Shabbos 23


(a) Is a guest obligated to perform the Mitzvah of Ner Chanukah?

(b) What would be the easiest way for him to fulfill his obligation?

(c) And does this apply even to a married guest, whose wife is at home?

(a) What is the advantage of sunflower oil over olive oil, and what is the advantage of olive oil over sunflower oil?

(b) What made Abaye change from the former to the latter?

(a) When does one recite the Berachah over seeing a lit Menorah?

(b) Which Berachah does he recite?

(c) How many Berachos does he recite on the first night of Chanukah?

(d) He omits 'Zeman' ('Shehechiyanu'), but not 'Nes'.
Why is this?

(a) How can we say 'Asher Kideshanu be'Mitzvosav *ve'Tzivanu* Lehadlik Ner Shel Chanukah', when it is the Rabbanan who instituted the Mitzvah, and not Hashem?

(b) If one recites a Berachah over a Mitzvah de'Rabbanan, how can the Beraisa permit one to separate Ma'asros of Demai naked? How can one recite the Berachah in that state, when the Torah has written in Devarim "ve'Haya Machanecha Kadosh" - according to Abaye?

(c) So why does one then recite a Berachah over the second day Yom-Tov, which is also a Safek de'Rabbanan.

(d) How does Rava explain why no Berachah is recited over Demai?

(a) When does a house with two doorways leading into the courtyard require two Menoros?

(b) What exactly are we concerned about? Who will be likely to suspect him?

What are the four reasons for the obligation to leave Pei'ah at the end of one's field, and not in the middle?

(d) What does 'at the end of one's field' mean?
