What are the reasons that the rabbis decreed that cheese of non-Jews was forbidden for eating purposes, however one can benefit from them? The interaction in the mishna between Rabbi Yehoshua and Rabbi Yishmael regarding this issue is analyzed and is also brought as proof for the previous sugya about the difference between betrothing a woman with the dung of an ox who killed a person and the dung of an animal that was used for worshipping idols. Six possible explanations for the decree are brought by various amoraim. The next mishna discusses other decrees the rabbis instituted regarding items of non-Jews such as milk, bread, cooked items, oil, etc. Each item will be analyzed in the gemara.
