The entire mishna is in accordance with the opinion of Rabbi Tarfon; the first part of the latter clause is stated with regard to a jointly owned courtyard, which under the terms of their partnership is designated for the use of one of them, i.e., the injured party, to keep his produce there, and for this one and for that one to keep their oxen there. Accordingly, with regard to damage of the category of Eating caused by one partner’s ox to the injured party’s produce in that courtyard, it is equivalent to the case of a courtyard owned exclusively by the injured party, and the ox’s owner is liable for all the damage. But with regard to damage of the category of Goring, since they are both allowed to keep oxen there, the courtyard is equivalent to a public domain, and if one’s innocuous ox causes damage there, one is liable for only half the cost of the damage.

Rav Kahana said: I stated this teaching of Rabbi Elazar before Rav Zevid of Neharde’a, and he said to me: Are you really able to interpret that the entire mishna is in accordance with the opinion of Rabbi Tarfon? But doesn’t the mishna teach: Concerning acts of damage performed with the tooth, the animal is considered forewarned with regard to eating that which is fitting for it to eat. This indicates that only if what it eats is fitting for it, then yes, one is liable for the full cost of the damage, but if it eats something that is not fitting for it, the owner would not be liable for the full cost of the damage, but only for half the cost of the damage.

Rav Kahana explains his difficulty: And if the mishna is in accordance with the opinion of Rabbi Tarfon, the owner should be liable to pay the full cost of the damage even if his animal ate something not fitting for it, as doesn’t Rabbi Tarfon say: The halakha of cases of Goring performed by an innocuous animal, which is atypical, done in the courtyard of the injured party, is that the owner of the ox pays the full cost of the damage even if the ox is innocuous.

Rather, Rav Kahana said: Actually it must be that the entire mishna is in accordance with the opinion of the Rabbis and the mishna is incomplete and this is what it is teaching: The opening clause should be understood as saying: There are five damage-causing acts that animals can perform twice and remain innocuous, but if they were warned for performing those acts three times, with regard to the five acts they are considered forewarned, i.e., the mishna is not referring to two different sets of damages, five acts for which the animal is considered innocuous and five for which it is considered forewarned. Rather, both statements in the initial clause of the mishna are referring to the same five acts of Goring, and they teach that although the animal is initially considered innocuous with regard to these five acts, it can become forewarned.

The next part of the mishna then provides another halakha: But for damage of the categories of Eating and Trampling, an animal is considered forewarned from the outset. The next two items in the mishna: A forewarned ox and an ox that causes damage on the property of the injured party, should be understood as a question and an answer: And where does their forewarned status with regard to these acts apply? It applies in the courtyard of the injured party. According to Rav Kahana’s explanation, the statement: In the courtyard of the injured party, refers only to cases of Eating or Trampling, not to acts classified as Goring, and therefore it is true even according to the opinion of the Rabbis.

Ravina objects to this explanation: Doesn’t the mishna below (24b) teach: With regard to the case of an ox that causes damage to the property of the injured party on the property of the injured party, stated in the mishna here (15b), how so, i.e., what are the circumstances in which one is liable to pay the full cost of the damage? The mishna below (24b) proceeds to list acts of damage classified as Goring. Ravina states his objection: Granted, if you say that the mishna here (15b) discusses that case, i.e., that it is referring to Goring, it is due to that ruling that the mishna below teaches: How so, and proceeds to discuss one’s liability for Goring, as it is elucidating the case mentioned in the mishna here. But if you say, as Rav Zevid suggests, that the mishna here (15b) does not discuss Goring, what is the meaning of the mishna below when it asks: How so, and then proceeds to discuss one’s liability for Goring?

Rather, Ravina said: The mishna is incomplete and this is what it is teaching: There are five damage-causing acts that animals can perform twice and remain innocuous, but if they were warned for performing those acts three times with regard to the five acts, they are considered forewarned.

The next part of the mishna then provides another halakha: But for damage of the categories of Eating and Trampling, an animal is considered forewarned from the outset, and this is a case in which all agree that the animal is classified as a forewarned ox. And there is the case of an ox that causes damage to the property of the injured party, on the property of the injured party, which is subject to a dispute between Rabbi Tarfon and the Rabbis. And there are other cases similar to these in which animals are considered forewarned from the outset, namely: The wolf, the lion, the bear, the leopard, the bardelas, and the snake.

The Gemara notes: This interpretation of the mishna is also taught in a baraita: There are five damage-causing acts that animals can perform twice and remain innocuous, but if they were warned for performing those acts three times with regard to the five acts, they are considered forewarned. The next part of the mishna then provides another halakha: But for damage of the categories of Eating and Trampling, an animal is considered forewarned from the outset, and this is a case in which all agree that the animal is classified as a forewarned ox. And there is the case of an ox that causes damage to the property of the injured party, on the property of the injured party, which is subject to a dispute between Rabbi Tarfon and the Rabbis. And there are other cases similar to these in which animals are considered forewarned from the outset, namely: The wolf, the lion, the bear, the leopard, the bardelas, and the snake.

