וְאֶת־הַ֠חֲזִיר כִּֽי־מַפְרִ֨יס פַּרְסָ֥ה הוּא֙ וְלֹ֣א גֵרָ֔ה טָמֵ֥א ה֖וּא לָכֶ֑ם מִבְּשָׂרָם֙ לֹ֣א תֹאכֵ֔לוּ וּבְנִבְלָתָ֖ם לֹ֥א תִגָּֽעוּ׃ (ס)
Ni puerco: porque tiene uña hendida, mas no rumia, os será inmundo. la carne de éstos no comeréis, ni tocaréis sus cuerpos muertos.
Mishnah Nedarim
The only difference between one who is under a vow not to benefit at all from his neighbor, and one who is under a vow prohibiting food benefit, is in respect of walking [on his property] and [the use of] utensils not employed in the preparation of food. If a man is under a vow not to derive food benefit from his neighbor, he may not lend him a sifter, sieve, mill-stone or oven, but he may lend him a cloak, ring, garment, and earrings, and whatever is not employed in the preparation of food. In a place where things such as these are rented out, it is forbidden.
