Q

Zoreah - Sowing

A

Zoreah includes planting, sowing, or watering seeds to induce or encourage growth. This melacha is only transgressed in a place where a seed could grow. Therefore, if one drops a seed in the desert or on a well-traveled road where it would be crushed, one has not violated the prohibition of zoreah.

Q

Choresh - Plowing

A

It is prohibited to plow the ground—to level it off or make holes in it, like the holes used for planting seeds. Dragging a heavy lawn chair in one’s backyard, (a really heavy lawn chair), is considered plowing, if it makes holes in the ground, and is thus prohibited on Shabbat. However, a distinction may be made between making holes in the ground and making mere compressions in the ground. The latter, which is what wheels of a wheelchair or a baby carriage might do to the ground, is permissible on Shabbat. Pushing the ground down and consolidating it, is halachically different than puncturing the surface of the ground. So, baby carriages on a dirt roads, are OK

Q

Kotzair - Reaping

A

severing of any living plant or vegetation from its source of growth. Thus, one may not uproot plants, branches, or even just one leaf. Plucking a flower, picking fruit from a tree, vegetables from a garden, or mushrooms from the forest floor are actions all prohibited under the category of kotzair because these actions involve severing a living plant or part of a living plant from its source of growth

Q

M’amair - Gathering

A

Gathering consists of collecting natural produce into a bundle. The prohibition, in fact, only applies to natural produce - gathering manufactured products is completely permitted. So there’s no need to stop your little brother from collecting the candy bags after they have been throw at the Bar-Mitzvah boy. Actions that would fall under this category would be piling scattered fruit, putting together a bouquet of flowers, or stringing figs (something that was much more common in the time of the Mishna than it is today).

Q

Dush - Threshing

A

Its purpose is to separate kernels of grain from their husks, and it has been expanded to include the removal of any wanted item ( known as ‘ochel’) from its unwanted natural container ( known as ‘pesolet’). This has ramifications in terms of a subcategory of disha, namely s’chita, or squeezing.
One is not permitted to squeeze the juice out of a fruit on Shabbat.
However, there are a few legitimate ways to remove the juice from the fruit:
1)Suck out the juice, as it is a shinuy, or change, from the usual manner of squeezing out juice.
2)Squeeze juice out purely for the intention of improving the taste of the fruit, even if you keep the juice.

Q

Zoreh - Winnowing

A

Winnowing is a fundamental step in harvesting wheat because it separates the grain from the waste. Many commentators explain that the melacha of zoreh is similar to borer, sorting or separating, and miraked, sifting, in that the main point of each melacha is separating the bad from the good. One way of explaining the difference between the three is by the means used for each; zoreh is through wind, borer is by hand, and meraked is through a sifting device. One may not blow away nutshells from a mixture of nuts and shells.

Q

Borer - Sorting

A

It is any form of selecting or sorting inedible matter from food by hand. This includes removing undesired objects or matter from a mixture or combination such as removing spoiled cherries from a bowl of cherries or removing bones from a fish. Borer also includes the sorting of nonfood items mixed together, such as sorting dirty silverware from a mixture of clean and dirty silverware.
Sorting is only permitted when ALL of the following three conditions are met:
1) The selection is done by hand.
2) The desired objects are selected from the undesired, and not the reverse.
3) The selection is done immediately before the time of use.

Q

Tochain - Grinding

A

Tochain is defined as the act of breaking down an entity into small parts whereby it becomes suitable for a new use, such as grinding wheat into flour. Any kind of normal crushing, chopping, or grinding, by hand, or with a tool, falls under this category. There are four exceptions to Tochain: it only applies to earth-grown products; previously ground substances may be crushed again; food may be ground for immediate use; and substances may be ground in an abnormal manner.

Q

Miraked - Sifting

A

One suggestion is that meraked is the sifting specifically done with a keli, or instrument, especially designed for the purpose of straining, such as a sieve. Sifting flour to make it finer, or sifting the pebbles out of a pile of sand would be good example of miraked, while merely picking the pebbles out by hand would be termed borer

Q

Lush - Kneading

A

is the act of forming a solid or semi-solid substance of particles using a liquid. There are two steps in this process: contact of the liquid with the flour, and the mixing of the two with a kneading action. Some examples of lush are mixing water with sand to produce thick mud, mixing water and powder to make thick paste, and making plaster.it is permitted to soak matzah in soup or to dunk cookies in milk because these foods disintegrate when in contact with liquids.

