(Mishnah - R. Yosi): Similarly, one whose wine was in the collection pit and he became a mourner or his workers did not come or another good reason, one can pour out his wine (from the grapes) into barrels and seal them in the regular way

R. Yehudah: One can cover the pit with wooden boards to prevent the wine from fermenting (but not pour and seal).

(Gemara - R. Zeira): The Mishnah only spoke about one who had already pressed his grapes, but if he had not yet pressed them, it is prohibited.

What is the case? If harvest time had arrived (before the festival) and he did not harvest, he damaged himself. If the harvest time had not yet arrived, there will be no loss caused if he waits until after the festival.

Rather, the harvest time had arrived and he thought that it could wait until after the festival and then realized that it could not.

It is like the case of R. Shimon bei R. Yanai who harvested a vineyard on the festival (having thought that it could wait until later). Everyone saw him and they also did the same (even though they had time before the festival). The following year, R. Shimon ignored his vineyard and it dried up. (Even though it would have been permitted to harvest, since he was an important person, he did not wish that people would mistakenly learn from him that it may always be harvested on the festival.)

R. Chiya bar Ashi quoting Rav: On Chol Hamoed, in order to catch fish for the festival, it is permitted to make a fish net made from willow branches.

R. Yehudah instructed that on Chol Hamoed, it is permitted to make sieves in order to sieve for the festival.

R. Ami instructed that on Chol Hamoed, it is permitted to make a grater for use on the festival.

Rabbanan of Kisarin: On Chol Hamoed, one may heat up earthenware pans and pots (for the first time, to make them ready to use) for cooking on the festival.

Shmuel: A large barrel may be water-sealed with pitch (since it has a large capacity, a large amount of wine will be lost if it is not sealed). A small vessel may not be sealed (as the loss is not so great). One may seal with a thin layer of pitch (it takes less effort) but not with a thick layer.

Some switch the text - a small vessel may be sealed but not a large barrel - since a small vessel only stores a small quantity of wine, sealing it is for the festival. Since a large barrel stores a large quantity of wine, its sealing is also for after the festival (long term storage).

(Mishnah): A person may bring in his fruit to save it from robbers and draw out his flax from the soaking vat to save it from being ruined, as long as he does not wait until the festival to do it.

In all cases, if he waited until the festival to attend to them, he may not benefit from them at all.

(Gemara): This Mishnah is not like R. Yehudah who said that (he cannot bring in his fruit; rather) he must sit and guard it.

R. Yaakov bar Acha quoting Rabbanan: Merchandise that will be lost may be moved on the festival. (Note: The Rosh's text reads that "merchandise may be sold''.)

R. Yaakov bar Acha quoting R. Yasa: If a caravan of market sellers came (with cheap merchandise for sale), it is permitted to buy from them in Chol Hamoed.

Question: If he knows that a caravan is coming and that he will need to reduce his prices as a result, can he sell his merchandise during the festival before this happens?

R. Mana: If he knows that he will not be able to sell without losing his profit, he is permitted to sell on the festival.

R. Yosi bar Bun: Are both the profit and the principal considered the principal, that you permit him to sell it on the festival if he will lose the profit by waiting? (Rather, he may only do this if he will lose some of the principal.)

R. Yona and R. Yosa permitted selling a boat cover on Chol Hamoed if the money is needed for the festival.

R. Yitzchak bei R. Elazar instructed R. Hoshiyah bei R. Simi when he was setting sail on a business trip - If you know that the ship is waiting for you to return and that you will use the profit that you make for the festival, you may sell on Chol Hamoed.

R. Yona of Batzra owned books. He asked R. Huna if he could sell them on Chol Hamoed.

R. Huna: If you will use the profits for the festival, such as for buying Kunditun to drink, you may sell them.

R. Chiya, friend of the Rabbanan: Merchandise (that had been given to a person to invest and that person later died) may be collected from the property of young orphans. They wished to suggest that this law only applies if there are witnesses who can attest to the fact that it was given as an investment.

Rabbanan of Kisarin quoting R. Ila: When there are no witnesses, it becomes like a deposit (and it may not be taken from the orphans).

What is the difference between it and a loan? A loan is intended to be spent, but this is not.

R. Ba bar Mamal: If I had another to vote like me, I would permitted weighing the meat of a firstborn animal with a Litra measurement. I would also permit performing Melachah on Chol Hamoed.

Surely they prohibited doing this in order to ensure that they sell the meat for cheap, and they acted deceitfully and sold it for a high price.

Surely they prohibited Melachah on Chol Hamoed in order that they could eat and drink and toil in Torah and they eat and drink and act inappropriately!

R. Yochanan: If you were mentioned to the minister and you are afraid, you may flee even on Chol Hamoed

R. Yochanan: (If you have already come to the minister), do not leave without asking his permission

R. Yochanan: I can transgress the prohibition of lending money with interest, when a Rabbinic prohibition is involve, for the sake of a gathering for a Mitzvah and for sanctifying the new moon.

In the morning, R. Yochanan would go to the Synagogue and collect the crumbs from the previous evening's celebration of the new moon and eat them. He said - My portion should be with those who ate here last night.
