. Its importance is also stressed in :

And the LORD spoke unto Moses, saying: 'Verily ye shall keep My sabbaths, for it is a sign between Me and you throughout your generations, that ye may know that I am the LORD who sanctify you. Ye shall keep the sabbath therefore, for it is holy unto you; every one that profaneth it shall surely be put to death; for whosoever doeth any work (melakha—מְלָאכָה) therein, that soul shall be cut off from among his people. Six days shall work be done; but on the seventh day is a sabbath of solemn rest, holy to the LORD; whosoever doeth any work in the sabbath day, he shall surely be put to death. Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. It is a sign between Me and the children of Israel for ever; for in six days the LORD made heaven and earth, and on the seventh day He ceased from work and rested.'

Meaning of "work"

Though melakha is usually translated as "work" in English, the term does not correspond to the English definition of the term, as explained below.

The Rabbis in ancient times had to explain exactly what the term meant, and what activity was prohibited to be done on the Sabbath. The Rabbis noted :
Heaven and earth, and all their components, were completed. With the seventh day, God finished all the work (melakha) that He had done. He ceased on the seventh day from all the work (melakha) that he had been doing. God blessed the seventh day, and he declared it to be holy, for it was on this day that God ceased from all the work (melakha) that he had been creating to function.


Specifically, the Rabbis noted the symmetry between Genesis 2:1–3 and Exodus 31:1–11—the same term melakha ("work") is used in both places, and that in Genesis 2:1–3 what God was "ceasing from" was "creation" or "creating".

The Rabbis noted further that the first part of provides detailed instructions for the construction of the Tabernacle

, quoted above. The Rabbis note that in the provisions relating to the Tabernacle the word melakha is also used. The word is usually translated as "workmanship", which has a strong element of "creation" or "creativity".

From these common words (in the Hebrew original) and the juxtaposition of subject matter the rabbis of the Mishna derive a meaning as to which activities are prohibited to be done on the Sabbath day.

is not pushed aside by the commandments to construct the Tabernacle. The classical rabbinical definition of what constitutes "work" or "activity" that must not be done, on pain of death (when there was a Sanhedrin

), is depicted by the thirty-nine categories of activity needed for the construction and use of the Tabernacle.

What are they?

The thirty-nine melakhot are not so much activities as categories of activity. For example, while "winnowing" usually refers exclusively to the separation of chaff

Plowing
Plough
The plough or plow is a tool used in farming for initial cultivation of soil in preparation for sowing seed or planting. It has been a basic instrument for most of recorded history, and represents one of the major advances in agriculture...

Hebrew:

Definition: Promotion of substrate in readiness for plant growth, be it soil, water for hydroponics, etc.

Included in this prohibition is any preparation or improvement of land for agricultural use. This includes dragging chair legs in soft soil thereby unintentionally making furrows. Pouring water on arable land that is not saturated. Making a hole in the soil would provide protection for a seed placed there from rain and runoff; even if no seed is ever placed there, the soil is now enhanced for the process of planting.

The Mishna (Shabbat 7:2) lists plowing after planting, although one must plow a field before planting. The Gemara asks why this order occurs and answers that the author of this Mishna was a Tanna

, where the ground is hard. Since the ground is so hard in Israel, it needed to be plowed both before planting and after planting. The Mishna lists plowing second, teaching that the second plowing (after planting) is [also] prohibited. (The plowing before the planting is also prohibited, if not by the Torah, certainly Rabbinically). The Rambam lists plowing first, and planting second.

Hebrew:

Definition: Initial gathering of earth-borne material in its original place.

E.g. After picking strawberries, forming a pile or collecting them into one's pockets, or a basket. Collecting rock salt or any mineral (from a mine or from the Earth) and making a pile of the produce. This can only occur in the place where the gathering should take place. So, a bowl of apples that falls in a house can be gathered as 1) they do not grow in that environment and 2) they have already undergone their initial gathering at the orchard.

This is a large topic of study. It refers to any productive extraction and includes juicing of fruits and vegetables and wringing (desirable fluids) out of cloths, as the juice or water inside the fruit is considered 'desirable' for these purposes, while the pulp of the fruit would be the 'undesirable.' As such, squeezing (S'chita) is forbidden unless certain rules are applied. The wringing of undesirable water out of cloths may come under the law of Melabain (Scouring/Laundering)

 (the Rema) holds that the definition according to the Jerusalem Talmud should be used. This is more inclusive and general than the Babylonian Talmud's definition and therefore more things fall under this category.

In the Talmudic sense usually refers exclusively to the separation of chaff

—i.e. to any separation of intermixed materials which renders edible that which was inedible.

