הַשׁוֹחֵט חַיָּב. וְלֹא שׁוֹחִט בִּלְבַד אֶלָּא כָּל הַנּוֹטֵל נְשָׁמָה לְאֶחָד מִכָּל מִינֵי חַיָּה וּבְהֵמָה וְעוֹף וְדָג וְשֶׁרֶץ בֵּין בִּשְׁחִיטָה אוֹ בִּנְחִירָה אוֹ בְּהַכָּאָה חַיָּב. הַחוֹנֵק אֶת הַחַי עַד שֶׁיָּמוּת הֲרֵי זֶה תּוֹלֶדֶת שׁוֹחֵט. לְפִיכָךְ אִם הֶעֱלָה דָּג מִסֵּפֶל שֶׁל מַיִם וְהִנִּיחוֹ עַד שֶׁמֵּת חַיָּב מִשּׁוּם חוֹנֵק. וְלֹא עַד שֶׁיָּמוּת אֶלָּא כֵּיוָן שֶׁיָּבֵשׁ בּוֹ כְּסֶלַע בֵּין סְנַפִּירָיו חַיָּב שֶׁעוֹד אֵינוֹ יָכוֹל לִחְיוֹת. הוֹשִׁיט יָדוֹ לִמְעֵי הַבְּהֵמָה וְדִלְדֵּל עֵבָּר שֶׁבְּמֵעֶיהָ חַיָּב:

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who slaughters is liable. This does not apply only to [ritual] slaughter. Anyone who takes the life of a living beast, an animal, fowl, fish, or crawling animal - whether by slaughtering, stabbing, or beating¹ - is liable.
A person who strangles a living creature performs a derivative of slaughtering.² Therefore, if one removed a fish from the glass of water [in which it was being kept] until it died, one is liable for strangling it. [Indeed, one is liable even if one returns it to the water before] the fish actually dies. As long as [a portion of its body as wide as] a *sela*³ 30, it appears that a *sela* is approximately 2.6 or 3.2 cm in diameter according to the different opinions. between its fins becomes dry, one is liable, for it will not be able to live afterwards.
A person who inserts his hand into an animal's womb and removes a fetus [from] the womb is liable.⁴ 26a, the *Eglei Tal* quotes opinions which state that if a person performs such an act, he is liable for reaping - i.e., removing an entity from its source of nurture. The difference between these two rationales is that when an animal is prepared to give birth, the concept of reaping no longer applies, for the fetus no longer needs its mother's nurture.

footnotes:
¹ In all three of these activities, the animal dies because of bleeding. For this reason, although beating may cause the animal to die because of internal bleeding, it is included in the same category.
² Since no blood is shed, this is considered a derivative and not a מלאכה מעין.

[Mishneh Torah, Sabbath 11:2](https://torahapp.org/share/book/Mishneh%20Torah%2C%20Sabbath/r/11:2)

רְמָשִׂים שֶׁהֵן פָּרִין וְרָבִין מִזָּכָר וּנְקֵבָה אוֹ נֶהֱוִין מִן הֶעָפָר כְּמוֹ הַפַּרְעוֹשִׁין הַהוֹרֵג אוֹתָן חַיָּב כְּהוֹרֵג בְּהֵמָה וְחַיָּה. אֲבָל רְמָשִׂים שֶׁהֲוָיָתָן מִן הַגְּלָלִים וּמִן הַפֵּרוֹת שֶׁהִבְאִישׁוּ וְכַיּוֹצֵא בָּהֶן כְּגוֹן תּוֹלָעִים שֶׁל בָּשָׂר וְתוֹלָעִים שֶׁבְּתוֹךְ הַקִּטְנִיּוֹת הַהוֹרְגָן פָּטוּר:

