ופרומה משני צדדיה ורוחצת עם בני אדם
and with her garment open from both sides, and bathing with men, and ignores it.
עם בני אדם ס"ד אלא במקום שבני אדם רוחצין
The Gemara asks: Can it enter your mind that the baraita is referring to a wife who bathes with men? Even a man of the lowest moral character would not allow his wife to act in this manner. Rather, the baraita means that she bathes in a place where men often bathe.
זו מצוה מן התורה לגרשה שנאמר (דברים כד, א) כי מצא בה ערות וגו' ושלחה מביתו והלכה והיתה לאיש אחר הכתוב קראו אחר לומר שאין זה בן זוגו לראשון זה הוציא רשעה מביתו וזה הכניס רשעה לתוך ביתו
The baraita continues: With regard to this kind of wife, it is a mitzva by Torah law to divorce her, as it is stated: “Because he has found some unseemly matter in her, and he writes her a scroll of severance, and gives it in her hand, and he sends her out of his house…And she goes and becomes another [aḥer] man’s wife” (Deuteronomy 24:1–2). The verse called the second husband aḥer, other, to state that this man is not a peer of the first husband. They are morally distinct, as that first husband evicted a wicked woman from his house and this second man introduced a wicked woman into his house.
זכה שני שלחה שנאמר ושנאה האיש האחרון ואם לאו קוברתו שנאמר (דברים כד, ג) או כי ימות האיש האחרון כדאי הוא במיתה שזה הוציא רשעה מביתו וזה הכניס רשעה לתוך ביתו
If the second man merits, he will send her out, as it is stated in the following verse: “And the latter husband hates her…and he sends her out of his house” (Deuteronomy 24:3). And if not, she will bury him, as it is stated in the same verse: “Or if the latter husband dies.” It is appropriate for him to receive the punishment of death, as that first man evicted a wicked woman from his house and this second husband introduced a wicked woman into his house.
(מלאכי ב, טז) כי שנא שלח ר' יהודה אומר אם שנאתה שלח ר' יוחנן אומר שנאוי המשלח
§ The prophet Malachi states in rebuke of those who divorce their wives: “For I hate sending away, says the Lord, the God of Israel” (Malachi 2:16). Rabbi Yehuda says: The verse means that if you hate your wife, send her away. Do not continue living with a woman whom you hate. Rabbi Yoḥanan says: The verse means that one who sends his wife away is hated by God.
ולא פליגי הא בזוג ראשון הא בזוג שני
And the Gemara explains that they do not disagree. This statement is with regard to a first marriage, i.e., one should tolerate his first wife and not divorce her, and that statement is with regard to a second marriage, in which case the husband should divorce his wife if he hates her.
דאמר ר' אלעזר כל המגרש אשתו ראשונה אפילו מזבח מוריד עליו דמעות שנאמר (מלאכי ב, יג) וזאת שנית תעשו כסות דמעה את מזבח ה' בכי ואנקה מאין [עוד] פנות אל המנחה ולקחת רצון מידכם ואמרתם על מה על כי ה' העיד בינך ובין אשת נעוריך אשר אתה בגדתה בה והיא חברתך ואשת בריתך:
As Rabbi Elazar says: With regard to anyone who divorces his first wife, even the altar sheds tears over him, as it is stated: “And this further you do: You cover the altar of the Lord with tears, with weeping, and with sighing, insomuch that He does not regard the offering anymore, nor does He receive it with goodwill from your hand. Yet you say: What for? Because the Lord has been witness between you and the wife of your youth, against whom you have dealt treacherously, though she is your companion, and the wife of your covenant” (Malachi 2:13–14). Clearly one should not divorce the wife of his youth, i.e., his first wife, as one who does so is hated by God for divorcing the woman to whom he was bound in companionship and covenant.
