Kiddushin 4A

יציאה דכוותה קא ממעט.

it excludes a departure that is like it, i.e., a departure wherein the two masters are the potential recipients. Just as when no money is paid, the individual who might have received the payment is her master, so too, when money is paid, in a different set of circumstances, the money goes to the one who has authority over her, i.e., her father.

והא לא דמיא האי יציאה להאי יציאה, התם נפקא לה מרשות אדון לגמרי, והכא אכתי מיחסרא מסירה לחופה! בהפרת נדרים מיהא נפקא לה מרשותיה. דתנן: נערה המאורסה אביה ובעלה מפירין נדריה.

The Talmud asks: But this departure is not similar to that departure, as there, she leaves the authority of the master entirely upon being freed and she no longer retains any connection to him, and here, she still lacks the act of passing her over to the wedding canopy. Until she actually enters the wedding canopy, she has not left her father’s authority completely. The Talmud answers: Nevertheless, there is a similarity between her departures in both cases, as she leaves her father’s authority at least as far as the nullification of vows is concerned. As we learned in a Mishnah (Nedarim 66b): With regard to a betrothed young woman, her father and her husband together nullify her vows, and her father cannot nullify them alone.

והאי ״ויצאה חנם״ להכי הוא דאתא? הא מבעי ליה לכדתניא, דתניא: ״ויצאה חנם״⁠ – אלו ימי בגרות, ״אין כסף״⁠ – אלו ימי נערות.

The Talmud asks: But does this verse: “Then should she go out for nothing” (Exodus 21:11), come for that purpose, to teach that there is no money for this master, but there is money for a different master? But it is required for that which is taught in the following baraita. As it is taught in a baraita: The verse “Then should she go out for nothing, without money” should be understood as follows: “Then should she go out for nothing”; these words are referring to the days of adulthood, i.e., a Hebrew female slave leaves her owner’s authority once she becomes an adult. “Without money [ein kasef]”; these words are referring to the days of her youth, i.e., when she becomes a young woman she leaves his authority.
