SELECTED HALACHOS RELATING TO Succos
By Rabbi Doniel Neustadt
The following is a discussion of Halachic topics related to the Parsha of the week.
For final rulings, consult your Rav.
You should dwell in a Succah (Emor 23:42)
EATING IN THE SUCCAH ON THE FIRST NIGHT
Every adult male is Biblically obligated to eat a k'zayis of
bread in a succah on the first night of Succos. The Talmud (1)
derives this obligation from the similar obligation of eating a
k'zayis of matzah on the first night of Pesach. Since these two
obligations are closely related, their halachos are similar in
many respects. Like all mitzvos, this mitzvah, too, can only be
properly fulfilled if there is prior planning and clear
knowledge of all the requirements. Let us review the pertinent
WHEN IS IT EATEN
In the late afternoon of Erev Succos, one should not fill
himself with food or wine so that he will be able to eat the
k'zayis of bread with a good appetite (2).
The k'zayis of bread [and the Kiddush that precedes it (3)] may
not be eaten until it is definitely night (4), no earlier than 50
minutes after sundown (5). If one ate before that time, he must
eat another k'zayis of bread in order to fulfill the mitzvah (6).
The k'zayis of bread may not be eaten after midnight (7).
B'dieved, though, one who did not eat before midnight should do
so after midnight and recite the proper blessing (8).
Preferably, one should sit down to eat the k'zayis of bread
immediately after coming home from Ma'ariv. Unnecessary delays
should be avoided (9).
HOW MUCH MUST BE EATEN
There are various views in the poskim about the exact
measurement of a k'zayis. Since this is a Biblical obligation,
it is proper to be stringent and eat at least 1.75 fl. oz. of
bread, though one who eats 1 oz. of bread fulfills his
There is a view in the Rishonim (10) that holds that the minimum
amount of bread one is obligated to eat in the succah on the
first night is a k'beitzah, not merely a k'zayis. Although the
basic halachah does not require the larger amount (11), still it
is proper to satisfy that view as well (12). The amount to be
eaten [to satisfy all views], therefore, is 3.5 oz. of bread (13).
The bread which is eaten [whether it is a k'zayis or a
k'beitzah (14)] must be eaten within a time-span of 3 to 4
minutes (15). No talking may take place until the full amount is
chewed and swallowed (16). L'chatchilah, it is proper to chew and
then swallow the bread in its entirety (17).
THE BASIC PROCEDURE
One is obligated to eat the minimum amount of bread even if he does not enjoy it and even if it causes him distress (18). Even a person who is classified as a choleh sh'ein bo sakanah is obligated to eat a k'zayis of bread (19).
Before eating the bread, one must have in mind that he is about
to fulfill the Biblical mitzvah of eating bread on the first
night of Succos (20). If one fails to have this intent and eats
the piece of bread as he normally does every Shabbos or Yom Tov,
it is questionable if he has fulfilled the mitzvah (21). In any
case, he should eat another portion of bread with the proper
One does not fulfill his obligation by eating cake, etc. (23)
Only bread made out of one of the five species of grain is valid.
Women are exempt from this mitzvah, but if they do eat the
required amount of bread in the succah, it is considered a
mitzvah and they may recite the blessing (24).
There are some who maintain that the bread should be eaten
without being dipped in honey (25), etc. Most poskim are not
particular about this stringency (26).
ARE WE REQUIRED TO FULFILL THIS MITZVAH WHEN IT IS RAINING?
There are many discussions in the poskim concerning the
obligation to eat in the succah on the first night of Succos if
it is raining. The following points are raised:
- If rain is falling, is one obligated to eat in the succah or not?
- If it is raining, is one obligated to wait and see if the rain will stop so that he can eat in a rain-free succah?
- If one does eat in the succah while it is raining, can a blessing be recited?
- If a person ate in the succah while it was raining and then the rain stopped, is he required to eat in the succah again?
- If a person ate in the succah while it was raining and then went to sleep, is he obligated to get out of bed to eat again once the rain has stopped?
Since there are different rulings on all of these issues, the
following, then, is a summary of the majority opinion (27):
If it is raining steadily and there is a reliable weather
forecast for rain all night, one should make Kiddush [with
shehecheyanu] and eat a k'zayis [or a k'beitzah (28)] in the
succah. No blessing over the succah is recited. The rest of the
meal is eaten inside the house (29).
If there is no reliable weather forecast and there is a
possibility that the rain will stop [e.g., it is drizzling or it
is raining on and off], it is proper to wait an hour or two for
the rain to subside (30). The poskim agree, however, that if the
delay will disturb the dignity and pleasure of the Yom Tov, or
if the family is hungry and/or tired, there is no obligation to
If the rain stops while the meal is being eaten inside the house
or even after the meal has finished, one is obligated to eat at
least a beitzah (31) of bread in the succah. Even if the rain
stops after midnight, a beitzah of bread must be eaten in the
succah. If one has already gone to bed and then the rain stops,
there is no obligation to get out of bed in order to eat in the

5 This is the generally accepted time for "night". Under
extenuating circumstances, there are those who permit eating the
bread a few minutes earlier. Since this is a Biblical mitzvah,
it is proper - weather permitting - to wait for 72 minutes after
sundown, to satisfy the views of the Rishonim who hold that
before that time it is not definitely night.
6 Mishnah Berurah 639:25. If, mistakenly, one ate the bread even
earlier than sundown, not only must he eat another k'zayis but
he must also repeat the blessing of leishev basukah.

this, one should bear in mind the reasons behind the mitzvah of
succah. According to some poskim (Bikurei Yaakov 625:3 based on
Bach), failure to have this intent invalidates the mitzvah.

obligation even if he does not have in mind the reasons for the

his understanding of the Gr"a; Harav M. Soloveitchik, quoted in
Reshimos Shiurim (Succah, pg. 92) and in Mesorah Torah Journal,

one is obligated to get out of bed in order to eat in the succah.
