Nedarim 33A

והא מן מאכל נדר! אמר רבי שמעון בן לקיש: באומר ״הנאת מאכלך עלי״.

The Talmud asks: But didn’t he vow that he is prohibited from partaking of food, and those items are not food items? R' Shimon ben Lakish said: The Mishnah is referring to a case where he says: Benefit from your food is forbidden to me, which includes any benefit associated with food.

אימא שלא ילעוס חיטין ויתן על מכתו! אמר רבא: באומר ״הנאה המביאה לידי מאכלך עלי״.

The Talmud asks: Say that the result of a vow formulated in that manner is that he may not chew wheat kernels belonging to the one from whose food benefit is forbidden and place them on his wound, as that is a benefit that results from food. However, that vow does not render items used in the preparation of food forbidden. Rava said that the Mishnah is referring to a case where he says: Benefit that leads to preparation of your food is forbidden to me.

אמר רב פפא: שק להביא פירות, וחמור להביא עליו פירות, ואפילו צנא בעלמא, הנאה המביאה לידי מאכל הוא. בעי רב פפא: סוס לרכוב עליו וטבעת ליראות בה, מהו? מיפסק ומיזל בארעיה, מאי?

Rav Pappa said: Borrowing from him a sack in which to bring produce, or a donkey upon which to bring produce, or even merely a basket, each renders benefit that leads to food, and this benefit is forbidden. Rav Pappa raised a dilemma: If he seeks to borrow a horse upon which to ride or a ring with which to be seen when attending a feast, to create the impression that he is wealthy, what is the ruling? Is it prohibited to borrow these items, since having them in one’s possession may indirectly result in his being served before others or being served higher-quality food; and therefore, borrowing those items provides benefit that leads to food? With regard to traversing and walking on his land that facilitates one’s quick return home, enabling him to eat sooner, what is the halakha?
