Talmud - Nedarim 35a נדרים ל״ה א׳

The Gemara raised an objection to Rava. If another person said to him: Lend me your cow, and the owner answered and said to him: Every cow that I purchased other than this one, which I need, is konam for you; or if he said: My property is forbidden to you if I have a cow other than this one, and in fact, he owns other cows; or if another said to him: Lend me your spade, and the owner of the spade said to him: Every spade that I have that I purchased is konam for you; or if he said: My property is forbidden to me if I have a spade other than this one, and it is discovered that he has another spade and the konam takes effect, then during the life of the one who vowed, the cow or the spade is forbidden to the subject of the vow. If the one who vowed died or if the cow or the spade was given to the subject of the vow as a gift, it is permitted. Apparently, the konam is in effect only as long as the property is in his possession.

Rav Aḥa, son of Rav Ika, said: It is referring to a case where it was given to the subject of the vow by another person. The one who vowed did not give him the gift directly. He sold or transferred the item to a third party, who gave it to the subject of the vow as a present. Since the property left the possession of its owner before it was given to the subject of the vow, the prohibition does not take effect upon it.

The Gemara states that Rav Ashi said: The language is also precise, as it teaches: That was given to him, and it is not taught: That he gave it to him. This indicates that this halakha applies specifically to a gift that was given to him by a third party, but not by the one who vowed.

§ Rava raised a dilemma before Rav Naḥman: Is there liability for misuse of consecrated property in cases of konamot or not? Since the legal status of an item that was rendered a konam is like that of consecrated property in that it is forbidden to the one who one vowed, is it like consecrated property in every sense, including liability for misuse of consecrated property?

Rav Naḥman said to him: You learned this halakha from a mishna (33a): In a place where one takes payment for returning a lost item, that benefit that he receives for returning the item should fall into the category of consecrated Temple property. That is to say, an item forbidden by a konam is like consecrated property. Just as with regard to consecrated property there is liability for misuse, so too with regard to konamot there is liability for misuse.

The Gemara comments on this. This dilemma is like a dispute between tanna’im. If one said: This loaf is konam to all like consecrated property, and he ate it, then, whether he ate it or whether another ate it, the one who ate it misused consecrated property. Therefore, since its status is that of consecrated property, it has the possibility of desanctification through redemption. If one said: This loaf is konam for me like consecrated property and he eats it, he misused consecrated property. If another eats it, he did not misuse consecrated property, as he said: To me. Therefore, it does not have the possibility of desanctification through redemption, since its status is not that of full-fledged consecrated property. This is the statement of Rabbi Meir.

And the Rabbis say: In the case of both vows taken in this manner and vows taken in that manner, no one misused consecrated property because there is no liability for misuse of consecrated objects in cases of konamot. Rabbi Meir disagrees and holds that there is liability for misuse in konamot.

Rav Aḥa, son of Rav Avya, said to Rav Ashi: If one said to another: My loaf is konam for you, and he then gave it to him as a gift, which of them misused consecrated property? If you say: Let the one who gives the loaf be liable for misuse, why would he be liable; the loaf is not forbidden to him? If you say: Let the one who receives the loaf be liable for misuse, he can say: I wanted to receive a permitted item; I did not want to receive a forbidden item. Since the loaf is forbidden, if I accepted it from you, it was not my intention to do so. Rav Ashi said to him: The one who receives the loaf is liable for misuse when he utilizes the loaf, as the principle with regard to misuse is that anyone who utilizes consecrated money for non-sacred purposes, when he is under the impression that it is non-sacred, misuses consecrated property. This person who received the loaf also misuses consecrated property.

Nedarim 35a explores how konam vows on property lose force once ownership transfers, and questions whether misuse laws for consecrated items apply to such vows.
