וְעָנְשׁ֨וּ אֹת֜וֹ מֵ֣אָה כֶ֗סֶף וְנָתְנוּ֙ לַאֲבִ֣י הַֽנַּעֲרָ֔ה כִּ֤י הוֹצִיא֙ שֵׁ֣ם רָ֔ע עַ֖ל בְּתוּלַ֣ת יִשְׂרָאֵ֑ל וְלֽוֹ־תִהְיֶ֣ה לְאִשָּׁ֔ה לֹא־יוּכַ֥ל לְשַּׁלְּחָ֖הּ כָּל־יָמָֽיו׃ (ס)
Mereka harus mendenda dia seratus syikal perak dan memberikannya kepada ayah gadis itu, karena ia telah mencemarkan nama baik seorang perawan Israel. Perempuan itu harus tetap menjadi istrinya; ia tidak boleh menceraikannya seumur hidupnya.
Mishneh Torah, Sheqel Dues
The silver denomination spoken about in the Torah regarding rape, seduction, one who puts out a bad name and one who kills a slave – that silver denomination is the shekel that is spoken about in every [other] place in the Torah. And its weight is three hundred and twenty barley seeds. And the Sages already added to it and made its weight [to be] like the weight of the coin called, [the] sela, at the time of the Second Temple. And how much is the weight of the sela? Three hundred eighty four medium barley grains.
Mishneh Torah, Virgin Maiden
The seduced woman who doesn't want to marry her seducer, or if her father did not want her to wed him, or if the seducer didn't want to enter [into marriage]- the seducer pays the [fifty sela'im] penalty and goes on his way and we don't force him to marry her. However if he does want to marry her, he doesn't pay a fine rather he writes her a ketubah like one would for any virgin maiden. However regarding the woman who was raped, if she or her father don't want her to marry her rapist they can decline collect the [fifty sela'im] penalty and go on their way. If she and her father want her to marry her rapist but the rapist doesn't want to marry her, we force him to marry her and he has to pay the penalty, as it states: "she shall be his wife" and this is a positive commandment. Even if she is lame, blind, or has leprosy he is forced to marry her and he cannot divorce her forever, as it is stated: "he shall never have the right to divorce her." This is a negative commandment.
Mishneh Torah, Virgin Maiden
Even though it says by a rapist: "he shall never have the right to divorce her" since [this negative commandment] is preceded by a positive commandment of: "she shall be his wife" this is a negative commandment that can be fixed by fulfilling the positive commandment. Thus, lashes are only administered if he does not fulfill the associated positive commandment like I will explain in The Laws of Sanhedrin. Therefore a rapist who sinned by divorcing his wife is forced to return to her and we don't give him lashes. However if his divorcée dies before he could remarry her, or she became betrothed to someone else, or if he was a Kohein who's forbidden from marrying a divorcée- he would get lashes since he violated a negative commandment and he is unable to fulfill the accompanying positive commandment.
