42 Nedarim 5/5-6 & 6/1

(5) And what is [considered publicly available] to the people who ascended from Babylon? For example, the Temple Mount, and the [temple] courtyards, and the [water] hole in the middle of the road. And what is [considered] to be owned by the city itself? For example, the town square, the [public] bathhouse, the synagogue, the ark [where the Torah is kept] and the sefarim [books of the Tanach written in holiness, on parchment, and used for personal or public study, or for reading aloud in public. Sometimes the intent is specifically Torah scrolls], and [property of] one who writes over his share [of the public property in the city] to the Nasi [head of the Jewish community in the Land of Israel]. Rabbi Yehuda says: [it is the same,] whether one writes over [his property] to the Nasi, or whether he writes it over to a common citizen. What, then, is [the difference] between writing over to the Nasi and writing over to a common citizen? That one who writes over to the Nasi doesn't need to do any action which enables the transaction. But the Sages say: whether one does this [wrote over to the Nasi] or this [wrote over to a common citizen], one needs to do an action which enables the transaction, and they only referred to a Nasi [here] because that was the case [then, at the time when this was discussed]. Rabbi Yehuda says: People of the Galilee don't need to write over [their property to anyone], since their predecessors wrote it over for them.

(6) If one vows not to derive any benefit from one's friend, but [the friend] has nothing to eat - he may give [food] to a third party [as a gift], and [the friend] is permitted [to take it]. It once happened in Beit Horon that someone's father was forbidden [by vow] to benefit from him. [Now, the son] was marrying off his [own] son, and said to his friend: "May the courtyard and the festive meal be a gift unto you, on the condition that my father come and celebrate with us at the festive meal." "If it is truly mine," he said, "then let it all be consecrated unto Heaven." [The son] said to [his friend]: "I didn't give my property to you for you to consecrate it unto Heaven!" He replied: "You gave it to me so that you and your father can feast together, and be reconciled, while the transgression of breaking the vow will fall upon [me]!" When the case was presented to the Sages, they ruled: any gift not given in a manner allowing for consecration is not a gift at all.

(1) One who vows not to eat cooked foods, it is permissible for them to eat of roasted foods, and seethed foods. If he says: "Konam that I taste any cooked food," he cannot eat anything soupy cooked in a pot, but is allowed to eat solid foods, and he may eat a soft-boiled egg and the gourd baked in hot ashes.