It also refers to separating things that are desirable from indesirable ones. Example: If one has a handful of peanuts, in their paper-thin brown skins, and one blows on the mixture of peanuts and skins dispersing the unwanted skins from the peanuts, this would be an act of 'winnowing' according to both the Babylonian and Jerusalem Talmud.

According to the Jerusalem Talmud's definition, the use of the Venturi tube

 would come under this prohibition, while butane or propane propelled sprays, which are common in deodorants and air fresheners, etc. are permissible to operate as the dispersal force generated isn't from air, rather from the propellent within the can. According to the Babylonian Talmud's definition neither of the above spraying methods are involved in sorting undesirable from desirable and therefore not part of this heading. However, as mentioned the Rema rules that, unusually, we are to accept the Jerusalem Talmud's definition in this case.

is one solution to this problem.)

Dosh & Borer contrasted. This activity differs from Dosh (Threshing/Extraction) as here there is a mixture of types. Sorting a mixture via the removal of undesirable elements leaving a purified, refined component is the key process of Borer.

Dosh is the extraction of one desirable thing from within another which is not desired. "Dosh" does not entail sorting or purification, just extraction of the inner from the unwanted housing or outer component, such as squeezing a grape for its juice. The juice and the pulp have not undergone sorting, the juice has been extracted from the pulp.

For example, if there is a bowl of mixed peanuts & raisins and one desires the raisins and dislikes the peanuts: Removing (effectively sorting) the peanuts from the bowl, leaving a 'purified' pile of raisins free from unwanted peanuts, would be acts of Borer as the peanuts are removed. However, removing the desirable raisins from the peanuts does not purify the mixture, as one's left with undesirable peanuts (hence unrefined) not a refined component as before, and is thus permissible. Note that in this case there has not been any extraction of material from either the peanuts or raisins (Dosh), just the sorting of undesirable from desirable (Borer).

General Introduction:
After threshing, a mixed collection of waste matter remained on the threshing floor together with the grain kernels. Included in this combination would be small pebbles and similar debris.
These pebbles could not be separated by winnowing because they were too heavy to be carried by the wind. The pebbles and debris were therefore sorted and removed by hand. This process is the Melacha of Borer.

Any form of selecting from (or sorting of) an assorted mixture or combination can be borer. This includes removing undesired objects, or matter from a mixture or combination.


Borer with Mixed Foods:
Even though the classic form of borer as performed in the Mishkan involved the removal of pebbles and similar waste matter from the grain produce, Borer is by no means limited to the removal of “useless” matter from food. In fact, any selective removal from a mixture can, indeed, be Borer, even if the mixture contains an assortment of foods. The criteria are types and desire, not intrinsic value. Therefore, removing any food or item from a mix of different types of foods simply because he does not desire the item at that time is considered Borer.


The Three Conditions of Borer:
Sorting or selecting is permitted when three conditions are fulfilled simultaneously. It is absolutely imperative that all three conditions be present at the time of the Borer.
  1. B’yad (By hand): The selection must be done by hand and not a utensil that aids in the selection.
  2. Ochel Mitoch Psolet (Good from the bad): The desired objects must be selected from the undesired, and not the reverse.
  3. Miyad (Immediate use): The selection must be done immediately before the time of use and not for later use. There is no precise amount of time indicated by the concept of "immediate use" ("miyad"). The criteria used to define "immediate use" relate to the circumstances. For instance if a particular individual prepares food for a meal rather slowly, that individual may allow a more liberal amount of time in which to do so without having transgressed "borer."


Examples of Permissible and Prohibited Types of Borer:
  1. Peeling fruits: Peeling fruits is permissible with the understanding that the fruit will be eaten right away.
  2. Sorting silverware: Sorting silverware is permitted when the sorter intends to eat the Shabbat meal immediately. Alternatively, if the sorter intends to set up the meal for a later point, it is prohibited.
  3. Removing items from a mixture: If the desired item is being removed from the mix then this is permissible. If the non-desired item is being removed, the person removing is committing a serious transgression according to the laws of Shabbat.

Hebrew:

Definition: Reducing an earth-borne thing's size for a productive purpose.

"Tochain" (grinding) can arise in simply cutting into pieces fruits or vegetables for a salad. Very small pieces would involve "tochain," therefore cutting into slightly larger than usual pieces would be in order, thus avoiding cutting the pieces into their final, most usable, state.