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who kills insects and worms that are conceived through male-female relations or fleas that come into being from the dust is liable as if he killed an animal or a beast.⁵ In contrast, a person is not liable for killing insects and worms that come into being from dung, rotten fruit, or the like - e.g., the worms found in meat or those found in legumes.⁶ (see *Emunah UMada*, p. 130 ff), maintain that our inability to observe spontaneous generation is not absolute proof that such a phenomenon does not exist. Consequently, it is inappropriate for us to think of altering the halachah.
In this context, it is significant to quote the Rambam's statements, *Hilchot Shechitah* 10:13:
Similarly, with regard to the conditions that we have enumerated as causing an animal to be *trefah* (unable to live for an extended period): Even though it appears from the medical knowledge available to us at present, that some of these conditions are not fatal... all that is significant to us is what our Sages said, as [implied by Deuteronomy 17:11]: "[You shall act] according to the instructions that they will give you."
See also the introductions to Chapter 3 of *Hilchot Yesodei HaTorah* and to Chapter 4 of *Hilchot De'ot* in the Moznaim *Mishneh Torah* series.

footnotes:
⁵ This follows the Rambam's ruling that one is liable for performing a מלאכה שאינה צריכה לגופה. The authorities who differ on this principle will hold one liable only if one kills these creatures for the sake of something that one needs from their bodies.
⁶ In view of the experiments of Pasteur, there are many Rabbis who maintain that this ruling should be disregarded and we should refrain from killing any creatures on the Sabbath. Others, even contemporary authorities with scientific backgrounds, such as the Lubavitcher Rebbe Shelita

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who checks his clothes for lice on the Sabbath may rub off the lice and discard them.⁷, *Orach Chayim* 316:9. It is is permitted to kill lice on the Sabbath, for they come into being from sweat.⁸

footnotes:
⁷ See Shulchan Aruch
⁸ The difference of Rabbinic opinion mentioned with regard to the previous halachah applies in this instance as well.

[Mishneh Torah, Sabbath 11:4](https://torahapp.org/share/book/Mishneh%20Torah%2C%20Sabbath/r/11:4)

חַיָּה וְרֶמֶשׂ שֶׁהֵן נוֹשְׁכִין וּמְמִיתִין וַדַּאי כְּגוֹן זְבוּב שֶׁבְּמִצְרַיִם וְצִרְעָה שֶׁבְּנִינְוֵה וְעַקְרָב שֶׁבַּחֲדַיֵיב וְנָחָשׁ שֶׁבְּאֶרֶץ יִשְׂרָאֵל וְכֶלֶב שׁוֹטֶה בְּכָל מָקוֹם מֻתָּר לְהָרְגָן בְּשַׁבָּת כְּשֶׁיֵּרָאוּ. וּשְׁאָר כָּל הַמַּזִּיקִין אִם הָיוּ רָצִין אַחֲרָיו מֻתָּר לְהָרְגָן וְאִם הָיוּ יוֹשְׁבִין בִּמְקוֹמָן אוֹ בּוֹרְחִין מִלְּפָנָיו אָסוּר לְהָרְגָן. וְאִם דּוֹרְסָן לְפִי תֻּמּוֹ בִּשְׁעַת הִלּוּכוֹ וְהוֹרְגָן מֻתָּר:

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
It is permitted to kill beasts or insects whose bites are surely deadly, as soon as one sees them⁹ 121b explains that this leniency applies even according to the opinion of Rabbi Yehudah, who maintains that one is liable for performing a מלאכה שאינה צריכה לגופה. Because of the danger these species pose, they are allowed to be killed even when they are not pursuing a person. For it can be assumed that as soon as they become aware of a person, they will pursue him. - for example,¹⁰). flies in Egypt, hornets in Nineveh, scorpions in Adiabena, snakes in *Eretz Yisrael*, and rabid dogs in all places.
[The following rules apply with regard to] other dangerous animals:¹¹ If they are chasing a person, one may kill them.¹² mentioned in the notes on Chapter 10, Halachah 17.)If they are staying in their place or fleeing from the person, it is forbidden to kill them.¹³ If one steps on them accidentally as one is walking and kills them, this is permitted.¹⁴

footnotes:
⁹ Shabbat
¹⁰ The Rambam cites these examples to illustrate the principle he states, not to be restrictive. If other species pose mortal danger in a manner similar to the five mentioned here, the same laws apply (Kessef Mishneh
¹¹ I.e., creatures that can inflict mortal wounds, but will not necessarily do so.
¹² In this instance as well, Rabbi Yehudah would accept this leniency, for the person is concerned only with saving his life and not with the performance of the forbidden activity. (See the interpretation of Sefer HaBatim
¹³ For there is no immediate danger involved.
¹⁴ The wording used by the Rambam (based on Shabbat 121b) is somewhat problematic. The expression "if one steps on them accidentally," implies that we are speaking after the fact, after one has already crushed them, while the expression "it is permitted" appears to indicate that this license is granted at the outset.The Rashba explains that, indeed, license to kill these creatures is granted outright. One should merely make it appear that one is stepping on them accidentally. This ruling applies, however, only according to Rabbi Shimon, who does not hold one liable for performing a מלאכה שאינה צריכה לגופה. According to Rabbi Yehudah, the intent is that one may proceed without taking care to check whether one kills them or not.

