Beitza 29a
1- We learned about the 6 places in Sha”s where a Halacha is stated. Some were said by Rav Malkiyo the others by Rav Malkiya.
In order to remember who said what the Gemara suggests 2 ‘memorization clues’:
שפוד שפחות וגומות
Or:
בלורית אפר מקלה וגבינה
2- The Mishnah states that a person may not ask his butcher on Yom Tov to give him a Dinar’s worth of meat. Rather, the butcher must first slaughter the animal and then divide the portions. The Gemara explains that when the animal is divided, each person who wants a share of the animal must say that he wants “one portion” or “half a portion” of meat; he should not say that he wants “one Dinar’s worth” or “half a Dinar’s worth” of meat.
In other words, the only permissible way to divide meat is by distributing standard size cuts.
The Gemara then enumerates various measurements of different localities of Bavel on how they would request meat from a butcher on Yom Tov.
סורא-תרטא
בגרש – חלקא
בפומפדיתא – אוזיא
בנהר – פקוד
מתא מחסיא – רבעא
3 – The Mishnah discusses the permissible methods of “purchasing” other products from a merchant. Two opinions of the Tanna Kamma and Reb Yehuda are stated but their wording is a bit perplexing. Thus.
4 – Clarifying the Mishnah R’ Yehudah in the name of Shmuel explains that Tanna Kamma maintains that the prohibition applies only to measuring utensils currently in use for measuring, whereas R’ Yehudah maintains that even a utensil that will eventually be used for measuring is included.
This, our gemara says, indicates that R’ Yehudah is strict regarding issues of simchas Yom Tov whereas Rabannan are lenient. A contradiction is presented against each opinion from the Mishnah on the previous page.
Both contradictions are resolved as Rava explains that Tanna Kamma maintains that the only restriction is not verbalizing the name of the measure, whereas R’ Yehudah maintains that one is not even permitted to use a measuring utensil.
5- We spoke a bit about Chanukah.
When one lights just one candle per household on all 8 days the Mitzvah of Chanukah is done!
Mehadrin and/or Mehadrin min HaMehadrin requires one candle per person and adding an additional candle per night.
So if after lighting one candle the Mitzvah is done then many interesting questions arise:
A- Can the oil of the candles other than the first be used for non Chanukah purposes? [ I think שו”ת כתב סופר]
פסחים ז: אמר רב יהודה אמר שמואל כל המצוות מברך עליהן עובר לעשייתן
B- The general rule is that a Brachah must be made prior to the Mitzvah. If one forgets and does the Mitzvah first, like eating Matzoh, the Brachah cannot be said following the Mitzvah.
The exception to this rule is if the Mitzvah is ongoing. Such as Sukkah. If one begins to eat in a Sukkah and forgets to make a Leishev Basukkah he may say it even after the meal since the sitting in the Sukkah is continuous. Ditto with Tefillin as long as one has them on himself.
Now if one lights, say on the fifth night, the first candle and then realizes that he didn’t make a Brachah. He missed the saying the Brachah for the ‘Mitzvah’ which is the first one only.
Can he now say a Brachah on the remaining four which are only a הידור?
Or perhaps because there is a Mitzvah for the candles to burn עד שתכלה רגל מן השוק even the first candle is ‘ongoing’?
See here in the responsa by Reb Akiva Eiger.
6- We spoke about why we do not mention anything about Chanukah and Purim in the Brachah after eating cake and/or drinking wine.
