Text Excerpt
ואי איתא, ליתני: עבר ואפה מותר! אמר רב אדא בר מתנה: תנא, תקנתא דהיתרא — קתני, תקנתא דאסורא — לא קתני.
And if it is so that if one baked without having placed an eiruv for the joining of cooked foods, it is permitted to eat the bread, let the baraita simply teach: With regard to one who transgressed the prohibition and baked, it is permitted to eat the bread. Rav Adda bar Mattana said: There is no proof from here, as the tanna is teaching a remedy involving acting in a permitted manner, and is not teaching a remedy involving a prohibited act. The tanna did not want to teach that it is also possible to solve the problem in this proscribed manner.
תא שמע: מי שהניח עירובי תבשילין — הרי זה אופה ומבשל ומטמין, ואם רצה לאכול את עירובו — הרשות בידו. אכלו עד שלא אפה עד שלא הטמין — הרי זה לא יאפה ולא יבשל ולא יטמין, לא לו ולא לאחרים. ולא אחרים אופין ומבשלין לו.
The Talmud suggests: Come and hear a resolution from a different baraita: One who prepared an eiruv for the joining of cooked foods on a Festival eve may bake and cook and insulate food on the Festival for Shabbat that occurs on the following day, and if he wants to eat his eiruv on Shabbat, he has permission to do so. But if he ate it on the Festival before he baked or before he insulated, he may neither bake, nor cook, nor insulate, neither for himself nor for others, and likewise others may neither bake nor cook for him.
אבל מבשל הוא ליום טוב, ואם הותיר — הותיר לשבת, ובלבד שלא יערים. ואם הערים — אסור!
However, even without an eiruv, one in this situation may cook for the Festival itself, and if he left over part of what he cooked, he has left it over for Shabbat, provided that he does not employ artifice to circumvent the prohibition by saying that he is cooking a large amount for guests on the Festival, when in fact he has Shabbat in mind. And if he employed artifice to circumvent the prohibition, it is prohibited to eat the food, by decree of the rabbis. This indicates that one who cooks on a Festival for Shabbat in a prohibited manner may not eat the food.
