Mishnayos Nedarim Perek 4 Mishnah 1

The difference between one for whom benefit from another is forbidden by vow [hamuddar hana’a meḥaveiro] and one for whom benefit from his food is forbidden by vow concerns only setting foot on the other person’s property and borrowing from that person utensils that one does not use in preparation of food but for other purposes. Those two benefits are forbidden to the former but permitted to the latter. Therefore, with regard to one for whom benefit from another’s food is forbidden by vow, that person may not lend him utensils used in the preparation of food, e.g., a sieve, or a strainer, or a millstone, or an oven. However, he may lend him a garment, or a finger ring, or a cloak, or nose rings, as these are not used in the preparation of food. However, he may not lend them to one for whom benefit from him is forbidden by vow. And with regard to any item that one does not use in the preparation of food, in a place where one rents items of that kind, that item is forbidden. Meaning, one for whom benefit from another is forbidden by vow is prohibited from borrowing this type of item from the one who vowed and imposed the prohibition. This is because one can use the money saved by borrowing the item rather than renting it to purchase food.