Q

Ofeh/Bishul - Baking/Cooking

A

generally understood to be the causing of a change in the properties of a food or substance by use of heat. This includes cooking raw food until it becomes edible and causing change in nonfoods as well, such as the baking of bricks. If one were to place raw food on a flame, one should, and is required, to remove the pot before the raw food cooks. Generally, bishul does not occur in solid foods until the raw solid, or even part of it, becomes minimally edible. Liquids, however, since they are dramatically approved when heated, need only to be warmed and not physically changed by heat to be considered a violation of bishul. The minimum amount of heat needed to make substantial change is known as “Yad Soledet,” (hand draws back) and is the degree of heat from which a person, upon contact, reflexively removes his hand (“hot to the touch”).

Q

Gozez - Shearing

A

The cloth coverings of the Mishkan were made from wool, and the first step in the process was shearing it from the animal. The melacha consists of severing or uprooting any growing part of any creature, even if the creature is dead. The melacha truly only entails removing with an instrument such as clippers or scissors, but the Rabbis later included any type of hair removal. This melacha has a number of important implications, even for those of us who don’t own sheep. One may not comb their hair on Shabbat because a comb will definitely pull out hairs. Instead, one may gently use a soft-bristle brush. Cutting or biting one’s nails on Shabbat is also prohibited, and one may not pull off loose or dead skin.

Q

Melabain - Whitening

A

The Melacha of Melabein, literally “whitening,” is expressed through three categories of activity: Shriyah, or soaking, Shifshuf, or scrubbing, and Sechita, or squeezing. More commonly, melabein is the act of cleaning on Shabbat, which is prohibited. Here are some halachot that explains what is forbidden in each one of those categories:

1) Soaking - One may not pour anything (that includes, water, seltzer, etc.) or spray anything on a stain to loosen it or erase it from one’s clothes completely. Remember that when you spill something on yourself at lunch. Everyone’s knee-jerk reaction, of course, is to reach for the seltzer.
2) Scrubbing - This prohibition includes folding over part of one’s clothing to rub it against the stained spot in order to remove the stain. It also includes scratching out a dried stain from one’s clothes with one’s fingernail.
3) Squeezing - This category includes wringing out one’s clothes on Shabbat. The good news, though, is that the prohibition of squeezing things out does not apply to sprinkling one’s hair with water to hold down ‘the frizz.’ But, just watch yourselves. A sprinkle is OK, not a shower!

Q

Menafetz - Disentangling, Combing raw materials

A

The prohibition of menafetz applies to the act of beating compact material into separate strands. This includes one who combs wool or beats flax stalks or any similar process. Some add that menafetz also applies to loose hair, in which case combing a wig is also prohibited on Shabbat.

Q

Tzovayah - Dyeing

A

The next step is the Melacha of dyeing. Dyed wool was used for the curtains and the covers of the Mishkan. The Melacha includes coloring or darkening any material that is ordinarily colored, dyed, or painted for some useful purpose. If the coloring is only temporary, it is still rabbinically prohibited. This Melacha is the source for the prohibition of wearing makeup on Shabbat, since one is coloring the skin. Some authorities even prohibit sunbathing for this reason. Dyeing food is not considered Tzovayah because food’s primary function is to be eaten, not to serve as art.

Q

Toveh - Spinning

A

his Melacha involves twisting fibers together to make long threads. Given that none of us work in sweatshops, when would this melacha ever be relevant to us?
Well, for those of us who wear tzitzit, there comes a time when the threads of the tzitzit may fray and separate from one another. On Shabbat one may not twist the threads back together.

17
Q

Maisach - Mounting the warp

A

Warping is the first step in the creation of woven fabric. The longitudinal threads are called warp and the transverse threads are called weft. Warping entails aligning and setting warp threads firmly in position in order to allow the weft threads to pass over and under them in perfect sequence. This is an important preliminary step of all types of weaving, including lattice-work, making a simple pot holder, and basket making.

