Yevamos 13:12 - 13:13

יגדלו זה עם זה – and he is not able to divorce her until he grows up, for the Jewish divorce bill of a minor is not a Jewish divorce bill.

היבמה שאמרה בתוך שלשים יום – that the levir took her in marriage, I have not had sexual relations with the levir and he states, “I had sexual relations with you,” and it is enough for you with a Jewish bill of divorce, they force him to perform Halitzah for she is believed that up to thirty days, we establish that a person sustains himself and doesn’t engage in sexual intercourse.

לאחר שלשים יום – he is believed that a person does not restrain himself without sexual intercourse for more than thirty days [after his marriage] (see Talmud Yevamot 111b). But, however, she is not permitted and considers herself a piece [of meat] and she is forbidden and requires Halitzah and we request of hi that he perform Halitzah but we don’t for him, for he stated that he had sexual intercourse [with her]. That we force him to perform Halitzah is within thirty days and we request of him to perform Halitzah after thirty days, and we don’t force him and we request that he perform levirate marriage. The Gemara (Tractate Yevamot 112a) establishes such as the example that the Jewish bill divorce leaves from under her hand, for since he gave the Jewish bill of divorce to his levirate relation, she was invalidated to him; but, however, she requires Halizah to make her permissible to the world. But if she herself said, “I had sexual intercourse [with him]” and he states that “I did not have sexual intercourse [with her],” we don’t suspect his words, and she does not require Halitzah.

הנודרת הנאה מיבמה בחיי בעלה כופין אותו שיחלוץ לה – she did not intend that her husband should die, and that she would fall before him (i.e., the levir) for levirate marriage, and she takes her Ketubah [settlement]. But, after the death of her husband, she rebels and we establish that we write a document stating the wife’s refusal of duties on the sister-in-law waiting for the levir to act and we requires of him to perform Halitzah and to give her Ketubah if he desires, but if he doesn’t want to perform Halitzah and she rebels against him, and she comes to lose her Ketubah [settlement], we force him to perform Halitzah.
