הזהיר מעשות מלאכה ביום הכפורים. והוא אמרו כל מלאכה לא תעשו. והעובר על לאו זה בכרת כמו שבאר הכתוב. ואם היה שוגג חייב חטאת קבועה. והתבארו משפטי מצוה זו במסכת ביצה ובמגילה וזולתם. (שם, שם):

**Sefaria Edition 2021, Translated by Rabbi Francis Nataf:**
He prohibited doing work on Yom Kippur. And that is His saying, "you shall not do any work" (Leviticus 23:28). And one who transgresses this negative commandment is [punished] with excision, as is explained in Scripture. But if it was inadvertent, he is liable for a fixed sin-offering. And the regulations of this commandment have been explained in Tractate Beitzah, Megillah and other ones besides them. (See Parashat Emor; Mishneh Torah, Rest on a Holiday 1.)
