Shabbos 26

1) When Nevuzeradan, the Babylonian general, exiled the Jews to Bavel, he made sure that the 'Kormim' and the 'Yogvim' remained in Eretz Yisrael.
What were the 'Kormim' and the 'Yogvim', and why did he do that?


(a) Why is it forbidden to light with ...
1. ... Tevel which is Tamei;
2. ... white paraffin;
... even during the week?
(b) What is Tzari?

(c) Why might its definition provide us with an additional reason to disqualify it from being used for the Shabbos-lights?

(a) Why does Rebbi Yochanan ben Nuri strongly object to Rebbi Tarfon, who forbids the use of all kinds of oil for the Shabbos-lights, except for olive-oil?

(b) Rebbi Yochanan therefore, permits the use of all oils - except for those forbidden by the Rabbanan (in our Mishnah) - even fish-oil and tar! Why does he need to specifically mention these two?

(c) Sumchus says that all meat extracts are disqualified, but fish-oil is Kasher.
Is that not what Rebbi Yochanan ben Nuri says?

(a) 'Tanya: Rebbi Shimon ben Elazar Omer, Kol ha'Yotze min ha'Eitz, Ein Bo Mishum Shalosh al Shalosh, u'Mesachechin Bo'.
What is Rebbi Shimon ben Elazar saying?

(b) What is the exception to this rule?

(c) Abaye maintains that Rebbi Shimon ben Elazar holds like the Tana de'Bei Rebbi Yishmael.
What does *he* say, and why must Rebbi Shimon ben Elazar hold like him?

(d) Then why does Rebbi Shimon confine his statement to what comes from a tree? He should have incorporated everything except for wool and linen?

Answers to questions



(a) From where does Tana de'Bei Rebbi Yishmael learn, that whenever the Torah writes "Beged" - by Tum'ah and by Tzitzis, it refers exclusively to a garment made of wool or linen?

(b) According to Rava, Rebbi Shimon ben Elazar agrees with Rebbi Yishmael, that a garment of wool or linen of three by three finger-breadths is subject to Tum'ah. In which case does he disagree with him?

(c) When does Tana de'Bei Rebbi Yishmael agree that Tum'ah applies even to clothes made of materials other than wool and linen?

(a) From where do we know that a woolen or linen garment even as small as three by three finger-breadths is subject to Tum'as Nega'im?

(b) From where do we know that the extra 'Vav' comes to include garments of three by three finger-breadths, and not of three by three Tefachim (since we always learn the smallest possible Chidush from a Pasuk, not the biggest)?

(c) Why should the Kal va'Chomer teach us three by three Tefachim, and not finger-breadths?

(d) Why can the extra 'Vav' not come to include garments of other materials which are three by three Tefachim, rather than wool and linen clothes of three by three finger-breadths?
