Mishnayos Nedarim Perek 4 Mishnah 3

The mishna proceeds to list other tasks that one may perform for someone who is prohibited by vow from benefiting from him. And he separates his teruma and his tithes, provided that it is with the knowledge and consent of the owner of the produce. And he sacrifices for him the bird nests, i.e., pairs of birds, pigeons and turtledoves, of zavin (see Leviticus 15:13–15); the bird nests of zavot (see Leviticus 15:28–30); the bird nests of women after childbirth (see Leviticus 12:6–8); sin-offerings; and guilt-offerings. And he teaches him midrash, halakhot, and aggadot, but he may not teach him Bible. However, he may teach his sons and daughters Bible. And with regard to one for whom benefit from another is forbidden by vow, that other person may feed his wife and children, although the one who is bound by the vow is obligated in their support and benefits when another supports them. And he may not feed his animal, whether it is a kosher animal or whether it is a non-kosher animal. Rabbi Eliezer says: He may feed the non-kosher animal, and he may not feed the kosher animal. The Rabbis said to him: What is the difference between kosher and non-kosher animals in this respect? Rabbi Eliezer said to them: The kosher animal’s being belongs to Heaven, and the animal’s body is the property of its owner, as he can eat it. Therefore, the owner benefits directly when another feeds his animal. And a non-kosher animal, both its being and its body belong to Heaven, as it is prohibited for its owner to eat its meat. The Rabbis said to him: The non-kosher animal too, its being belongs to Heaven, and its body is the property of its owner, because if the owner chooses, he sells it to gentiles or feeds it to dogs.