18
Q

Threading two threads

A

This melacha is one of the five steps in making cloth. Technically, it involves threading two threads through the (heddle eyes) rings in each of the two harnesses of the loom. Practically, this prohibition would apply to setting up a loom with at least two strings or threads in one direction, as one might do to make a potholder.

19
Q

Oraig - Weaving

A

The melacha of Oraig involves completing the creation of a fabric by passing the “transverse weft” thread under and over the “warp” threads. The reason these terms might sound unfamiliar is that they apply to thread mounted on a loom, a device that most of us have probably never seen. On a more practical level, on Shabbat it sometimes happens that a thread in one’s clothes becomes snagged on a hook or nail, causing the fabric around it to bunch up. Pulling and smoothing the bunched-up fabric is a direct violation of this melacha. On a less practical level, braiding shaitel (wig) hair is also prohibited because of Oraig.

20
Q

Potzai’ah - Separating

A

Separating (removing) threads (Unweaving or removing Weaves

The Melacha of Potzai’ah is removing weaved threads from a loom. Excess threads eliminated from areas that are too densly packed is also Potzai’ah.
All the Melachot from ‘mounting the warp’ to here were required for weaving the Mishkan’s curtains.
Relevance? Remember making potholders on the little square looms. The weaving would be Oreig, which is prohibited on Shabbat. Removing the finished product from the “loom” is the Melacha of Potzai’ah.

21
Q

Koshair - Tying a knot

A

There are two types of prohibited knots:
kesher uman, a craftman’s knot, and kesher shel kayama, a permanent knot.
Any tight knot that will never loosen and become undone on its own is considered a kesher uman, whereas a kesher shel kayama refers to any knot that is meant to remain permanently, even if it is a type of knot that may sometimes come undone over time. In practice, any knot that is either tight and durable (and made without any specific intention to undo it later) or one that is meant to last permanently (even if not tight or durable) is forbidden to make, and must be treated as a possible Kesher M’de’oraisa (Torah-restricted knot).
Thus, a bow-tie used for tying shoes or decorative lace is not considered a knot, and making this knot for only a day, i.e. 24 hours or less, is therefore permitted. On the other hand, if one intends to leave it indefinitely in its knotted state then it is considered a kesher shel kayama even though it is not very firm

22
Q

Matir - Untying a Knot

A

The prohibition of untying applies to cases where the knot one is untying is also prohibited. If the knot is such that tying it was a violation of a Torah law, then untying that knot is also a Torah violation; similarly, if the knot is a violation of a Rabbinical law, so too untying it is in violation of a Rabbinical law.

23
Q

Tofair - Sewing

A

abric together, which was done for the cloth coverings of the Mishkan, the Melacha of Tofair is more general and consists of combining any two separate objects into one single entity, by any means. One important concept in regards to Tofair is that an action is not considered Tofair if the connection is meant to be created and broken as part of the object’s functional design. Therefore using buttons, zippers, safety pins, and Velcro is permitted. Gluing is considered Tofair only when the gluing is meant to be permanent. As a result, the adhesive on disposable diapers can be used, while “Fun-tack,” which is often left in its position indefinitely, is prohibited.

24
Q

Ko’reah - Tearing

A

The basic concept of Ko’reah may be described as the tearing of a single object into two parts, or the detaching of the two objects that became combined as one.
Ko’reah is only possible with materials that are sewn or glued together when torn. Rope or thread is repaired by tying the ends with a knot, not by sewing of gluing. Therefore, one may cut a price tag off of a garment (discreetly), preferably with a knife.
One may tear apart food packaging, wrapping around bandages, napkins, medicines, clothing, or even toys provided that no letters or designs will be torn (Mochaik) and that no vessel is formed (Makeh B’Patish).
Milk cartons with the glued tops present a problem of Ko’reah. Some authorities see the spout as a temporary seal, and a glued joint of a temporary nature may be undone on Shabbat. However, some say that the best way to open cartons is by opening both sides, thereby ensuring that the problem of creating a vessel is addressed.

25
Q

Tzud - Trapping

A

Tzud involves trapping or confining an animal or insect, providing that the species is one that is normally trapped or hunted. According to some poskim, Tzud is one of the few melachot that can be violated even without a direct action. For instance, frightening an animal into a corner is considered tzud even if one never came in contact with it.

