Talmud for Beitzah 33:12

Rebbi Cahana the son of Rebbi Ḥiyya bar Abba said, on condition that he not act craftily¹⁴This does not refer to the discussion of the eruv tavshilin but to the statement in the Mishnah that a person without an eruv may cook more than his immediate needs are may keep the excess for the Sabbath. It is required that in that case the meal be cooked for an actual need of the holiday; when the quantities may be increased. One may not invent an imaginary need for this purpose. Babli 17b.. ¹⁵The following text is also in Ḥallah 1:9, Notes 215–217. The Mishnah follows Rebbi Simeon ben Eleazar as it was stated: “One does not make {food} on a holiday for use after the holiday.” Also, it was stated¹⁶Tosephta 2:5, Babli 17a.: “A woman may fill a pot with meat even if one eats only one piece from it, a kettle¹⁷Latin cocuma, -ae. with hot water even if one drinks only one cup from it. But baking, she should bake only what she needs.” For it is stated¹⁸Since neither the Mishnah nor R. Cahana in his interpretation of the Mishnah exclude baking bread from the general permission; it must follow R. Simeon ben Eleazar. Since the Mishnah is anonymous, it must be presumed to be teaching to be followed.: “Rebbi Simeon ben Eleazar says, a woman may fill the entire oven with bread because the bread turns out well if the oven is filled.¹⁶Tosephta 2:5, Babli 17a.” Rav Ḥuna preached following Rebbi Simeon ben Eleazar. Rebbi Joḥanan preached to the Tiberians following that of Rebbi Simeon ben Eleazar. He preached this as practice but they took it as to act on¹⁹In this context, “practice” means a valid opinion in the sense that anybody who follows it cannot be accused of acting illegally. “To act on” is the same as the expression “to instruct”, representing best practice, and one which should be recommended by the rabbi to anybody asking about such a situation.. Some wanted to say that he preached to act on. They came and asked him and he preached as practice, and they preached again but we do not know whether as practice or to act on. Rebbi Abba bar Zavdi said, Rebbi Abbahu instructed²⁰While we do not know R. Joḥanan’s exact position, the endorsements by Rav Ḥuna and R. Abbahu are enough to validate the opinion of R. Simeon ben Eleazar as practice to be recommended. Babli 17a. following Rebbi Simeon ben Eleazar.
