📜 Avodah Zarah — 13a

but it is permitted to cause benefit. Although by buying from the store one indirectly supports idol worship, as a portion of the sales are given to support idol worship, this is not prohibited by Torah law. And Rabbi Yoḥanan says: Even if the stores are adorned only with fruit one is also prohibited from buying from them. This is derived by an a fortiori inference: If it is prohibited to derive benefit from idol worship, is it not all the more so prohibited to cause benefit to idol worship? The Gemara raises an objection to Reish Lakish’s opinion from a baraita. Rabbi Natan says: On the day in which a reduction is made from the tax in honor of idol worship, they announce and say: Anyone who takes a wreath of roses and places it on his head and on the head of his donkey in honor of the object of idol worship, his tax will be reduced. And if one does not place a wreath on one’s head, his tax will not be reduced. What should a Jew who is present there do? If he places the wreath on his head and on the head of his donkey, he will be found to derive benefit from idol worship. And if he does not place the wreath on his head, he will be found to cause benefit to idol worship, through the tax that he pays. From here the Sages stated: One who conducts business in a market of idol worship will be forced either to benefit from or cause benefit to idol worship. Therefore, any animal he bought there should be destroyed, any produce, clothing or vessels should be left to decompose, and with regard to any money or metal vessels, which would not decompose on their own, one should take them and cast them into the Dead Sea. And what constitutes destroying the animal? One cuts off the hooves of the animal from the knee and below. The Gemara explains the objection to Reish Lakish’s statement. In any event, the baraita teaches that it is prohibited to cause benefit to idol worship, as it states: If he places the wreath on his head then he will be found to derive benefit from idol worship, and if he does not place the wreath on his head, he will be found to cause benefit to idol worship. How, then, can Reish Lakish claim that it is permitted to cause benefit to idol worship? Rav Mesharshiyya, son of Rav Idi, said: Rabbi Shimon ben Lakish holds as follows: The Rabbis disagree with Rabbi Natan, whose opinion is cited in the baraita, and I spoke in accordance with the opinion of the Rabbis who disagree with Rabbi Natan. The Gemara notes: And Rabbi Yoḥanan, who rules in accordance with the statement of Rabbi Natan, holds that the Rabbis do not disagree with Rabbi Natan; rather, everyone agrees that it is prohibited to cause benefit to idol worship. The Gemara asks: And is it so that they do not disagree? But isn’t it taught in a baraita: One may go to a fair of gentiles, whose purpose is to honor idol worship, and buy from the gentiles animals, and slaves, and maidservants, as the purchase raises the items to a more sanctified state; and he may buy houses, fields, and vineyards from them, due to the mitzva to settle Eretz Yisrael. And one may write the necessary deeds and confirm them in their gentile courts [be’arkaot], although this involves an acknowledgement of their authority, because it is as though he is rescuing his property from their hands, as the court’s confirmation and stamp of approval prevents the seller from denying the sale and claiming that the property still belongs to him. And if he is a priest, he may become ritually impure by going outside Eretz Yisrael, even though a priest is usually prohibited from leaving Eretz Yisrael to the impure land outside, in order to litigate with them and to contest their claims. And just as a priest may become ritually impure by going outside Eretz Yisrael, so may he become ritually impure for this purpose by entering a cemetery. The Gemara interrupts its citation of the baraita to express surprise at this last ruling: Can it enter your mind to say that a priest may become impure by entering a cemetery? The halakha that a cemetery imparts ritual impurity to a priest is by Torah law; how could the Sages override this prohibition? Rather, the baraita is referring to an area where there is uncertainty with regard to the location of a grave or a corpse [beit haperas], owing to the fact that a grave had been unwittingly plowed over, and the bones may have become scattered throughout the field. Such a field imparts ritual impurity by rabbinic law. The baraita continues: And a priest may likewise become ritually impure and leave Eretz Yisrael in order to study Torah or in order to marry a woman. Rabbi Yehuda says: When does this allowance apply? It applies when he cannot find a place to study in Eretz Yisrael. But when the priest can find a place to study in Eretz Yisrael, he may not become ritually impure by leaving the country. Rabbi Yosei says: Even when he can find a place to study Torah in Eretz Yisrael, he may leave the country and become ritually impure, because a person does not merit to learn from everyone, and it is possible that the more suitable teacher for him lives outside of Eretz Yisrael. Rabbi Yosei says, in support of his opinion: There was an incident involving Yosef the priest, who followed his teacher to the city of Sidon, outside of Eretz Yisrael, to learn Torah even though the preeminent Sage of his generation, Rabban Yoḥanan ben Zakkai, lived in Eretz Yisrael. And Rabbi Yoḥanan says about this: The halakha is in accordance with the opinion of Rabbi Yosei. The Gemara returns to the issue at hand. This baraita apparently indicates that the Rabbis do disagree with Rabbi Natan, as they hold that it is permitted to buy items from a gentile fair and cause benefit to idol worship, whereas the ruling of Rabbi Natan is a minority opinion. The Gemara responds: Rabbi Yoḥanan could have said to you: Actually, the Rabbis do not disagree with Rabbi Natan, and even according to this baraita one is prohibited from causing benefit for idol worship. The Gemara elaborates: And the fact that the baraita permits buying at a gentile fair is not difficult, as here, where Rabbi Natan prohibits buying items from a gentile fair, he states his ruling with regard to one who buys from a merchant, as a tax is taken from him for the benefit of idol worship; whereas there, in the baraita that permits buying items at the fair, it states its ruling with regard to one who buys from a homeowner, i.e., a private individual, where a tax is not taken from him. § The Gemara returns to discuss the baraita that cited the opinion of Rabbi Natan. The Master said above: Any animal that one bought there should be destroyed. The Gemara asks: But isn’t there a requirement to prevent suffering to animals? Abaye said: Although there is an enjoinder against causing suffering to a living creature, it is permitted when necessary, as the Merciful One states to Joshua: “You shall destroy their horses” (Joshua 11:6). The Master said above: And what constitutes destroying the animal? One cuts the hooves of the animal from the knee and below. The Gemara raises a contradiction from a baraita: One may neither consecrate objects, nor dedicate items for sacred use, nor valuate an item’s worth based on its appraisal (see Leviticus, chapter 27) and dedicate its monetary worth to the Temple treasury, in the present time, when the Temple no longer exists. And if one did consecrate, or dedicate, or valuate items for sacred use, the presence of these items might lead to the violation of the prohibition against using consecrated property. Therefore, if one dedicated an animal it should be destroyed. If he dedicated produce, garments, or vessels made from materials that decompose,
