ONE WHO WAS PERMITTED TO LEAVE (Yerushalmi Perek 4 Halachah 3 Daf 28a)

מתני' מי שיצא ברשות אמרו לו כבר נעשה מעשה יש לו אלפיים אמה לכל רוח

(a)

(Mishnah): If one was permitted to leave the Techum (e.g. to testify about the new moon or to save lives) and he found out that the Mitzvah was already done, he has 2000 Amos [from where he was when he found out] in every direction;

אם היה בתוך התחום כאילו לא יצא

(b)

If he was still inside the Techum, it is as if he never left.

שכל היוצאין להציל חוזרין למקומן:

(c)

Anyone who leaves the Techum to save may return to his place.

גמ' דל כן מה אנן אמרין.

(d)

(Gemara) Question: (Since he was permitted to leave, obviously he has 2000 Amos!) If [our Mishnah] did not this teach this, what would we say?

יעשה כמי שיצא באונס ולא יהיה לו אלא ארבע אמות לפום כן צריך מימר יש לו אלפיים אמה לכל רוח

(e)

Answer: He should be like one who left b'Ones, and he has only four Amos. Therefore, our Mishnah needs to teach that he has 2000 Amos in every direction.

אמר רב חונה והן שיהו ד' אמות אוכלות מתחום טבריא ומתחום מגדלה

(f)

(R. Chunah): (If he was still inside the Techum, it is as if he never left.) This is if four Amos of the Techum of Tiverya overlap the Techum of Magdelah (e.g. if he went from Tiverya to Magdelah).

רבי חונה בשם רב אדא בר אחווה רבי לא בשם ר"ש בן לקיש ואפילו יצא למגדלה וחזר כאילו לא יצא.

(g)

(R. Chunah citing Rav Ada bar Achavah and R. La citing Reish Lakish): Even if he went [out of his Techum] to Magdelah (e.g. the Techumim meet without any overlap), and returned, it is as if he did not leave.

רבי יישוע דרומייה בעי עד כדון בשיצא שוגג ואפילו יצא מזיד

(h)

Question (R. Yeshua of the south): Is this [Heter to return] only for one who left b'Shogeg - or is it even if he left b'Mezid [without a Heter, and a need arose and he saved]?

א"ר פנחס מתניתא אמרה כן שכל היוצאין להציל חוזרין למקומן

(i)

Answer (R. Pinchas - Mishnah): Anyone who leaves the Techum to save may return to his place. (This comes to include one who left without intent to save!)

חוזרין אפילו בזיינן:

(j)

Rejection: [The inclusion teaches that] they may return even with their weapons.
