the other may contribute his shekel for him, i.e., it is permitted for the second individual to donate the half-shekel from his own money to the Temple on behalf of the first one, who is prohibited by the vow from deriving benefit; and he may repay his debt for him, i.e., if the one prohibited by the vow owes money to a third party, the one from whom he may not derive benefit may pay off that debt on his behalf. And he may return to him his lost object, and in a place where one takes a wage for returning a lost article, the benefit paid for the return of the item goes to the Temple treasury of consecrated property.

The Gemara discusses this mishna: Granted, he may contribute his shekel for him, as he thereby performs a mitzva. The one prohibited by the vow from deriving benefit does not derive any direct benefit from this action, as even if he did not pay the half-shekel, all Jews have a share in the communal offerings brought in the Temple, as we learned in a baraita: One performs the collection of money from the chamber with the intention that the ceremony apply to money that is lost, and money that has already been gathered but has not yet been brought to the Temple, and money that will be gathered in the future. This shows that even if one did not give a half-shekel, the communal offerings are nevertheless sacrificed in his name.

And concerning the halakha that he may return to him his lost object, he also performs a mitzva by means of this action. However, with regard to the statement that he may repay his debt for him, this is problematic because it provides a gain for the one prohibited by the vow from deriving benefit; if he did not repay the person’s debt, that person would have to pay it from his own pocket. Consequently, it should be considered as though the one prohibited from deriving benefit received money.

Rav Oshaya said: In accordance with whose opinion is this mishna? It is in accordance with the opinion of Ḥanan, who said in the mishna: He has lost his money. In other words, this is referring to a case in which he repays a debt that the other does not really have to repay at all, and therefore he is doing a favor to the creditor, not to the one who is prohibited from deriving benefit.

And Rava said: You can even say that this is in accordance with the opinion of the Rabbis, and here we are dealing with a situation where the borrower borrowed money on the condition that he need not pay it back until he chooses to do so. In that case, if the one from whom this borrower may not derive benefit repaid the debt for him, he performed a favor only to the lender, not to the borrower.

The Gemara analyzes these opinions: Granted, Rava did not say his statement in accordance with the explanation of Rav Oshaya, as he establishes the mishna in Nedarim not only in accordance with the view of Ḥanan, but also in accordance with the opinion of the Rabbis. However, what is the reason that Rav Oshaya did not say that the mishna is referring to a loan that did not have to be repaid, in accordance with the explanation of Rava? The Gemara answers that Rav Oshaya could have said to you: Although in this type of loan there is no benefit to the borrower, as he need not repay it within a certain period of time,
