If he takes it as a gift, his power as a creditor is not enhanced in this manner. He is not served well because he would not be able to seize property sold to a third party in order to receive his gift. So too, the widow can sell property and then decide later for what purpose she sold it.

§ The Gemara asks: How does a widow sell property to earn money for her support? Rabbi Daniel bar Rav Ketina said that Rav Huna said: She sells her late husband’s property once every twelve months and the buyer who purchased the property from her provides her with money once every thirty days. And Rav Yehuda said: She sells once every six months and the buyer provides her with money once every thirty days.

The Gemara notes: It is taught in a baraita in accordance with the opinion of Rav Huna: She sells once every twelve months, and the buyer provides her with support once every thirty days. So too, it is taught in a baraita in accordance with the opinion of Rav Yehuda: She sells once every six months, and the buyer provides her with money once every thirty days.

Ameimar said: The halakha is that she sells once every six months and the buyer provides her with money once every thirty days, in accordance with the opinion of Rav Yehuda. Rav Ashi said to Ameimar: What do you have to say about the opinion of Rav Huna? He said to him: I did not hear about this statement; that is to say, I do not hold in accordance with it.

§ The students raised a dilemma to Rav Sheshet: If a woman sells property for her sustenance, what is the halakha? Can she return and seize those very properties that she had sold, as payment for her marriage contract?

The Gemara explains: They raised this dilemma in reference to a halakha established by Rav Yosef, as Rav Yosef said: In the case of a widow who sold liened property to a third party, the property guarantee rests upon the orphans. If the property was seized from the purchasers in payment of a previous debt, then the purchasers are reimbursed by the orphans. And so too, in the case of a court that sold property belonging to the deceased, the property guarantee rests upon the orphans. It is in light of this halakha that the dilemma was raised to Rav Sheshet: What is the halakha in this case?

Is the halakha that since the property guarantee rests on the orphans, she is able to seize the property? Or perhaps the buyers are able to say to her: Granted, you did not accept upon yourself a property guarantee for everyone, and it is the heirs and not you who have to reimburse us if our property is seized; however, did you not accept a guarantee about your own actions, that you as the seller will not return and seize the property from us?

Rav Sheshet said to the one who raised the dilemma: You learned in a baraita: A widow sells the deceased’s property for her sustenance, and she continues to do so until there is nothing left except the value of her marriage contract, and she relies upon the fact that she will collect payment of her marriage contract from the remainder of the property. Learn from this that if she left property equal in value to her marriage contract, then yes, she can sell it as payment of her marriage contract; but if she did not leave property, then no, she cannot collect her marriage contract. If she could simply seize the land from the buyers, she would not need to set aside part of her husband’s property to use as payment for her marriage contract. She could sell all the land for sustenance and afterward return and seize the property from the purchasers.

The Gemara rejects this proof: But perhaps the baraita teaches us good advice, so that they will not call her a retractor and say that she is an untrustworthy individual who goes back on agreements into which she entered. However, legally, she is able to seize the property from the buyers. The Gemara answers: If that is so, and the baraita intended only to give advice, let it simply teach: She collects payment of her marriage contract from the remainder. What is the purpose of the added emphasis of: She relies? Learn from this that the baraita is worded in a precise manner and teaches that if she left property, yes, she can collect payment of her marriage contract. If she did not leave over, no, she cannot collect payment of her marriage contract.

§ A dilemma was raised before the scholars: If someone sold properties because he needed money for a certain purpose and in the end he did not need the money for that purpose, is this considered a sale conducted in error, so that the seller can renege on the deal and the sale is reversed? Or, is the sale not reversed and what is done is done?

The Gemara suggests: Come and hear a proof: There was a certain man who sold land to Rav Pappa because he needed money to buy oxen. In the end, he did not need the money and regretted having sold the land, and Rav Pappa returned his land to him. The Gemara rejects this: This is not a proof, as Rav Pappa acted in a manner that was beyond the letter of the law.

Come and hear another proof: There was a certain drought in Neharde’a during which everyone sold his mansion [appadna] in order to buy wheat. In the end, wheat arrived, driving down the price, rendering their sale unnecessary. Rav Naḥman said to them: The halakha is that the mansions are returned to their previous owners. It is evident that he holds that a sale that was prompted by the need for money is voided if it becomes clear that the seller no longer needs the money.

The Gemara answers: There too, the sale was conducted in error, as it became known that the ship with the wheat was already in the bays of the river at the time when the mansions were sold. Had they known that the ship was so close, they would not have sold their property. This is a case of an error at the time of the sale, which is different from a case where the circumstances changed after the sale.

The Gemara offers proof that the error was already present at the time of the transaction: If so, this is what Rami bar Shmuel said to Rav Naḥman when he questioned his ruling: If this is so, and the mansions need to be restored to their previous owners, you find yourself obstructing them for the future. As a result of this ruling, people will not want to buy land because they will worry that the seller will change his mind. Rav Naḥman said to him: Is that to say that it is so common, that there is a drought every day? I said that the properties are returned only in these specific circumstances. He said to him: Yes, in Neharde’a drought is a frequent occurrence.

The Gemara concludes: And the halakha is that if one sold properties for a certain purpose and in the end did not need the money for that reason, the sale is reversed.

MISHNA: A widow, whether widowed from betrothal or from marriage, sells her husband’s property when not in court.

Rabbi Shimon says: A widow from marriage sells when not in court, but a widow from betrothal may sell only in court, because she does not receive sustenance from her husband’s property. She receives only her marriage contract, and anyone who does not receive sustenance may sell only in court.

GEMARA: The Gemara elaborates: Granted, a widow from marriage may sell when not in court due to the fact that her sustenance is a pressing concern, so one does not make her wait until she finds a court that will oversee her sale.
