(a)Rav permitted Chiya bar Ashi to weave a fishing snare on Chol ha'Mo'ed. Making a net to catch birds on the other hand, is forbidden. Why is that?

(b)Rav Yehudah permitted Ami the oven-maker, to fabricate ovens from scratch, and Rava Bar Isbi to fabricate sieves. How do we reconcile this with the Beraisa quoted by Rabah bar Shmuel, which forbids the construction of ovens on Chol ha'Mo'ed?

1)

(a)Rav permitted Chiya bar Ashi to weave a fishing-snare on Chol ha'Mo'ed, because it is an amateurish job. Making a net to catch birds on the other hand, is forbidden - because it is professional.

(b)Rav Yehudah permitted Ami the oven-maker, to fabricate ovens from scratch, and Rava bar Isbi to fabricate sieves. This is not a contradiction to the Beraisa quoted by Rabah bar Shmuel, which forbids the construction of ovens on Chol ha'Mo'ed - because that Beraisa is speaking about Chol ha'Mo'ed Succos, when the air is wet (due to the forthcoming rain-season), in which case the oven will not be completely dry and ready for use until after Yom Tov. Rav Yehudah on the other hand, is referring to Chol ha'Mo'ed Pesach, when the air is dry and the oven is ready for use on Chol ha'Mo'ed (the moment it is made).

2)

(a)Under what condition does our Mishnah permit ...

1. ... the construction of a low parapet in front of a balcony on Chol ha'Mo'ed?

2. ... cementing the cracks in an oven? What is the difference between a Ma'agilah and a Machlatzayim?

3. ... repairing a broken hinge, a hole in which the hinge swivels, a lintel, a lock or a key (of an outer door) on Chol ha'Mo'ed?

4. ... preserving food?

(b)According to Rav Yosef, a low parapet amateurishly made constitutes a wall made of laurel branches interwoven with Lulav-leaves. What does the Tana of the Beraisa say?

(c)Having informed us that one may use a wooden roller to cement cracks in an oven, it would not then be necessary for the Tana to permit using one's hands and feet. How do we therefore amend our Mishnah which currently reads 'u'Ma'agilin Osah b'Ma'agilah, b'Yad uv'Regel'?

2)

(a)Our Mishnah permits ...

1. ... the construction of a low parapet in front of the balconies on Chol ha'Mo'ed - as long as it is done in an amateurish way (which will be explained shortly).

2. ... cementing the cracks in an oven - using a Ma'agilah (a round wooden roller which anyone can use), but not a Machlatzayim (a large piece of wood [or metal, according to the Rambam] shaped something like a leg, which one uses by pressing on the cement and smoothening it - a method which is more professional than that of the Ma'agilah).

3. ... repairing a broken hinge, a hole in which the hinge swivels, a lintel, a lock or a key (of an outer door) on Chol ha'Mo'ed - as long as one does not deliberately postpone the job for Chol ha'Mo'ed.

4. ... the preservation of food - as long as it will be ready to eat by the end of Yom Tov.

(b)According to Rav Yosef, a low parapet amateurishly made, constitutes a wall made of laurel branches interwoven with Lulav-leaves. According to the Tana of the Beraisa - one may build it with stones, but without cementing it.

(c)Having informed us that one may use a wooden roller to cement cracks in an oven, it would not then be necessary for the Tana to permit using one's hands and feet. So we amend the Mishnah, to read - that one may cement the cracks with one's hands and feet, using the action of a roller, but not that of a Machlatzayim.

3)

(a)The Tana of our Mishnah permits the repair of broken locks and keys ... on Chol ha'Mo'ed. How do we initially reconcile this with the Mishnah in Ma'aser Sheni, which informs us that Rebbi Yochanan ben Zakai forbade the use of hammers on Chol ha'Mo'ed?

(b)On what grounds do we refute this answer?

