Shabbos 109


(a) What do the following three have in common: Alin (a plant), coriander seeds and hops?

(b) What did Rav Yosef have to say about coriander-seeds?

(c) And what praise did Rav Sheshes have for Gargira (the rocket-plant)?

(d) In which way are Matruza hops different than all other hops - with regard to Hilchos Shabbos?

(a) Rav Chisda ate meat that had been smeared with oil and roasted egg, and so did Ze'iri.
Why is this not considered Tikun Ochlin?

(b) Which similar ruling did Ze'iri issue (with regard to straining)?

(c) Why do even the disputants of the previous Halachah agree that one may not scramble slightly-roasted eggs on Shabbos?

(a) Someone who knocks his foot is permitted to soothe it with wine, but not with oil.
Why the difference?

(b) Why are the residents of Mechuza, forbidden to use even wine?

(c) By which kind of wound will either of the two above prohibitions be permitted

(a) One is permitted to bathe in the waters of G'rar, Chamsan, Asai and Teverya.
What is the Chidush of at least the first and last of these?

(b) Then why is it forbidden to bathe in the sea, in Mei Mishreh (water in which flax has been soaked) or in the Salt-Sea?

(c) How do we ultimately reconcile this Beraisa with the Beraisa which permits bathing in the Sea?

(d) Is bathing in Mei Mishreh ever permitted?

(a) In a Mishnah in Parah, Rebbi Meir considers all seas to have the Din of a Mikveh.
What does Rebbi Yehudah hold in this matter?

(b) They both agree however, that the sea does not have the Din of a spring.
What are the two basic differences between a Mikveh and a spring?

(c) What compromise does Rebbi Yossi make between Rebbi Meir and Rebbi Yehudah?

Answers to questions



(a) Why are Mei Dekalim and Kos Ikrim forbidden on Shabbos?

(b) What is 'Kos Ikrim'?

(c) Are these two completely prohibited on Shabbos?

(a) The Ezov (the sage-plant - a type of hysop) which is used to sprinkle the Parah Adumah (among other things) is called Abarsa bar Hemeg; the Ezov-Yavan (another species of hysop - known as Ezav-Yavan Abarsa bar Hing) is the one referred to in our Mishnah.
Where did they grow (according to some of Rashi's Rebbes)?

(b) It would seem from a Mishnah in Parah, that the Ezov is more likely to be Shumshuk, than Maru Chivra.
Why is that? What does the Mishnah in Parah say?

(c) The Ezov, which was eaten with seven black dates, was a cure for Kukiani.
What is Kukiani?

(d) What was the cause of the Kukiani?

(a) 'Aval Ochel Hu es Yoezer' (the pennyroyal plant) - a cure for Arkesa (worms).
Where were the worms situated?

(b) Arkesa was caused by eating, either meat roasted on coals, juicy meat or ox-meat, or nuts or fenugreek stalks.
How would all of these need to be eaten, in order to cause the worms?

(c) Alternative cures consisted of eating white cress or fasting, the latter followed by juicy meat.

  1. What did one do with the juicy meat, and how did he take it?
  2. Why do others omit the vinegar from the prescription?
(d) A final suggestion is to eat shavings from a bush, which were scraped in a downward direction.
  1. Why specifically 'downward' and not 'upward'?
  2. How did he prepare the shavings?
  3. Why should one block one's nostrils (or one's nostrils and ears) the following day, after drinking the potion?
  4. Where would he subsequently relieve himself?
(a) The Mishnah permits taking Abubra'ah (a one-shoot tree) on Shabbos. What was it an antidote for?

(b) The alternative was five roses and five cups of beer.
How were they taken?

(c) Rav Achdevai bar Ami's mother prepared one rose and one cup of beer for a man who had drunk uncovered liquid.
What did she then do with an oven? Did it work?

(d) Other possible antidotes for drinking uncovered water (which may contain snake-poison) were: a Revi'is ha'Lug of the milk of a white goat, or a sweet Esrog.
How did one prepare the latter?

(a) Urine that is forty days old (or from a forty-day old baby) is a cure for various ailments: a tiny cup-full for a hornet-sting, a Revi'is ha'Lug for that of a scorpion.
How much did they use as an antidote for ...
  1. ... snake-bite?
  2. ... witchcraft?
(b) What did Rav Shimi bar Ashi do with that man who swallowed a (very small) snake?

(c) The antidote for someone who was bitten by a snake involves the fetus of a white donkey.
What did they do with it?


  1. What do we learn from the Pasuk in Koheles "u'Poretz Geder Yishchenu Nachash"?
  2. What does that have to do with that officer, for whom all efforts to procure the fetus of a white donkey that was not a Tereifah failed?