26
Q

Shochet - Killing

A

Shochet is the second Melacha in the series of melachot that deal with preparing skins. After trapping the animal, it is necessary to kill it in order to take the skin. Killing by any means, whether by slaughtering, stabbing or battering, not just shechita (ritual slaughter) as applied to kosher animals, would make one liable. This prohibition applies to all kinds of animals and things that come from the dirt.

27
Q

Mafshit - skinning

A

After slaughtering the animal, the next step in the process of preparing hides is to remove the hide and spread it out flat, hence the prohibition of Mafshit. This Melacha is not relevant in situations where the skin has already been cooked and is in an edible form, but rather only in cases where the skin is on a newly-slaughtered animal. Therefore, this prohibition does not apply to removing the skin of a cooked chicken (although attention must be paid to the laws of Borer, separating).

28
Q

M’abaid - Tanning

A

Tanning involves the process by which raw animal hides are preserved. Hides are soaked in potent tanning solutions until they reach a point of long-lasting durability; this would ensure that they would remain in good shape for the Mishkan. M’abaid also applies to finished leather as well as raw hides, and therefore one is not permitted to use any shoe polish which contains leather preservatives.
As per a Rabbinical restriction, the preservation of food items is also prohibited. .Salting foods is also problematic, and the Sages prohibited sprinkling salt on some foods and vegetables. According to the Shulchan Aruch (321:3), one may not salt a plate of cucumbers, radishes, peas, onions, garlic, scallions, peppers, lettuce, carrots, turnips, or string beans.

29
Q

Mesharteit - Tracing lines, Marking

A

After smoothing the processed hide of an animal, one must outline the area that is going to be cut. The act of outlining, or marking, is the Melacha of Mesharteit. This prohibition applies to skin, klaf (parchment), paper, wood, and other materials, with the exception of food. It is forbidden to mark even with your fingernail.
Example: One cannot mark a piece of paper with lines in order to write letters in a straight line.

30
Q

Memacheik - Smoothing

A

Memacheik is the method by which hair was removed from the hides used to create the walls of the Mishkan. Similar to smoothing hides, Memachaik only applies to surfaces that are firm. For example, sanding or smoothing a wooden or leather surface would be Memachaik. The prohibition of Memarai’ach applies to the smoothing of substances that can be molded i.e. wax, creams or ointments.The rabbinic prohibition also only refers to smearing. Pressing cream onto the skin, however, may be permitted, providing one is careful only to press and not to smear. This does not apply to foods.

31
Q

Mechateich - Cutting

A

Cutting hides, or any material for that matter, with one’s hands or an instrument, to a pre-measured size and shape is called Mechateich. Following the general pattern set by previous melachot involved in the tanning process, Mechateich doesn’t apply to food items, and one may cut measured pieces of fish, cake, and challah on Shabbat.
Small packets of sugar, salt, coffee, ketchup, mustard, etc., may be opened on their perforated lines because the intention is not to deliberately and skillfully follow the lines (to create a neat cut), but only to retrieve the item. However, the perforated lines on a box of tissues are meant to help produce a neat opening, and opening the box is thus Mechateich.
The Melacha of Mechateich is not to be confused with Ko’reah (tearing). Mechateich is measured cutting, while Ko’reah is not. Mechateich applies to all materials, while Ko’reah does not.

32
Q

Kotaiv - Writing two or more letters

A

This Melacha is often defined as creating meaningful images, not simply as writing. This is because, while forming two letters is generally the minimum for the prohibition of Kotaiv, forming any images of at least that size would be problematic, including painting pictures, etching a design into wood, and embroidering a design into cloth.
There are two interesting Rabbinic prohibitions that emanate from Kotaiv. One, as applicable to other melachot, is doing Kotaiv in a non-permanent fashion, such as writing one’s name with one’s finger on a windowpane. The other prohibition is from doing any activity that may lead to writing. For this reason, conducting business is problematic on Shabbat. Additionally, according to the Shmirat Shabbat KeHilchata, playing a game that generally involves writing (as in keeping score) would be problematic on Shabbat from a Rabbinic standpoint, although one does not actually plan to write.