הַמַּפְשִׁיט מִן הָעוֹר כְּדֵי לַעֲשׂוֹת קָמֵעַ חַיָּב. וְכֵן הַמְעַבֵּד מִן הָעוֹר כְּדֵי לַעֲשׂוֹת קָמֵעַ חַיָּב. וְאֶחָד הַמּוֹלֵחַ וְאֶחָד הַמְעַבֵּד שֶׁהַמְּלִיחָה מִין עִבּוּד הוּא וְאֵין עִבּוּד בָּאֳכָלִין. וְכֵן הַמּוֹחֵק מִן הָעוֹר כְּדֵי לַעֲשׂוֹת קָמֵעַ חַיָּב. וְאֵי זֶהוּ מוֹחֵק זֶה הַמַּעֲבִיר שֵׂעָר אוֹ הַצֶּמֶר מֵעַל הָעוֹר אַחַר מִיתָה עַד שֶׁיַּחֲלִיק פְּנֵי הָעוֹר:

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who skins [a portion of an animal's] hide large enough to make an amulet is liable.¹⁵ Similarly, one who processes [a portion of an animal's] hide large enough to make an amulet¹⁶ cites *Shabbat* 8:3, which states that one is liable for transferring a hide this size from one domain to another. Significantly, in his Commentary on the Mishnah (*loc. cit.*), the Rambam states that this refers not to the skin used to make parchment on which the amulet is written, but rather the leather used as a covering for the amulet. is liable.¹⁷
Just as one who processes [a hide is liable], so too, is one who salts [a hide], for salting is one of the methods of processing.¹⁸ 1:6. [Prohibitions associated with the forbidden labor of] processing do not apply with regard to foodstuffs.¹⁹, *Orach Chayim* 321:2-6, which mentions several Rabbinic prohibitions in connection with salting food. Note the explanation of *Shulchan Aruch HaRav* 321:2.) The *Ma'aseh Rokeach* states that the Rambam maintains, by contrast, that there are no Rabbinic prohibitions associated with salting food in this context. Note, however, Chapter 22, Halachah 10, which mentions a Rabbinic prohibition against salting food as part of the pickling process.
Similarly, one who smooths [a portion of an animal's] hide large enough to make an amulet is liable.²⁰ What is meant by smoothing? Removing the hair or the wool from the hide after [the animal's] death²¹). Note, however, Chapter 9, Halachah 7, which states that one is liable for shearing an animal's wool even when the animal is dead.
See also the Responsum of the *Beit Meir* (Vol. IV, p. 142), which explains that although the activities included in the two categories of labor are similar, their objectives differ. The object of the labor of shearing is to obtain wool, while the object of the labor of smoothing is to produce a smooth hide.
[According to the Rivosh (cited in Chapter 9, Halachah 7), shearing applies when wool is removed from a live animal, while smoothing applies when the same activity is performed after an animal has died (*Eglei Tal*). so that the surface of the hide will be smooth.

footnotes:
¹⁵ This is one of the 39 categories of forbidden labor.
¹⁶ The Maggid Mishneh
¹⁷ This is also one of the 39 categories of forbidden labor.
¹⁸ See Hilchot Tefillin
¹⁹ The Rambam's ruling differs from that of Rabbenu Chanan'el, who holds one liable for salting meat to preserve it for an extended period. (See also the Shulchan Aruch
²⁰ This is also one of the 39 categories of forbidden labor.
²¹ Apparently, the Rambam adds this phrase to distinguish between this category of forbidden labor and the category of shearing. Shearing refers to removing an animal's wool or hair when alive, while smoothing refers to performing the same activity after the animal's death (Yesodei Yeshurun

