[On] Yom HaKippurim it is forbidden to eat, to drink, to wash, to anoint oneself, to put on sandals, or to have intercourse. A king or bride may wash their face, and a woman after childbirth may put on sandals, the words of Rabbi Eliezer. But the sages forbid it.

If one eats [an amount] the size of a large date, like it and its seed, or if he drank [an amount equivalent to a] mouthful, he is liable. All foods add up to make an amount equivalent to a date, and all the liquids add up to make a mouthful. Food and drink do not add up.

If he ate and drank in one state of unawareness, he is not obligated to bring more than one sin-offering. But if he ate and performed labor while in one state of unawareness he is obligated for two sin-offerings. If he ate foods unfit for eating, or drank liquids unfit for drinking, or drank fish-brine or fish pickling liquid, he is not liable.

[With regard to] children: they do not “afflict” them at all on Yom HaKippurim. But they train them a year or two before in order that they become accustomed to the commandments.

If a pregnant woman smelled [food on Yom Kippur], they feed her until she feels restored. A sick person is fed at the word of experts. And if no experts are there, they feed him upon his own request until he says: enough.

If one is seized by a ravenous hunger, they feed him even unclean things until his eyes light up [and he returns to health]. If one was bit by a mad dog, they do not feed him the lobe of its liver. But Rabbi Matia ben Harash permits it. Moreover Rabbi Matia ben Harash said: if one has pain in his throat, they may drop medicine into his mouth on Shabbat, because it is a possibility of danger to human life and every potential danger to human life overrides Shabbat.

If an avalanche fell on someone, and it is doubtful whether or not he is there, or whether he is alive or dead, or whether he is an Israelite or a non-Jew, they remove the debris from above him [even on Shabbat]. If they find him alive they remove the debris, but if dead they should leave him there [until Shabbat is over].

One who says: I shall sin and repent, sin and repent, they do not afford him the opportunity to repent. [If one says]: I shall sin and Yom HaKippurim will atone for me, Yom HaKippurim does not effect atonement. For transgressions between man and God Yom HaKippurim effects atonement, but for transgressions between man and his fellow Yom HaKippurim does not effect atonement, until he has pacified his fellow. This was expounded by Rabbi Elazar b. Azariah: “From all your sins before the Lord you shall be clean” (Leviticus 16:30) for transgressions between man and God Yom HaKippurim effects atonement, but for transgressions between man and his fellow Yom HaKippurim does not effect atonement, until he has pacified his fellow. Rabbi Akiva said: Happy are you, Israel! Who is it before whom you become pure? And who is it that purifies you? Your Father who is in heaven, as it is said: “And I will sprinkle clean water upon you and you shall be clean” (Ezekiel 36:25). And it further says: “O hope (mikveh) of Israel, O Lord” (Jeremiah 17:13--just as a mikveh purifies the unclean, so too does he Holy One, blessed be He, purify Israel.
