Bava Kamma 80A

והטבח לוקח ושוחט, לוקח ושוהה ⁠– ובלבד שלא ישהה העגונה שבהן שלשים יום.

The baraita continues: And a butcher may buy small livestock and slaughter them, and again buy small livestock and keep them for a while, provided that he does not keep the last one of them that he bought beyond 30 days.

שאלו תלמידיו את רבן גמליאל: מהו לגדל? אמר להן: מותר. והתנן: אין מגדלין!

His students asked Rabban Gamliel: What is the halakha with regard to raising small livestock in Eretz Yisrael? Rabban Gamliel said to them: It is permitted. The Talmud interrupts its citation of the baraita to pose a question: How could Rabban Gamliel say this? But didn’t we learn in the Mishnah: One may not raise small livestock in Eretz Yisrael?

אלא הכי קא בעו מיניה: מהו לשהות? אמר להן: מותר, ובלבד שלא תצא ותרעה בעדר; אלא קושרה בכרעי המטה.

Rather, the text of the baraita must be emended, and they actually raised this dilemma before him: What is the halakha with regard to keeping them for a while? The Talmud resumes the quotation of the baraita: Rabban Gamliel said to them: It is permitted, provided that the animal does not go out and graze among the flock. Rather, one should tie it to the legs of the bed in his house.

תנו רבנן: מעשה בחסיד אחד שהיה גונח מלבו, ושאלו לרופאים, ואמרו: אין לו תקנה עד שינק חלב רותח משחרית לשחרית. והביאו לו עז וקשרו לו בכרעי המטה, והיה יונק ממנה משחרית לשחרית.

A baraita states: There was an incident involving a certain pious man who was groaning, i.e., suffering, due to a pain in his heart. Those caring for the man asked the physicians what to do for him, and they said: There is no other remedy for him but that he should suckle warm milk every morning. And they brought him a she-goat and tied it to the leg of the bed for him, and he would suckle milk from it every morning.