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who separates *duchsustos* from *k'laf*²² 1:7-8, where the Rambam explains that a hide used for parchment is divided in half. The thin upper side of the hide where the hair grows is called *k'laf*. The thick portion on the side of the flesh is called *duchsustos. Tefillin* should be written on *k'laf*, while *mezuzot* should be written on *duchsustos*.
At present, the parchment used for writing sacred articles is no longer processed in this fashion.is liable for [performing] a derivative [of the forbidden labor] of skinning. A person who separates [a portion] from a hide large enough to make an amulet is liable.²³. Its addition appears to be a printing error.
A person who treads upon a hide with his feet until it becomes hard, or one who softens it with his hands, extending it, and leveling it as the leather workers do is liable for [performing] a derivative [of the forbidden labor] of processing.²⁴
A person who pulls a feather from the wing of a fowl is liable for [performing] a derivative [of the forbidden labor] of smoothing. Similarly, a person who smears a poultice of even the smallest size, beeswax,²⁵ tar, or other entities that are smeared until a smooth surface is produced is liable for [performing a derivative of the forbidden labor of] smoothing.
A person who rubs a hide that is suspended between pillars is liable for smoothing.²⁶ cites the Jerusalem Talmud (*Shabbat* 7:2), which explains that preparation of the hides used for the Sanctuary involved suspending them on pillars and rubbing them so that their surface would be smooth.

footnotes:
²² See Hilchot Tefillin
²³ This phrase is not included in the early manuscripts and printings of the Mishneh Torah
²⁴ See Chapter 23, Halachah 10, for Rabbinical prohibitions associated with leather working.

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who cuts [a portion] from a hide large enough to make an amulet is liable,²⁷ provided he cuts with a specific length and width in mind. Cutting in this manner is considered as labor [forbidden on the Sabbath]. If, however, one cuts with a destructive intent,²⁸ or without a precise measure, doing so either without thought entirely²⁹ or for pleasure,³⁰ he is not liable.
A person who trims [the down from] a wing [of a fowl]³¹ 74b). is liable [for performing] a derivative [of the forbidden labor] of cutting. Similarly, one who planes³², who contrasts this halachah with Chapter 10, Halachah 16. (See the notes on that halachah.) a beam of cedar wood is liable for cutting. Similarly, anyone who cuts a piece of wood or a piece of metal is liable for cutting.
A person who takes a small piece of wood³³ and trims it to use as a toothpick or to pry open a door is liable.³⁴ and others question the Rambam's ruling, noting that according to *Beitzah* 33a-b, it would appear that one is liable only if one trims a piece of wood with a utensil. Significantly, however, the *Magen Avraham* 322:4 quotes the Rambam's decision without objection.

footnotes:
²⁷ This is one of the 39 categories of forbidden labor.
²⁸ As explained in Chapter 1, Halachah 17, anyone who performs a forbidden labor for a destructive intent is not liable.
²⁹ As explained in Chapter 1, Halachah 11, anyone who performs a forbidden labor casually, without intent, is not liable.
³⁰ Rav Kapach explains that here also the intent is performing the activity for the sake of tension release, without any concern for what one is doing.
³¹ To use in stuffing a pillow or a blanket (Rashi, Shabbat
³² Our translation is based on the gloss of the Maggid Mishneh
³³ As is obvious from the following halachah, this refers to a twig or piece of wood that is not fit to be used as food for an animal.

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
Any article that is fit to be used as animal fodder³⁵ and other *Rishonim* differ. - e.g., straw, soft grasses, palm branches, and the like, may be trimmed on the Sabbath, because the the concept of preparing a utensil does not apply in this context.
It is permitted to break fragrant branches [by hand] for the sake of their scent³⁶ (*Orach Chayim* 322:5) states that this is permitted "for the sake of a sick person." Nevertheless, the conclusion of the later authorities is that a healthy person may also do so (*Mishnah Berurah* 322:16). although they are hard and dry. One may strip [their bark] as one desires, regardless of whether one strips [the bark] of a small branch or a large branch.

footnotes:
³⁵ Although the Rambam's ruling is accepted as halachah by the later authorities, the Sefer Mitzvot Gadol

