    This month is called Marcheshvan because there are no holidays in it, for in all months there is a holiday: in Kislev and Tevet there is Hanukkah, in Shevat there is Tu B'Shevat, in Adar there is Purim, etc. The only month that has no holiday in it is Cheshvan, therefore they call it Marcheshvan because it has bitterness (mar) that there is no holiday in it. And there are those who say, like "Mr. (Mar) So-and-so," Mr. Cheshvan to pay honor to it since it has no holiday.

The Prohibition of Performing Work on Yom Kippur

There is a Negative commandment to not perform work on Yom Kippur, as it is stated (Leviticus 16, 29) "and any work you shall not do", and it is stated (Leviticus 23, 30) "a Sabbath of complete rest it is for you" – one [verse] comes to teach about abstaining from eating and from the rest of the things forbidden on Yom Kippur because of affliction, and the second comes to teach about the prohibition of work – and one who performs work on Yom Kippur has violated a positive commandment, and transgresses a negative commandment, and if intentional is liable for Karet (spiritual excision) [Footnote 1].

A. Food-preparation work (Melakhet Okhel Nefesh), even though it is permitted on a Festival (Yom Tov), it is forbidden on Yom Kippur just like Shabbat, as it is stated regarding it (there) "any work you shall not do", and even food-preparation work is included [Footnote 2].

B. Any work for which one is liable on Shabbat, one is liable for it on Yom Kippur, and any [work] on Shabbat that is exempt but forbidden, is also forbidden on Yom Kippur. Except that [intentional violation of] Shabbat is [punished] by stoning, and [intentional violation of] Yom Kippur is [punished] by Karet. And any Muktzeh (set-aside item) that is forbidden to move on Shabbat, is forbidden to move on Yom Kippur [Footnote 3].

References and Notes

1. And so wrote RAMBAM (Maimonides) in Sefer HaMitzvot (Book of Commandments), And the 329th mitzvah is that He warned us against performing work on the Day of Atonement, and he said in it (Acharei Mot 16, Emor 23, Pinchas 29) "any work you shall not do". And one who transgresses this negative commandment intentionally is liable for Karet as the scripture explained (Emor), and if he was unintentional, he shall offer a fixed sin-offering. And the laws of this commandment were already explained in Beitzah and in Megillah (7b) and elsewhere.

And so he wrote in his composition (Mishneh Torah, Chapter 1 of Laws of Resting on the Tenth [of Tishrei], Law 1): It is a positive commandment to rest from work on the tenth [day] of the seventh month, as it is stated "a Sabbath of complete rest it is for you". And anyone who performs work on it has nullified a positive commandment and transgressed a negative commandment, as it is stated "and on the tenth, etc. and any work you shall not do". And what is he liable for doing work on this day? If he performed it willfully by his own intent, he is liable for Karet, and if he did inadvertently, he is liable to bring a fixed sin-offering.

2. Mishnah Megillah (7b) and RAMBAM (Chapter 1 of Laws of Resting on the Tenth, Law 12), and we learn this from what is stated regarding Yom Kippur, "a Sabbath of complete rest it is for you", in the same manner as stated regarding Shabbat, "and on the seventh day [it is] a Sabbath of complete rest", teaching that there is no difference between Yom Kippur and Shabbat regarding the prohibition of work.

C. And so wrote the paragon of the generation in Chazon Ovadia (High Holy Days, Laws of the Five Afflictions, Law 3), and in the sources there – Shulchan Aruch (Section 611, Subsection 2). And moving Muktzeh (set-aside items) that is permitted on Shabbat, such as bones and peels suitable for animal food, and likewise fruits designated for merchandise, nevertheless, they were strict not to move them on Yom Tov lest people come to treat it light-headedly (Beitzah 2b), nevertheless on Yom Kippur it does not apply to say so, for Yom Kippur is strict to people no less than Shabbat, as Tosafot wrote in Chullin (101b) beginning with Haizeed B'Shabbat, and one can say that Yom Kippur is stricter to people because it is a day of forgiveness and atonement.