All laws relating to the use of medicine
Medicine
Medicine is the science and art of healing. It encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness....

 on the shabbath are a Toldah, or sub-category, of this order, as most medicines require pulverization at some point and thus undergo tochain. The laws of medicine use on the sabbath are complex; they are based around the kind of illness the patient is suffering from and the type of medication or procedure that is required. Generally, the more severe the illness (from a halachic perspective) the further into the list the patient's situation is classed. As a patient is classed as more ill there are fewer restrictions and greater leniencies available for treating the illness on the Sabbath. The list of definitions, from least to most severe, is as follows: -
  1. מיחוש בעלמא / Maychush b'Alma / Minor Indisposition
  2. מקצת חולי / Miktzat Choli / Semi-illiness
  3. צער גדול / Tza'ar Godol / Severe Pain (Can in some cases be practically regarded as level 4)
  4. חולה כל גופו / Choleh Kol Gufo / Debilitating Illness
  5. סכנת אבר / Sakanat Aiver / Threat to a Limb or Organ (Can in some cases be practically regarded as level 6)
  6. ספק פיקוח נפש / Sofek Pikuach Nefesh / Possibly Life-Threatening (Practically treated as level 7)
  7. פיקוח נפש / Pikuach Nefesh / Certainly Life-Threatening


For most practical applications the use of medicines on the Sabbath, there are primarily two categories of non-life threatening (Pikuach Nefesh) illnesses & maladies. They are either Maychush b'Alma or Choleh Kol Gufo. In many or most practical applications for non-trained personnel, there are practically only three category levels (1, 4, & 7) as the line of distinction between them can often be difficult to ascertain for the untrained and it may prove dangerous to underestimate the condition.

Hebrew:

Definition: Sorting desirable from undesirable via a straining utensil.

This is essentially the same as the melochah of Borer, but performed with a utensil specifically designed for the purpose of sorting, such as a sieve, strainer, or the like. As such, Borer acts done with such a device, such as the netting of a tea bag, would be classed as an act of Merakaid (Sieving/Straining).

Kneading is not a very accurate translation of this activity. It may better be translated as 'amalgamation' or the like. The key principle of this creative activity is the combining of solid and liquid together to make a paste or dough-like substance.

There are four categories of substances produced: -
  1. Blilah Aveh (a thick, dense mixture)
  2. Blilah Racha (a thinner, pourable mixture)
  3. Davar Nozel (a pourable liquid with a similar viscosity to water)
  4. Chatichot Gedolot (large pieces mixed with a liquid)


Only a Blilah Aveh is biblically forbidded to make on the Sabbath while Blilah Racha mixtures are rabbinically forbidden to make without the use of a "shinui", such as the reversing the adding of the ingredients or mixing in criss-cross motions to differentiate the task, in which case they are permitted. As davar nozel & Chatichot Gedolot are not really mixtures, even after adding the liquid to the solid, they are permitted to make on the sabbath without any shinui (unusual mode) of production.

Hebrew:

Definition for solids: Changing the properties of something via heat. Liquids: Bringing a liquid's temperature to the heat threshold. 'Heat' for these purposes is at the threshold known as "Yad Soledet" (lit. Hand [by reflex] draws back [due to such heat]) which according to the Igrot Moshe (Rabbi Moshe Finestein) is = 43.3°C / 110°F.

Baking, cooking, frying, or any method of applying heat to food to prepare for eating is included in this prohibition. This is different from "preparing". For example, one can make a salad because the form of the vegetables doesn't change, only the size. However one cannot cook the vegetables to soften them for eating.

Trapping
Trapping (Animal)
Animal trapping, or simply trapping, is the use of a device to remotely catch an animal. Animals may be trapped for a variety of purposes, including food, wildlife management, hunting, and pest control...

Hebrew:

Definition: Forcible confinement of any living creature.

The Mishna does not just write "trapping"; rather, the Mishna says "trapping deer". According to at least one interpretation, this teaches that to violate the Torah's prohibition of Trapping, two conditions must be met.
  1. The animal being trapped must be a wild animal. This means that one may put a pet in a cage.
  2. The "trapping" action must seriously confine the animal. For example, closing the gate to a large yard on Shabbat cannot be trapping, even if there is a wild animal in the yard.


This creates questions in practical Halakha such as: "May one trap a fly under a cup on Shabbat?"
The Meno Netziv says that an animal that is not normally trapped (e.g. a fly, a bee, or a lizard) is not covered under the Torah prohibition of trapping. It is however, a Rabbinic prohibition, so one is not allowed to trap the animal. However, if one is afraid of the animal, one may trap it.

Animals which are considered too slow moving to be 'free' are not under this category, as trapping them doesn't change their status. As such, one is allowed to confine a snail or tortoise.

Laying traps violates a Rabbinic prohibition regardless of what the catch is.