(c)Rav Papa establishes our Mishnah before Rebbi Yochanan ben Zakai's decree. Rav Chisda differentiates between a saw and an ax. How does this answer differ from the answer that we just refuted?

(d)Rav Ashi answers the Kashya by establishing the Mishnah in Ma'aser Sheni like Rebbi Yehudah, and our Mishnah like Rebbi Yosi. What does Rebbi Yosi say?

3)

(a)The Tana of the Mishnah permits the repair of broken locks and keys ... on Chol ha'Mo'ed - because a carpenter uses wooden implements, which do not make much noise; whereas the Mishnah in Ma'aser Sheni, which informs us that Rebbi Yochanan ben Zakai forbade the use of hammers on Chol ha'Mo'ed - is referring to blacksmiths, who use metal implements, which make a tremendous noise (which is forbidden presumably, because it interferes with the serene spirit that pervades on Chol ha'Mo'ed).

(b)We refute this however - because then people will say that a big noise is forbidden, and a little noise is permitted (and this is not in keeping with the manner in which Chazal issue their decrees).

(c)Rav Chisda differentiates between a saw (which is permitted - because it does not make a noise at all) and an ax (which does - irrespective of whether it is made of metal or wood).

(d)Rav Ashi answers the Kashya by establishing the author of the Mishnah in Ma'aser Sheni as Rebbi Yehudah, and the author of our Mishnah as Rebbi Yosi - who maintains that every Davar ha'Aved (saving oneself a loss) is permitted on Chol ha'Mo'ed, and does not require a Shinuy (any change from the norm, and is therefore permitted, noise or no noise).

4)

(a)With which Tana does the Minhag that evolved to fix bolts into the lintel conform?

4)

(a)the Minhag that evolved to fix bolts into the lintel conforms - with Rebbi Yosi.

5)

(a)What happened to many of the fish in the River Bedisa in the town called Laba'i?

(b)On what basis did Abaye object when Rava permitted salting as many fish as they could bring home?

(c)On what grounds did Rava justify his ruling?

(d)According to the second Lashon, Rava permitted the people to catch the fish, and they salted them of their own volition. Abaye again objected to the people's actions - on the basis of our Mishnah. How did Rava justify what they did?

5)

(a)Many of the fish in the River Bedisa in the town Laba'i died - when they drained all the water by diverting its course.

(b)When Rava permitted salting as many fish as they could bring (even though this would render the fish unfit to eat on Yom Tov) - Abaye objected on the basis of our Mishnah, which limits the preserving of food to what one will be able to eat on Yom Tov.

(c)Rava justified his ruling however, on the grounds that, if they would not salt it, it would lead to a big loss (and we have already learned that saving oneself from a loss on Chol ha'Mo'ed is permitted).

(d)According to the second Lashon, Rava permitted them to catch the fish, and they salted them of their own volition. Abaye again objected to the people's actions on the basis of our Mishnah. Rava justified what they did however - on the grounds that the fish would be edible if it was washed in water many times.

6)

(a)How many times did they have to wash the salted fish before Shmuel, and later Rava, were able eat them?

(b)What did Rav quote Ada the hunter as saying when he was once served fish that was a third cooked, a third salted and a third roasted?

(c)He also quoted him as saying that fish tastes best when it is roasted with its brother, served with its father, eaten with its son and washed down with its father. What did he mean by that?

(d)Ada the hunter also told Rav two more useful facts; one of them, that one should not go to bed after eating, before having walked a considerable distance. What was the other?

6)

(a)They had to wash the salted fish - sixty times before Shmuel, and later Rava, could eat them.

(b)When Rav was once served fish that was a third cooked, a third salted and a third roasted - he quoted Ada the hunter as saying - that fish tastes best just before it goes bad.

(c)He also quoted him as saying that fish tastes best when it is roasted with its brother, served with its father, eaten with its son and washed down with its father. What he meant was - when it is roasted with salt (an extract from the sea - like the fish), served in water (into which it is placed after roasting), eaten with its juice, and washed down with water.

