ( Amoraic Hebrew: תנאים "repeaters", "teachers", singular ''tanna'' , borrowed from Aramaic) were the rabbinic sages whose views are recorded in the Mishnah, from approximately 10–220 CE. The period of the Tannaim, also referred to as the Mishnaic period, lasted about 210 years. It came after the period of the Zugot "Pairs" and was immediately followed by the period of the Amoraim "Interpreters". The root ''tanna'' () is the Aramaic equivalent of the Hebrew root ''shanah'' (), which also is the root word of ''Mishnah''. The verb ''shanah'' means "to repeat hat one was taught and is used to mean "to learn". The Mishnaic period is commonly divided into five periods according to generations. There are approximately 120 known Tannaim. The Tannaim lived in several areas of the Land of Israel. The spiritual center of Judaism at that time was Jerusalem, but after the destruction of the city and the Second Temple, Yohanan ben Zakkai and his students founded a n ...

Hydroponics
Hydroponics is a type of horticulture and a subset of #Passive sub-irrigation, hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral Plant nutrition, nutrient Solution (chemistry), solutions in an artificial environment. Terrestrial plant, Terrestrial or aquatic plants may grow freely with their roots exposed to the nutritious liquid or the roots may be mechanically supported by an inert medium such as perlite, gravel, or Hydroponics#Substrates (growing support materials), other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect rhizosphere biology and physiological balance of the nutrient solution when secondary metabolites are produced in plants. Genetically modified plant, Transgenic plants grown hydroponically allow the release of Pharming (genetics)#In plants, pharmaceutical proteins as part of the root exudate into the hydroponic medium.

Plough
A plough or ( US) plow (both pronounced ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an ''aratrum''. Celtic peoples first came to use wheeled ploughs in the Roman era. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting. Ploughing and cultivating soil evens the content of the upper layer of soil, where most plant feeder roots grow. Ploughs were initially powered by humans, but th ...

Mishna
The Mishnah or the Mishna (; , from the verb ''šānā'', "to study and review", also "secondary") is the first written collection of the Jewish oral traditions that are known as the Oral Torah. Having been collected in the 3rd century CE, it is the first work of rabbinic literature, written primarily in Mishnaic Hebrew but also partly in Jewish Palestinian Aramaic. The oldest surviving physical fragments of it are from the 6th to 7th centuries. The Mishnah was redacted by Judah ha-Nasi probably in Beit Shearim or Sepphoris between the ending of the second century CE and the beginning of the third century. Heinrich Graetz, dissenting, places the Mishnah's compilation in 189 CE (see: H. Graetz, ''History of the Jews'', vol. 6, Philadelphia 1898, p105), and which date follows that penned by Rabbi Abraham ben David in his "Sefer HaKabbalah le-Ravad", or what was then ''anno'' 500 of the Seleucid era. in a time when the persecution of Jews and the passage of time raised the po ...

Angels In Judaism
In Judaism, angels (, plural: ''mal’āḵīm'') are supernatural beings that appear throughout the Tanakh (Hebrew Bible), Rabbinic literature, Jewish apocrypha, Christian pseudepigrapha, Jewish philosophy, Jewish mysticism, and traditional Jewish liturgy as agents of the God of Israel. They are categorized in different hierarchies. Their essence is often associated with fire. The Talmud describes their very essence as fire. Etymology Hebrew ''mal’ākh'' is the standard word for "messenger", both human and divine, in the Hebrew Bible; it is also related to the words for "angel" in Arabic (''malāk'' ), Aramaic and Ethiopic. It is rarely used for human messengers in Modern Hebrew as the latter is usually denoted by the term ''shaliyakh'' (). The noun derives from the verbal consonantal root ''l-’-k'' (), meaning specifically "to send with a message" and with time was substituted with more applicable ''sh-l-h''.

Rabbinical Literature
Rabbinic literature, in its broadest sense, is the entire corpus of works authored by rabbis throughout Jewish history. The term typically refers to literature from the Talmudic era (70–640 CE), as opposed to medieval and modern rabbinic writings. It aligns with the Hebrew term ''Sifrut Chazal'' (), which translates to “literature f oursages” 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'' (commentaries and commentators) almost always refer to later, post-Talmudic writers of rabbinic glosses on Biblical and Talmudic texts. Mishnaic literature The Midr'she halakha, Mishnah, and Tosefta (compiled from materials pre-dating the year 200 CE) are the earliest extant ...

Chaff
Chaff (; ) is dry, scale-like plant material such as the protective seed casings of cereal grains, the scale-like parts of flowers, or finely chopped straw. Chaff cannot be digested by humans, but it may be fed to livestock, ploughed into soil, or burned. Etymology "Chaff" comes from Middle English , from Old English , related to Old High German ', "husk". Grain chaff In grasses (including cereals such as rice, barley, oats, and wheat), the ripe seed is surrounded by thin, dry, scaly bracts (called glumes, lemmas, and paleas), forming a dry husk (or hull) around the grain. Once it is removed, it is often referred to as chaff. In wild cereals and in the primitive domesticated einkorn,Potts, D. T.