There are those who raise this issue as a contradiction and through doing so arrived at the same conclusions, as follows: We learned in the opening clause of the mishna: There are five damage-causing acts that animals can perform twice and remain innocuous, and there are five damage-causing acts for which an animal is considered forewarned. With regard to this, one can ask: But is there nothing else? But aren’t there the cases mentioned in the continuation of the mishna: The wolf, the lion, the bear, the leopard, the bardelas, and the snake? These are considered to be forewarned even if they had never caused damage before.

And they resolve the contradiction through that which Ravina said: The mishna is incomplete and this is what it is teaching: There are five damage-causing acts that animals can perform twice and remain innocuous, but if they were warned for performing those acts three times with regard to the five acts, they are considered forewarned. The next part of the mishna then provides another halakha: But for damage of the categories of Eating and Trampling, an animal is considered forewarned from the outset, and this is a case in which all agree that the animal is classified as a forewarned ox. And there is the case of an ox that causes damage to the property of the injured party, on the property of the injured party, which is subject to a dispute between Rabbi Tarfon and the Rabbis. And there are other cases similar to these in which animals are considered forewarned from the outset, namely: The wolf, the lion, the bear, the leopard, the bardelas, and the snake.

§ The mishna teaches: An animal is not considered forewarned with regard to Goring, i.e., not for goring with its horns, nor for pushing with its body, nor for biting, nor for crouching upon items in order to damage them. Rabbi Elazar says: They taught this only with regard to large vessels, as it is atypical for an animal to crouch upon them, and therefore the act is classified as a subcategory of Goring. But if the animal crouched upon small vessels, since that is its typical manner of behavior, it is classified as a subcategory of Trampling, for which the animal is considered forewarned from the outset.

The Gemara suggests: Let us say that the following baraita supports the opinion of Rabbi Elazar: An animal is considered forewarned, from the outset, to walk in its typical manner and to break or crush a person, or an animal, or vessels. The baraita indicates that an animal’s typical manner is to crush vessels, presumably by crouching down upon them. This would seem to contradict the mishna that states that such behavior is atypical. It would appear the only resolution to this contradiction is if one accepts the distinction made by Rabbi Elazar that the mishna concerns large vessels and the baraita concerns small vessels.

The Gemara rejects this: Perhaps the baraita concerns a case where the animal pushed against the utensils from the side and crushed them against a wall, but it does not concern a case where it crouched upon them.

There are those who say a different version of this discussion, as follows: Rabbi Elazar says: Do not say that the mishna’s ruling refers only to large vessels, as it is atypical for an animal to crouch upon them, but if the animal crouched upon small vessels, that is its typical manner and for that type of damage the animal is considered forewarned. Rather, the mishna refers even to small vessels, as it is atypical for an animal to crouch upon them.

The Gemara raises an objection from a baraita: An animal is considered forewarned, from the outset, to walk in its typical manner and to break or crush a person, or an animal, or vessels.

Rabbi Elazar said: Perhaps the baraita concerns only a case where the animal pushed against the utensils from the side and crushed them against a wall.

There are those who raise this issue as a contradiction: We learned in the mishna: An animal is not considered forewarned with regard to Goring, i.e., not for goring with its horns, nor for pushing with its body, nor for biting, nor for crouching upon items in order to damage them. But isn’t it taught in a baraita: An animal is considered forewarned, from the outset, to walk in its typical manner and to break or crush a person, or an animal, or vessels? In order to resolve this contradiction, Rabbi Elazar said: It is not difficult; here, in the mishna, the reference is to large vessels, while there, in the baraita, the reference is to small vessels.

§ The mishna teaches: The wolf, the lion, the bear, the leopard, the bardelas, and the snake; these are considered to be forewarned even if they had never caused damage before. The Gemara asks: What is a bardelas? Rav Yehuda said: It is a nafreza. The Gemara asks: What is a nafreza? Rav Yosef said: It is an appa.

The Gemara raises an objection from a baraita: In addition to the list of animals that are considered forewarned, Rabbi Meir says: Also the hyena [tzavo’a]. Rabbi Elazar says: Also the snake. And Rav Yosef said in explanation of the baraita: The hyena mentioned by Rabbi Meir, this is the animal called an appa. If Rav Yosef understands a hyena to be an appa, how could he also claim, above, that it is a bardelas?

The Gemara explains: It is not difficult: Here, in the baraita, Rabbi Meir is referring to a male hyena, and there, in the mishna, the reference is to a female hyena.

And it is apparent that a male hyena is distinct from a female one, as it is taught in a baraita: A male hyena after seven years metamorphoses into an insectivorous bat [atalef ]; an insectivorous bat after seven years metamorphoses into a herbivorous bat [arpad]; a herbivorous bat after seven years metamorphoses into a thistle [kimosh]; a thistle after seven years metamorphoses into a briar [ḥo’aḥ]; and a briar after seven years metamorphoses into a demon. Similarly, a person’s spine, seven years after his death, metamorphoses into a snake. The Gemara qualifies the last statement: And this matter applies only to a case where that person did not bow during the blessing of thanksgiving, the eighteenth blessing of the Amida prayer.

The Gemara analyzes the baraita: The Master says above: In addition to the list of animals that are considered forewarned, Rabbi Meir says: Also the hyena.