A person who writes one large letter the size of two [ordinary] letters is not liable.⁴² 340:4, *Mishnah Berurah* 340:12). In contrast, a person who erases one large letter in a place where two letters can be written is liable.⁴³
A person who wrote one letter that concluded a scroll is liable.⁴⁴ 104b, the source for this halachah, who maintain that, in this instance, one is liable for performing the labor מכה בפטיש, completing an article. From the Rambam's wording, however, it appears that he holds him liable for writing.
We see a similar decision with regard to the forbidden labor of weaving. In Chapter 9, Halachah 18, the Rambam writes that one is liable for weaving one thread if by doing so, one completes a garment (Rav Kapach). A person who writes for the sake of ruining the parchment is liable,⁴⁵ for one is liable for the writing itself⁴⁶ and the surface on which [the letters] are written is not significant. If one rubs out writing with the intent of ruining [the writing surface], one is not liable.⁴⁷
Should one rub out ink that fell on a scroll or rub out wax that fell on a writing tablet,⁴⁸ 104b). one is liable⁴⁹ and others who explain that one is liable for smearing the wax (see Halachah 6). Most authorities, however, accept the Rambam's ruling that one is liable for erasing. if [the rubbed out] portion is large enough for two letters to be written upon it.

footnotes:
³⁷ This is one of the 39 categories of forbidden labor.
³⁸ One is liable for writing two letters because this resembles the activity necessary for the construction of the Sanctuary. A mark was made on each of the sides of the walls, so that it would be used to match the same walls to each other every time the Sanctuary was erected (Shabbat
³⁹ The same also applies to a person who writes two numerals (Shulchan Aruch HaRav
⁴⁰ One's intent need not be to write on the Sabbath itself. As long as one erases with the intent of writing, one is liable regardless of when one actually writes (Mishnah Berurah
⁴¹ This is also one of the 39 categories of forbidden labor. If a mark was made in error on one of the walls, it was erased so that the correct mark could be made.
⁴² For he has only written one letter. One is not liable until one writes two letters, regardless of their size. Nevertheless, writing even a single letter is considered as חצי שיעור (the performance of half the forbidden measure of a prohibition) and forbidden according to the Torah itself (Shulchan Aruch HaRav
⁴³ For his erasure is sufficient to enable two letters to be written.
⁴⁴ In this instance, although only one letter was written, the act is significant, because it completed an entire scroll. There are commentaries on Shabbat
⁴⁵ I.e., one writes an ordinary letter on parchment fit to write a Torah scroll (Rav Kapach).
⁴⁶ Although one has ruined the parchment and thus there is a destructive aspect to one's activity, since the words one wrote are significant, one is liable.
⁴⁷ For the entire purpose of the labor of erasing is to prepare a writing surface for use.
⁴⁸ In Talmudic times, the word פנקס referred to a book of tablets coated with wax upon which merchants would write with a stylus (Rashi, Shabbat
⁴⁹ For erasing. With this act, one prepares a writing surface. Note the Sh'vut Ya'akov

One is liable for writing in any language and with any characters,⁵¹ 306:11) quotes the *Or Zarua,* who states that one is liable for writing only when one writes in the Assyrian script (i.e., the Hebrew script used for Torah scrolls) or in the classic Greek script. Note, however, the *Noda BiY'hudah (Orach Chayim*, Vol. II, Responsum 32) and the *Be'ur Halachah* 306, who refute the *Or Zarua's* opinion and state that it is not accepted by others. And note the *S'dei Chemed* (*ma'arechet kaf*, sec. 111), who brings other opinions in support of the *Or Zarua*. or even for making two marks.⁵² 12:3), the Rambam explains the term "signs" as referring to the use of letters as numbers - e.g., א for one, ב for two.
The *Maggid Mishneh* interprets these "signs" as referring to symbols that are not letters, but are significant to a reader, such as the reversed *nunnim* found in the Torah, Numbers 10:35-36. (See also Halachah 17 and *Shulchan Aruch HaRav* 340:7-8.)