33
Q

Mochaik - Erasing two or more letters

A

If the Mishkan’s builders erred in writing letters on the boards, they would erase them in order to write the proper ones. This Melacha is defined as erasing meaningful images. The Torah prohibition encompasses both the cleaning of a writing surface and the obliterating of letters or characters. This also applies to non-traditional ways of erasing, like blotting something out instead of erasing it. One therefore must be especially careful when opening packaging that has letters on it on Shabbat. The Melacha only applies to letters. Destroying words is not a problem.
There are a number of interesting prohibitions that arise from this Melacha. Cutting a cake with lettering in the icing may be a problem. One should be extra careful to cut between letters. However, letters that are engraved in dough, like the lettering on some biscuits, is not considered writing and may therefore be destroyed without a problem.

34
Q

Boneh - Building

A

The prohibition of building on Shabbat has wide ramifications. The main acts that are prohibited are building something attached to the ground or adding to something that is already built on the ground. Even doing a kol-shehu, a very small amount, of these actions is considered Boneh. Furthermore, fixing something, like a nail, on such a building is also prohibited.
In addition to building things that are attached to the ground, the prohibition of Boneh also covers ‘building’ something in the ground itself; for example, making a hole in a house or in a courtyard (provided that the hole is not dug solely for the dirt, in which case there is only a rabbinic prohibition against it). However, digging a hole in a field would be a violation of Choresh, plowing.

35
Q

Soiser - Demolishing

A

The 35th melocho, Sossair is essentially the reverse of Boneh, building. As the Jews traveled throughout the desert, it was necessary to build and demolish the structure of the Mishkan by taking apart the separate kerashim, planks.
The Melacha Deoraisa (Torah prohibition) applies only when the act of demolition is accompanied by an intention to rebuild eventually. However, any act of destruction (albeit unconstructive) is rabbinically prohibited because of its resemblance to the Melacha Deoraisa.

Practical cases:
One may not remove the handle of a window crank, unscrew / replace a tap filter, or replace a window screen.
It is not a problem to destroy parts of an edible food item, such as the shape of a cookie, while eating it. The reason given is that the functional use of food is for eating. Since Boneh and Soiser do not apply to the regular use and function of an object, there is no halachic problem of destroying food while eating it.

36
Q

Mechabeh and Ma-avir - Extinguishing and lighting fires

A

These two Melachot are closely related; one is the opposite of the other. Fire was used for cooking the dyes during the construction of the Mishkan and later for the Korbanot and is therefore prohibited. Mechabeh is extinguishing fire; Ma’avir is kindling fire. One practical application of these prohibitions is electricity. One cannot use electricity on Shabbat. For example, turning lights on and off is prohibited.

37
Q

Makeh - B’Patish - Striking the final blow

A

Although the Melacha stemmed from work done with a hammer, the prohibition applies to any act of completion. For example, putting shoelaces into a shoe for the first time may be prohibited on Shabbat because of this Melacha. The Melacha can also apply to liquids: carbonating water, according to some, is also Makeh B’Patish.
It is interesting to note that restoring an item is not considered an act of creation and is therefore allowed on Shabbat. For example, a pendant that fell out of a necklace may be replaced because both the necklace and the pendant were not “broken” in their separated state. The same applies to a shoelace that came out of a shoe.One prohibition is that of playing musical instruments. The Rabbis made this prohibition to prevent people from playing and accidentally tuning the instrument. This would be considered Makeh B’Patish

38
Q

Hotza’ah - Transferring

A

The Torah prohibits one to transfer (i.e., carry, throw, push, etc.) an object from a “reshut hayachid”, a private domain*, and “reshut harabim” - a public domain** and vice versa. Hotza’ah is carrying or moving something (transferring an object) between a reshut hayachid, and reshut harabim.
- Hachnasah - refers to transferring objects from a reshut harabim to a reshut hayachid.
Transferring an object either from a private domain to a public domain (Hotza’ah) or the reverse (Hachnasah) is forbidden by the Torah.
- Ma’avir Arba Amot b’Reshut harabim - carrying an object from one place in a public domain to another over a distance of at least four Amot, (appoximately 7 feet ) or more is similarly forbidden.
- Moshit, which involves “passing” an object from one reshut hayachid to another reshut hayachid through reshut harabim (as described in the Mishnah Shabbos 96a is also a Biblical prohibition.