(d)Ada the hunter also told Rav two more useful facts: one of them, that one should not go to bed after eating, before having walked a considerable distance - and that after eating fish, cress and milk, one should rather drink water than beer, and beer rather than wine.

HADRAN ALACH 'MASHKIN BEIS HA'SHELACHIN'

11b----------------------------------------11b

PEREK MI SHE'HAFACH

7)

(a)The Mishnah discusses 'Mi she'Hafach es Zeisav, v'Iro Avel O Ones'. What does 'Mi she'Hafach es Zeisav' mean?

(b)What other example of Ones does the Tana add to the list?

(c)What does the Mishnah now permit him to do?

(d)Why is that?

(e)This is the opinion of Rebbi Yehudah. Rebbi Yosi is more lenient. What does he say?

7)

(a)The Mishnah discusses 'Mi she'Hafach es Zeisav - (is someone who has already stirred the olives in the vat), v'Iro Avel O Ones'.

(b)The other example of Ones the Tana adds to the list - is that the workers retracted before placing the olives into the vat.

(c)The Mishnah now permits him - to place a beam on them on Chol ha'Mo'ed, to begin the pressing process (and to leave it until after Yom Tov) ...

(d)... because if the olives are not pressed immediately, they will go bad.

(e)This is the opinion of Rebbi Yehudah. According to Rebbi Yosi - once the olives have been stirred, one may complete the pressing process in the normal manner (see also Tosfos DH 'Rebbi Yosi').

8)

(a)What does Rav Shisha Brei d'Rav Idi deduce from the fact that our Mishnah does not expressly permit someone who became an Avel to place the first beam on the olives that he has already turned?

(b)What does Rav Ashi say?

(c)In support of which of the two Amora'im do we bring a Beraisa?

(d)Seeing as an Avel is prohibited from working, what can he do if his olives are in the vat and going to spoil, his open barrel of wine are about to turn sour, his linen to go moldy if it is left to soak any longer or his wool to burn if it remains in the caldron?

8)

(a)Rav Shisha Brei d'Rav Idi deduces from the fact that our Mishnah does not expressly permit someone who became an Avel to place a beam on the olives that he has already stirred - that there are things that are permitted on Chol ha'Mo'ed, but forbidden to an Avel.

(b)Rav Ashi maintains - that if placing the beam on Chol ha'Mo'ed (which involves an Isur d'Oraisa), is permitted, then it should certainly be permitted in the case of an Avel (which involves only an Isur d'Rabanan).

(c)The Beraisa however (which permits others to place the beam on behalf of the Avel, but not the Avel himself) - supports Rav Shisha Brei d'Rav Idi.

(d)If an Avel sees that his olives are all going to become spoilt, his open barrel of wine to turn sour, his linen to go moldy if it is left to soak any longer or his wool to burn if it remains on the caldron - he can get others to see to all of these on his behalf, as we just learned in the Beraisa.

9)

(a)What system did they use to water all the fields in a valley?

(b)Rebbi Yehudah permitted sowing a plowed field on Chol ha'Mo'ed or sowing flax seeds on behalf of an Avel. On what grounds do the Chachamim disagree with him?

(c)Raban Shimon ben Gamliel is the most lenient of them all. What does he say?

(d)And what does he say about a professional craftsman whose services are in constant demand, a barber or a bath-attendant?

9)

(a)The field-owners would take turns to water all the fields in the valley, on a daily or weekly basis.

(b)Rebbi Yehudah permitted sowing a plowed field on Chol ha'Mo'ed or sowing flax seeds immediately on behalf of an Avel. The Chachamim disagree with him - on the grounds that a plowed field can be sown later, and as far as sowing flax is concerned, one can always sow something else later on (so that neither of them is a Davar ha'Aved).

(c)Raban Shimon ben Gamliel is the most lenient of them all. According to him - if there is no expert other than the Avel available, then he is permitted to place his oil in barrels and close them, and to take his flax from the soaking-house and the wool out of the boiling caldron, though he must do it discreetly.