footnotes:
⁵⁰ All these pairs of letters have meaning. Hence, one is liable. If, however, one writes a pair of letters that has no meaning, even if it is the beginning of a word - e.g., אא, one is not liable (Maggid Mishneh
⁵¹ It is necessary for the Rambam to mention both other languages and other characters. Otherwise, one might think that with regard to other languages, one is liable only for writing words from other languages when one transliterates them into Hebrew characters - or conversely, that one is liable for writing with other characters only when writing Hebrew words. With the wording he chose, the Rambam makes it clear that one is liable even when one writes words from another language in the characters of that language.It must be emphasized that there are authorities who differ with the Rambam's decision.

he writes two letters on two pages of a writing tablet that are not read as a single unit.⁵⁷ 12:5), the Rambam emphasizes that letters must be on the same line to be able to read as a single unit. (See also *Shabbat* 104b, which emphasizes that the distance between the two letters can also be a significant factor.)
When a person writes [two letters] in two corners [of the walls of a house] or on two pages of a writing tablet and they can be read as a single unit,⁵⁸ he is liable.

If a person took a parchment or the like and wrote one letter upon it in one city and traveled on that same [Sabbath] day to another city where he wrote another letter on another scroll, he is liable.⁵⁹ states that this ruling, based on *Shabbat* 104b, applies even when it is necessary to fold the two parchments so that the two letters can be placed in juxtaposition to each other.

If one was checking a single letter and divided it, [creating] two [letters], one is liable; for example, one divided the connecting lines of a *chet*, thus creating two *zeinim*.⁶² 340:8 mentions that a person who writes a *zayin* or any other of the letters שטנ"ז ג"ץ that require *taggim*, "crowns," without these crowns is not liable. From this halachah, it would appear that the Rambam does not accept this ruling, for the *zeinim* created when the connecting lines of a *chet* are divided do not have crowns. The same applies in all similar situations.⁶³ 104b mentions erasing the projection in the right corner of a *dalet* to create a *reish*.

A person who writes with his left hand, with the back of one's hand,⁶⁴ 104b, interprets this to mean that the person holds a pen in his hand and turns his hand upside down to write.
Based on this source, the expression כלאחר יד is used throughout the Rabbinic literature on the Sabbath laws to mean "in an unusual manner." with his feet, his mouth, or with his elbow, is not liable.⁶⁵
A left-handed person who writes with his right hand - which for him is equivalent to other people's left hand - is not liable. If he writes with his left hand, he is liable. A person who is ambidextrous⁶⁶ is liable regardless of whether he writes with his right or left hand.
When a child holds the pen and an adult holds his hand and moves it, causing him to write, the adult is liable. When an adult holds a pen and a child holds his hand and moves it, causing him to write, the adult is exempt.

footnotes:
⁶⁴ Rashi, Shabbat
⁶⁵ A person is liable for performing a forbidden labor on the Sabbath only when he does so in an ordinary manner. Although there is a Rabbinic prohibition against performing a forbidden labor in an unusual manner, one is not held liable.
⁶⁶ The precise translation of the Rambam's wording is "uses both of his hands with equal dexterity." On this basis, there is room for question regarding a left-handed person who writes with his right hand, but less comfortably than he does with his left hand. Is he liable for writing with his right hand on the Sabbath or not?

**Mishneh Torah, trans. by Eliyahu Touger. Jerusalem, Moznaim Pub. c1986-c2007:**
A person who writes is not liable until he writes with a substance that leaves a permanent mark⁶⁷ 340 who quotes the opinion of the Rashba (*Shabbat* 115b) which explains that permanency in this context refers to writing that will last an ordinary period of time. - e.g., with ink,⁶⁸ 1:4, the Rambam describes the preparation of ink as follows:
One collects the vapor of oils, of tar, of wax, or the like, [causes it to condense,] and kneads it together with sap from a tree and a drop of honey. It is moistened extensively, crushed until it is formed into flat cakes, dried, and then stored.
When one desires to write with it, one soaks [the cakes of ink] in gallnut juice or the like and writes with it. Thus, if one attempts to rub it out, he would be able to.
 black tint,⁶⁹ vermilion,⁷⁰ 12:4, *Megillah* 2:2), the Rambam translates this term into Arabic. Rav Kapach states that the Arabic term he uses refers to red colored clay used for drawing. gum, vitriol,⁷¹), the Rambam describes these substances, using Arabic terms which Rav Kapach translates as referring to saps from trees that are yellow and green in color. When they are mixed with gallnut juice, they turn black, as the Rambam mentions in Chapter 9, Halachah 14. and the like - on a surface on which the writing will remain preserved - e.g., a skin, parchment, paper, wood,⁷² and the like.
[In contrast,] a person is not liable if he writes with a substance that does not leave a permanent mark - e.g., beverages or fruit juice - or if he writes with ink and the like on a substance like vegetable leaves where the writing will not be preserved. One is liable only when writing with a substance that leaves a permanent mark on a surface where that mark will be preserved.
Similarly with regard to [the forbidden labor of erasing]: A person who erases is liable only when erasing writing that would leave a permanent mark from a surface where that mark will be preserved.⁷³

