כתנאי (ויקרא כב, כד) ומעוך וכתות ונתוק וכרות כולן בביצים דברי רבי יהודה
The Gemara comments that the first question with regard to castration of the testicles is like a dispute between tanna’im. It is stated with regard to animals that cannot be used as offerings due to blemishes: “That whose stones are bruised, or crushed, or torn, or cut you shall not sacrifice to the Lord” (Leviticus 22:24). All of these blemishes are referring to the animal’s testicles; this is the statement of Rabbi Yehuda.
בביצים ולא בגיד אלא כולן אף בביצים דברי רבי יהודה רבי אליעזר בן יעקב אומר כולם בגיד רבי יוסי אומר מעוך וכתות אף בביצים נתוק וכרות בגיד אין בביצים לא:
The Gemara asks: Could Rabbi Yehuda possibly mean that these blemishes apply only to the testicles and not to the penis? Certainly these should also be considered blemishes if they affect the penis, which is more exposed than the testicles. Rather, this is what the baraita is saying: All of these blemishes apply to the testicles also; this is the statement of Rabbi Yehuda. Rabbi Eliezer ben Ya’akov says: All of them apply only to the penis. Rabbi Yosei states the following distinction: “Bruised or crushed” applies to the testicles also. Conversely, when there are areas that are “broken or cut” on the penis, yes, these are considered a blemish, but on the testicles, no, they are not a blemish.
מתני׳ בהמה גסה נקנית במסירה והדקה בהגבהה דברי רבי מאיר ור' אליעזר וחכ"א בהמה דקה נקנית במשיכה:
MISHNA: A large domesticated animal is acquired by passing, when its current owner transfers it to a buyer by giving him the reins or the bit. And a small domesticated animal is acquired by lifting. This is the statement of Rabbi Meir and Rabbi Eliezer. And the Rabbis say: A small domesticated animal can be acquired by pulling also, and there is no need to lift it.
גמ׳ דרש רב בקימחוניא בהמה גסה נקנית במשיכה אשכחינהו שמואל לתלמידי דרב אמר להו מי אמר רב בהמה גסה נקנית במשיכה והאנן במסירה תנן ורב נמי במסירה אמר הדר ביה מההיא הוא דאמר כי האי תנא דתניא וחכ"א זו וזו נקנית במשיכה רבי שמעון אומר זו וזו בהגבהה
GEMARA: Rav taught in the town of Kimḥonya: A large domesticated animal is acquired by pulling. Shmuel found Rav’s students and said to them: Did Rav actually say that a large domesticated animal is acquired by pulling? But didn’t we learn in the mishna that it is acquired by passing? And several times I also heard Rav say that it is acquired by passing. Did he retract that ruling? Rav’s students replied: In fact, Rav retracted that ruling and he states his opinion in accordance with the opinion of that tanna, i.e., the Rabbis, as it is taught in a baraita: And the Rabbis say: Both small and large domesticated animals are acquired by pulling. Rabbi Shimon says: Both are acquired by lifting.
מתקיף לה רב יוסף אלא מעתה פיל לרבי שמעון במה יקנה אמר ליה אביי בחליפין אי נמי בשוכר את מקומו
Rav Yosef objects to this: If that is so, by what mode of acqui-sition can an elephant be acquired, according to the opinion of Rabbi Shimon? It is impossible to lift an elephant. Abaye said to him: It is possible to acquire it by the mode of acquisition of symbolic exchange, a legal act of acquisition formalizing the transfer of ownership of an article. Alternatively, one can acquire an elephant by renting its place temporarily and acquiring the elephant by means of the ground upon which it is standing.
רבי זירא אמר מביא ארבעה כלים ומניחן תחת רגליו שמעת מינה כליו של לוקח ברשות מוכר קנה לוקח הכא במאי עסקינן בסימטא
Rabbi Zeira says that there is another method: One brings four vessels and places them under the elephant’s feet, and he thereby acquires it like any other item that is inside the buyer’s vessels. The Gemara asks: Can you learn from Rabbi Zeira’s statement that if the buyer’s vessels, being used to acquire an item from the seller, are in the seller’s domain, the buyer acquires the item? The Gemara rejects this: This is no proof, as with what are we dealing here? The case in question is one where the vessels are not in the seller’s domain but in an alley [simta], which is neither a public nor a private domain. In a place of this kind the buyer’s vessels certainly effect acquisition for him.