 Shabbos 39–44

Building was the action of actually joining the different pieces together to make the mishcan. Inserting the handle of an axe into the socket is a derived form of this melakha. It is held by some that the act of Halakhic "building" is not actually performed (and therefore, the prohibition not violated) if the construction is not completed. From this, some authorities derive that it is prohibited to use electricity because, by turning on a switch, a circuit is completed and thus "built." (See "igniting a fire" below.)

Demolition
Demolition
Demolition is the tearing-down of buildings and other structures, the opposite of construction. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for re-use....

Hebrew:

Definition: Demolishing for any constructive purpose. This includes bowling, as the pins are knocked down, hopefully, during play. However, even if only gutterballs are thrown, the mere intention of knocking down pins is a violation of the prohibition against demolition. It is a matter of rabbinic debate as to whether intentionally throwing gutterballs during Shobbos is subject to the prohibition, as no demolition occurs. Commentary tends towards making this a violation as well, since the very act of bowling involves causing a machine to reconstruct the pin matrix upon each round, which action is initiated by the participating player.

 ground their prohibition of operating electrical appliances in this melakha.

Note that Judaism requires that at least one light (ordinarily candle or oil) be lit in honor of Shabbat immediately before its start.

This prohibition also was (and in many circles, still is) commonly understood to disallow operating electrical switches. One reason is that, when actuating electromechanical switches that carry a live current, there is always the possibility that a small electric spark
Electric spark
An electric spark is a type of electrostatic discharge that occurs when an electric field creates an ionized electrically conductive channel in air producing a brief emission of light and sound. A spark is formed when the electric field strength exceeds the dielectric field strength of air...

 will be generated. This spark may be thought of as a kind of fire, although since it is incidental and one does not benefit from it, it may not be a Sabbath violation at all. In any case, as science became more advanced, and the properties of fire and electricity became better understood, the former reasoning broke down: fire is a chemical reaction involving the release of energy; the flow of an electric current is a physical reaction. Therefore, some hold that the proper reason it is forbidden to complete electric circuits is because it involves construction or building (i.e., the building and completion of an electric circuit—see above). Some Conservative

It holds that the transfer of an article from a private to a public domain is Biblically forbidden; transferring an article between a semi-public to a private or public domain is Rabbinically prohibited; transferring of an article between an exempt area and any other domain is permissible; carrying an article four amos (about 1.7 m) may be forbidden in a public or semi-public domain and permitted in a private domain or exempt area; and carrying inside a private domain or between private domains may be permissible (see Eruv

). For these purposes "transferring" means "removing and depositing", so that carrying an article out of a domain and returning to the same domain with it does not constitute transferring. This may fall into the category of "wearing".

The definition of public and private domain is related to its relative amount of enclosures, not on strict ownership.

According to traditional Jewish commentators, this category of melakha (work) is mentioned in :
"Let no man leave (go out) his place on the seventh day"

 is in danger, a Jew is not only allowed, but required, to violate any Shabbat law that stands in the way of saving that person. The concept of life being in danger is interpreted broadly: for example, it is mandated that one violate Shabbat to take a woman in active labor to a hospital.

Controversy

The Shabbat rules have been criticized because they have sometimes been interpreted to mean that Jews should not violate the Sabbath in order to save non-Jews that are dying. Some critics point to the fact that the Talmud

ic principle is that their lives must not be saved, although it is also forbidden to murder them outright."

One widely debated verse from the Talmud reads "If any man saves alive a single soul in Israel, Scripture imputes it to him as though he had saved a whole world" (emphasis added). Many authorities interpret the words "in Israel" as limiting the verse to saving only Jews. The words "in Israel" appear in most versions of the Talmud, but not in others. A widely published commentary on this verse, by Rabbi Samuel Eliezer Eidels (1555–1631), reads: "This [verse] is intended to teach you that any man who saves one soul in Israel, and it is intentionally specified 'one soul in Israel', in the singular form, as this is the image of God, the Singular one of the world, and Jacob's [Israel's] form is His likeness ... but Kuttim [non-Jews] do not have the form of man, only the form of other creatures, and whoever brings about the loss of a soul among them does not lose the world, and whoever saves a soul among them neither adds nor diminishes anything in this world." Critics claim Eidels' commentary is significant because it is included in most published editions of the Talmud

Although all Rabbinical authorities agree that it is acceptable to violate the Sabbath to save the life of a non-Jew, some critics maintain that the reasons given by orthodox religious authorities to justify life-saving of non-Jews were not based on democratic ideals, but instead were to protect the Jewish religion (and the life-saver) from possible retaliation.