footnotes:
⁶⁷ As mentioned in Chapter 9, Halachah 13, "Whenever one performs a labor that does not have a permanent effect on the Sabbath, one is not liable." To apply a principle mentioned in the notes to that halachah, if the writing will remain on the Sabbath itself, even if it will fade afterwards, one is liable.See also the Be'ur Halachah

⁷² As mentioned previously, the forbidden labor of writing has its source in the letters written as symbols for the walls of the Sanctuary.

A person who writes on his skin is liable, because his flesh is [comparable to an animal] hide.⁷⁴ Even though the warmth of his flesh will cause the writing to fade afterwards, this is comparable to writing that was erased.⁷⁵ In contrast, a person who engraves the forms of letters onto his skin is not liable.⁷⁶ 12:4), the Rambam writes that the person is exempt, because engraving on human skin is not an ordinary way of writing.
A person who cuts out the form of letters on a hide is liable. In contrast, a person who makes a mark in the shape of letters on a hide is not liable.⁷⁷ 340 and others, it appears that this refers to a mark that is made with a stylus or the like that will not remain permanently on the hide. (Note the contrast to *Hilchot Gerushin* 4:7.)
A person who traces over letters that were written with vermilion with ink is liable for two [transgressions]: one for writing and one for erasing.⁷⁸ [In contrast,] a person who traces with ink over letters that were written with ink,⁷⁹ who traces with vermilion over letters that were written with vermilion, or who traces with vermilion over letters that were written with ink, is not liable.

footnotes:
⁷⁴ A surface on which writing would be preserved, as mentioned in the previous halachah.
⁷⁵ The writing is considered permanent, because the body's heat is considered as an external force that wipes out writing that, in and of itself, would remain permanently.

⁷⁷ From the Be'ur Halachah
⁷⁸ Letters written with ink are much more attractive and distinctive than letters written with vermilion. Nevertheless, letters written with vermilion are also significant.

Making designs is a derivative [of the forbidden labor] of writing. What is implied? A person who makes designs or who creates forms⁸⁰ 340, who questions whether one must make two designs to be held liable (as one is liable only when one writes two letters) or one is liable for making a single design. It is explained that from the Jerusalem Talmud (*Shabbat* 7:2), it appears that a single design is sufficient. on a wall⁸¹. Significantly, some authoritative manuscripts use the Hebrew כחול, meaning "blue," rather that כותל meaning "wall." According to this version, the halachah would read "One who makes designs and forms with blue, red and other [colors] of the like...." or with red color and the like as artists do is liable [for performing a derivative of] writing.⁸² Similarly, a person who erases a design for the sake of correcting [it]⁸³ is liable [for performing] a derivative [of the forbidden labor] of erasing.
A person who rules a line in order to write two letters below that line is liable.⁸⁴ Carpenters who draw a red line on a beam to enable them to saw evenly perform a derivative of ruling a line.⁸⁵ 7:2), it would appear that the category of labor of ruling lines is associated with writing only. This is somewhat difficult, because writing *per se*, was not performed in the construction of the Sanctuary. Rashi, *Shabbat* 75b, states that ruling lines was necessary to cut the hides carefully. According to his opinion, it is possible to say that ruling a line in order to saw in a straight line would be considered as the forbidden labor itself and not merely a derivative. See also *Shulchan Aruch HaRav* 340:11. Similarly, stonemasons who [make lines] on a stone so that they will cut it evenly [perform a derivative of ruling a line.]
One is liable regardless of whether the line one rules is colored or without color.⁸⁶
