On Yom Kippur, a person is liable for eating [an amount of] food that is fit for humans to eat1 and is equivalent to the size of a large ripe date2 - i.e., slightly less than the size of an egg.3 All foods [that one eats] are combined to produce this measure.

Similarly, one who drinks a cheekful of liquid fit to be drunk by humans is liable. The size of a cheekful is [not a standard measure,] but rather dependent on the size of the cheek of every individual.

What is meant by a cheekful? Enough [liquid] for a person to swish to one side of his mouth and for his cheek to appear full. For an ordinary person, this measure is less than a revi'it.4

All liquids [that one drinks] are combined to produce this measure. Foods and liquids are not combined in a single measure.5

One is liable for karet for eating on Yom Kippur if one eats food that is fit for human consumption, regardless of whether it is permitted or forbidden.6 [This includes] piggul,7 notar,8 tevel,9 the flesh of an animal that died without ritual slaughter, the flesh of an animal that is trefah,10 fat, or blood.11

If a person eats or drinks less than the above-mentioned measures, he is not liable for karet. Although the Torah forbids partaking of less than the measure [for which punishment is given], one is not liable for karet unless [one partakes of] that measure.12

A person who eats or drinks less than the minimal measure is given "stripes for rebellion."


אָכַל אוֹ שָׁתָה פָּחוֹת מִשִּׁעוּר זֶה אֵינוֹ חַיָּב כָּרֵת. אַף עַל פִּי שֶׁהוּא אָסוּר מִן הַתּוֹרָה בַּחֲצִי שִׁעוּר אֵין חַיָּבִין כָּרֵת אֶלָּא עַל כַּשִּׁעוּר. וְהָאוֹכֵל אוֹ הַשּׁוֹתֶה חֲצִי שִׁעוּר מַכִּין אוֹתוֹ מַכַּת מַרְדּוּת:


[The following rules apply when] a person eats a small amount, [pauses,] and eats again: If the time from when he begins eating until he concludes eating is less than the time it takes to eat an amount of bread and relish equal in size to three eggs, [the food that he eats] is included in the same measure.13 If not, it is not included in the same measure.14

[Similar rules apply when] a person drinks, [pauses,] and drinks again: If the time from when he begins drinking until he concludes drinking is less than the time it takes to drink a revi'it,15 [the liquid that he drinks] is included in the same measure. If not, it is not included in the same measure.

When a person eats foods that are not fit for human consumption - e.g., bitter herbs or foul-tasting syrups - or drinks liquids that are not fit to to be drunk - e.g., fish brine, pickle brine16 or undiluted vinegar - he is not liable for karet17 even if he eats or drinks a substantial amount. He should, however, be given "stripes for rebellion."

Mishneh Torah (Moznaim)

Featuring a modern English translation and a commentary that presents a digest of the centuries of Torah scholarship which have been devoted to the study of the Mishneh Torah by Maimonides.


A person who drinks vinegar mixed with water is liable. One who chews dried pepper, dried ginger, or the like is not liable. [If, however, one chews] fresh ginger, one is liable.18

A person who eats the leaves of the vine is not liable,19 but one who eats the buds of the vine is liable.20 What is meant by the buds of the vine? The buds that have sprouted in Eretz Yisrael from Rosh HaShanah until Yom Kippur. If they sprouted earlier, they are considered as wood, and the person is not liable. The same rules apply in all analogous situations.

When a person eats roast meat that has been salted, the salt is included in the mass of the meat.21 Similarly, brine on a vegetable is included,22 because condiments that make food fit to be eaten and are mixed together with the food are considered to be part of the food.

If a person was already sated [because he] had overeaten to the extent that he was jaded by food, and then ate more,23 he is not liable. It is comparable to a person who eats food that is not fit for consumption. Although this additional amount is fit to be eaten by a person who is hungry, it is not fit for a person who is sated to this extent.24

When a person who is dangerously ill25 asks to eat on Yom Kippur, he should be fed26 because of his request until he says, "It is enough,"27 even though expert physicians say that it is unnecessary.28

When the sick person says that it is unnecessary for him to eat,29 and a physician says that it is necessary, he should be fed according to [the physician's] instructions, provided the physician is an expert.30

When one physician says that it is necessary [for a sick person to eat], and another physician says that it is unnecessary, the person should be fed. If several physicians say that it is necessary [for a sick person to eat], and other physicians say that it is unnecessary, [the ruling] follows the majority, or those with the most expertise.31 [This applies] provided the sick person does not himself say that it is necessary [for him to eat]. If, however, he makes such a statement, he should be fed.

If the sick person does not say that he must [eat], the physicians were divided on the issue, they were all experts, and an equal number took each side, he should be fed.

When a pregnant woman smells food, [and is overcome by desire for it,] we should whisper in her ear that today is Yom Kippur.32 If this reminder is sufficient to calm her senses, it is desirable; if not, she should be fed until her desire ceases.

Similarly, if a person is overcome by ravenous hunger,33 he should be fed until he sees clearly. He should be fed immediately, even if it necessitates giving him non-kosher meat34 or [meat from a] loathsome species.35 We do not require that he wait until permitted food becomes available.

[From the time] a child is nine or ten years old36 [onward], he should be trained [to fast] for several hours. What is implied? If he is used to eating two hours after daybreak, he should be fed in the third hour. If he is used [to eating] after three hours, he should be fed in the fourth. According to the child's stamina, we should add hours to his anguish.

When a child is eleven years old, whether male or female,37 it is a Rabbinic ordinance that he complete his fast so that he be trained in [the observance of] the mitzvot.

A female who is twelve years old and one day38 and a male who is thirteen years old and one day, who manifest [signs of physical maturity - i.e.,] two [pubic] hairs, are considered to be adults with regard to [the observance of] all the mitzvot, and are obligated to complete their fast according to the Torah. If, however, they did not manifest [signs of physical maturity], they are still considered to be minors, and are obligated to complete their fast only by virtue of Rabbinic decree.39

A child who is less than nine years old should not be afflicted at all on Yom Kippur, lest this lead to danger.40
