Shevuot 5B

דתנן: המוציא מרשות לרשות חייב. מי לא עסקינן דקא מעייל עיולי ⁠– וקא קרי ליה ״הוצאה״?

It is as we learned in a Mishnah (Shabbat 73a): One who carries out an item from one domain to another domain is liable. The Talmud claims: Are we not also dealing with a case where he is bringing it in from a public domain to a private domain, and nevertheless the Mishnah refers to it as carrying out?

ודלמא קא מפיק מרשות היחיד לרשות הרבים? אם כן, ניתני ״המוציא מרשות היחיד לרשות הרבים״; מאי ״מרשות לרשות״? דאפילו מרשות הרבים לרשות היחיד,

The Talmud questions this assertion: But perhaps the Mishnah is dealing with a case of carrying out an item from a private domain to a public domain. The Talmud defends its claim: If so, let it instead teach: One who carries out an item from a private domain to a public domain is liable. What is the reason it used the more generalized formulation: From one domain to another domain? To teach that one is liable even if one transfers an item from a public domain to a private domain.

וקא קרי לה ״הוצאה״. וטעמא מאי? תנא, כל עקירת חפץ ממקומו ⁠– ״הוצאה״ קרי לה.

The Talmud explains further: Even though the Mishnah addresses carrying an item in from a public domain to a private domain, it refers to it as carrying out. The Talmud explains: What is the reason for this? The tanna refers to any act that involves removal of an item from its place as carrying out. Accordingly, the term can appropriately be used even when an item is brought in to a private domain from a public domain.

אמר רבינא: מתניתין נמי דיקא, דקתני: ״יציאות שבת שתים שהן ארבע בפנים ושתים שהן ארבע בחוץ״, וקא מפרש הכנסה. שמע מינה.

Ravina said: The language of the Mishnah in tractate Shabbat is also precise in indicating this, as it teaches: With regard to acts of carrying out [yetziyyot] that are prohibited on Shabbat, there are primarily two basic actions that are 4 cases from the perspective of a person inside a private domain, and two basic actions that are 4 cases from the perspective of a person outside, in a public domain. And then, immediately, in the continuation of that Mishnah, it explicates the cases of bringing in an item. Conclude from it that the term: Carrying out, is also used to refer to bringing in an item.
