Answer #1 (R. Zeira): He will make calculations for the feast on Shabbos.

Objection (Abaye): On Shabbos, one may make calculations for a Mitzvah!

Rav Chisda and Rav Hamnuna said so explicitly.

(R. Elazar): We may apportion Tzedakah to the poor on Shabbos.

(R. Yakov): We go to Batei Kenesiyos and Batei Midrashos to oversee communal concerns on Shabbos.

(R. Yakov bar Idi): We oversee mortal issues on Shabbos.

(R. Shmuel bar Nachmani): We go to theaters and stadiums to oversee communal concerns on Shabbos.

(R. Menasya): One may arrange Kidushin for his daughter and contract teachers (for Torah and a trade) for his son on Shabbos.

Answer #2 (R. Zeira): This is a decree lest one slaughter a small bird on Shabbos (in preparation for the feast).

Question (Abaye): If so, we should not allow Yom Kipur to fall on Monday, lest one slaughter a small bird on Shabbos (in preparation for the festive meal of Erev Yom Kipur)!

Answer #1: We are concerned only when one is busy preparing a meal for others.

Answer #2: The meal for the Chupah is right after Shabbos. The meal of Erev Yom Kipur is the following day, so he is not rushed.

This same concern also explains why the first Bi'ah may not be on Shabbos night. (We need not say like we said above that the concern is wounding.)

(Mishnah): A virgin is married on Wednesday.

Question: May they have Bi'ah that day?

Are we confident that if he finds that she is not a virgin, his anger will not subside so quickly, and he will go to Beis Din the next day?

Or, are we concerned lest he will calm down quickly, and therefore require that they postpone Bi'ah until the evening?

Answer: The following shows that the former is correct:

(Bar Kapara): A virgin is married on Wednesday and they have Bi'ah at night, because the Berachah to fish was given on Thursday;

A non-virgin is married on Thursday and they have Bi'ah at night, because the Berachah to man was said on Friday.

This shows that the only concern is the Berachah, not that his anger will subside.

Question: If the Berachah to fish is so important, a non-virgin should also have Bi'ah on Wednesday!

Answer #1: The Berachah to man is preferable.

Answer #2 (Beraisa): A non-virgin is married on Thursday, and Bi'ah is at night, so that the Chasan will spend three days with her before he returns to his work.

If Bi'ah was by day the fondness would pass sooner, and he might go to work the next day.

Question: Why do we need both answers?

Answer: There is no concern lest he go to his job the next day if he man is idle, or if Yom Tov falls on Friday.

(Bar Kapara): The deeds of Tzadikim are greater than the creation of Shamayim and earth.

A verse says that one hand of Hash-m made earth and one hand made Heaven, but the Mikdash is called the work of both hands.

Question (R. Chiya): "His hands formed the dry land"!

Answer: (We read "hands", but) it is written "hand".

Question: It says "Yotzru" (they formed)!

Answer (Rav Nachman bar Yitzchak): His fingers formed the land.

We find that the moon and stars are called the work of His fingers.

Question: "The firmament tells the work of His hands"!

Answer: The firmament recounts the work of the hands of Tzadikim (which is the work of His hands);

This refers to rain (for which Tzadikim pray).

(Bar Kapara): "You should have a shovel with Azenecha (your weapons)" - we can read this like Oznecha (your ears), to teach that one should stick his finger in his ear if he hears something improper.

Question (R. Elazar): Why do man's fingers resemble pegs?

Suggestion: He asks why the fingers are separate from each other.

Rejection: We learned that each has its own purpose (even for Avodah)!

The pinkie is the measure of the Choshen (breastplate of the Kohen Gadol).

The ring finger is used to take a handful (of incense or a Minchah).

The middle finger is needed to define an Amah (from its end until the elbow). The Amah is used in the Mishkan, the Beis ha'Mikdash and their Kelim.

The index finger is used to drop blood of a Chatas on the corners of the Mizbe'ach.

The thumb is where we pour blood and oil on a Metzora; or, it evens out the handful of incense or flour.

Clarification: He asks why fingers are slanted like pegs.

Answer: If one hears something improper, he can stick his fingers in his ears.

(Tana d'Vei R. Yishmael): The ear is hard but the lobe is soft, so if one hears improper things he can fold the lobe over the ear.

(Beraisa): One should not let his ears here idle words, for they are the first limbs to be singed (in Gehinom).

Question: If a woman's first Bi'ah permitted on Shabbos?

Question #1: Is (virginal) blood stored up (and Bi'ah creates an opening that allows it to leave), or is it absorbed (in the walls of the womb, and it comes due to a wound made by Bi'ah Rishonah, so this is forbidden on Shabbos)?

Version #1 - Question #2: If it is stored, does a man want the blood (this is not forbidden), or does he want to create an opening (which is forbidden)?

Question #3: If he wants the blood and he is not concerned about the opening, does the Halachah follow R. Shimon, who permits Davar she'Eino Miskaven (something unintended, but it might occur) or R. Yehudah, who forbids it?

Question #4: If the Halachah follows R. Yehudah, do we say that making an opening is destructive (and permitted) or constructive (and forbidden)?

Version #2 - Question #2: If the blood is absorbed, does a man want the blood (and Bi'ah is forbidden), or does he intend for his own pleasure (and Bi'ah is allowed)?

Question #3: If he intends for his own pleasure and the blood comes by itself, does the Halachah follow R. Yehudah, who forbids Davar she'Eino Miskaven, or R. Shimon, who permits it?

Question #4: If the Halachah follows R. Yehudah, is the wound destructive (and permitted) or constructive (and forbidden)?

Question #5: If it is destructive, does the Halachah follow R. Yehudah who permits this, or R. Shimon who forbids?