(d)And he even goes so far as to permit a professional craftsman whose services are in constant demand, a barber or a bath-attendant, to operate on Erev Yom Tov.

10)

(a)If an Aris, a Choker or a Kablan become an Avel. others may do his work for him. What is ...

1. ... an Aris?

2. ... a Choker?

3. ... a Kablan?

(b)An ass-driver, a camel-driver or a sailor who becomes an Avel is forbidden to work. On what condition will he be permitted to do so?

(c)Why does the Tana of the Beraisa not require others to complete the work for him, like he ruled earlier with regard to working in the field?

10)

(a)Others may do the work for Avel who is ...

1. ... an Aris - (a share-cropper, who hires a field, and pays the owner with a half, a third or a quarter of the produce that grows each year [depending on the local custom]).

2. ... a Choker - (a share-cropper who guarantees the owner a fixed amount of grain ]so many Kurim] annually, irrespective of how much the field produces).

3. ... a Kablan - (someone who is employed to look after the field and who is paid a fixed amount, irrespective of how much the field produces).

(b)An ass-driver, a camel-driver or a sailor who becomes an Avel is forbidden to work. He will be permitted to do so however - in the event that either he or his animal is under contract to work for others to undertake a long journey.

(c)The Tana of the Beraisa does not require others to complete the work for him, like he ruled earlier with regard to working in the field - because in this case, it is the Avel himself, in his capacity of an employee, who is obligated to perform the task on hand (and if he does complete it, he will cause a loss both to himself and to his employer), unlike an Aris, a Choker or a Kablan who are self-employed.

11)

(a)'A Sechir Yom is forbidden to work even if he became an Avel after he began working that day, even in another town'. Why is he worse (in this regard) than the workers mentioned previously?

(b)What is the significance of the statement 'even in another town'?

11)

(a)'A Sechir Yom is forbidden to work even if he became an Avel after he began working that day, even in another town'. He is worse (in this regard) than the workers mentioned previously - because the Halachah permits him to retract even in the middle of the day (and the employer must hire fresh workers for the rest of the day, if necessary). Nor is his personal loss that great, since he will receive his wages for the period that he worked.

(b)The Tana mentions 'even in another town' - to inform us that, in spite of the fact that he is unknown there (thereby dispensing with the aspect of Mar'is ha'Ayin), it is nevertheless forbidden.

12)

(a)If someone handed an Avel work to do at home, he is forbidden to do it. Why is that?

(b)Does it make any difference whether he gets paid per job or per day?

(c)Under what condition may someone who is employed by an Avel to do work for him?

12)

(a)If someone handed an Avel work to do at home, he is forbidden to do it - because once he works at home, he has the authority to postpone the work and do it later ...

(b)Nor does it any difference whether he gets paid per job ('Kablanus') or per day ('Sechir Yom')

(c)Someone who is employed by an Avel may do the work - provided he does not do it in the Avel's house.

13)

(a)Meryon the son of Ravin and Mar the son of Rav Acha Brei d'Rava paired their oxen to plow together in the field. What did the latter do when he became an Avel?

(b)What did Rav Ashi comment on that?

(c)How do we nevertheless justify Mar the son of Rav Acha Brei d'Rava?

13)

(a)Meryon the son of Ravin and Mar the son of Rav Acha Brei d'Rava paired their oxen to plow together in the field. When the latter became an Avel - he removed his ox from the yoke.

(b)Rav Ashi commented that - in view of the Beraisa that we have just learned (that if the Avel is hired out to someone else, he may complete the job - in order not to cause his employer a loss), Mar the son of Rav Acha Brei d'Rava should not have adopted this stringency at Meryon's expense.

(c)We nevertheless justify Mar the son of Rav Acha Brei d'Rava - by pointing out that he was an important person, who is expected to be strict in these matters (even at the expense of others).
