Yevamot 112A

מיבזז בזיז מינה.

he is embarrassed with her. Therefore, it is possible that more time passed before he had sex with her.

עד שכופין אותו לחלוץ ⁠— ניכפנו לייבם! אמר רב: בשגיטה יוצא מתחת ידה.

§ The Talmud asks about the halakha that if he has not consummated the marriage, he is forced to perform ḥalitza: Before he is forced to perform ḥalitza, let us force him to consummate the levirate marriage. Rav said: The Mishnah is referring to a case where her bill of divorce is already to be found in her hand. The yavam has already given her a bill of divorce, but she claims that he never consummated the levirate marriage, and that therefore she is not released by the bill of divorce and still requires ḥalitza.

מיתיבי: יבמה שאמרה בתוך שלשים יום ״לא נבעלתי״⁠ — בין שהוא אומר ״בעלתי״, בין שהוא אומר ״לא בעלתי״, כופין אותו שיחלוץ לה. לאחר שלשים יום ⁠— מבקשין הימנו שיחלוץ לה.

The Talmud raises an objection: If, within 30 days, a yevama said: I have not had sex with him, then whether he says: I did have sex, or whether he says: I did not have sex, the court forces him to perform ḥalitza. If she made this claim after 30 days have passed, the court asks him to perform ḥalitza.

היא אומרת ״נבעלתי״, והוא אומר ״לא בעלתי״⁠ — הרי זה יוציא בגט. הוא אומר ״בעלתי״, והיא אומרת ״לא נבעלתי״⁠ — אף על פי שחזר ואמר ״לא בעלתי״, צריך גט וחליצה.

If she says after 30 days: I had sex with him, and he says: I did not have sex with her, then he releases her with a bill of divorce, because the legal presumption is that he did have sex with her. If he says: I had sex with her, and she says: I did not have sex with him, even if he retracted his statement and said: I did not have sex with her, this situation requires both a bill of divorce and ḥalitza. The fact that the baraita requires a bill of divorce indicates that the entire passage is referring to a case when she did not yet have a bill of divorce.
