Someone prohibited by a neder to benefit from another shall not lend him, nor shall he borrow from him; he shall not lend him money, nor shall he borrow money from him; he shall not sell to him, nor shall he buy from him.  He said to him: “Lend me your vow.” He responded: “It is not available.” He said: “Konam, my field with respect to ever plowing [it] with it.” If it was his practice to plow, he is forbidden, but other people are permitted; if it is not his practice to plow, he and all [other] people are forbidden.

[If] someone is prohibited by a neder to benefit from another, and he does not have what to eat, [the other person] goes to the storekeeper, and says: “So-and-so is prohibited by a neder to benefit from me, and I don't know what to do.” He gives him, and collects from this one.  [If] he had a house to be built, a fence to be erected, [or] a field to be harvested, [the other person] goes to the workers, and says: “So-and-so is prohibited by a neder to benefit from me, and I don't know what to do.” They may work for him, and collect wages from this one.

[If] they were traveling on the road, and he did not have what to eat, he gives [food] to someone else as a gift, and that one is permitted it. If there is no one else with them, he puts [it] on a rock or on a fence, and says: “These are free for whoever should want,” and that one takes and eats; R' Yose, however, forbids [this].

Partners who have prohibited with a neder the benefit of each other are forbidden to enter the yard. R' Eliezer ben Yaakov says: This one is entering into his own [property], and this one is entering into his own [property]; but both are forbidden to install a mill or an oven there, or to raise chickens.  [If] one of them was prohibited by a neder from benefiting from the other, he may not enter the yard. R' Eliezer ben Yaakov says: He may say to him: “I am entering my own [property]; I am not entering yours.” We force the one who made the neder to sell his share.
