2,772. Paying Reuvein's Debts

Hilchos Nedarim 6:3

The only difference between one who vows not to benefit from another and one who vows not to derive benefit leading to food is crossing the other’s property and borrowing utensils that aren’t used in food preparation in a place where such things are borrowed rather than rented.

Hilchos Nedarim 6:4

If Reuvein was prohibited by a vow or an oath to benefit from Shimon, Shimon may pay the half-shekel in which Reuvein is obligated and he may pay Reuvein’s debts. The reason this is permitted is because Reuvein receives nothing, he just avoids having a claim filed against him, which is not prohibited as a form of benefit. Shimon may likewise supply food for Reuvein’s wife, his children, and his servants – even his non-Jewish servants; this is so even though Reuvein is obligated to feed his dependents. Shimon may not, however, supply food for Reuvein’s animal, regardless of whether it is of a kosher or non-kosher species. This is because it is a benefit to Reuvein if his animal gains weight.
