Nedarim 5:6-6:1

Nedarim 5:6

If one is prohibited by a vow from benefitting from his friend and he has no food, the friend can give some food to a third party as a gift, at which point the one who vowed may then eat it. There was once a person in a place called Beis Choron whose father was prohibited by a vow from benefitting from him. The son was making a wedding, so he gave the courtyard and the banquet as a gift to his friend on the condition that his father could come to the wedding and eat. The friend replied, “If they’re mine, then I consecrate them.” The son of the one who vowed said, “I didn’t give you my property so you could consecrate it!” The friend replied, “No, you gave it to me so that your father would come celebrate and you could make up with him, but you wanted to make me responsible for him circumventing his vow!” The Sages reviewed the matter and they ruled that in order to be considered a gift, it must be the property of the recipient to do with as he wishes, so that if he consecrates it, it is consecrated. Since that is not the case here, it does not qualify as a gift.

Nedarim 6:1

If a person vows, prohibiting himself from eating cooked foods, he may still eat roasted and overcooked foods. If he said, “Konam that I do not taste cooked food,” he may not eat something cooked in a sauce but he may eat thick foods. He is permitted to eat a soft-boiled egg and a gourd that was roasted in ashes. (The mishna here is discussing the intention of the word “tavshil.” While it translates as a “cooked food,” it has much narrower implications than the English equivalent.)
