13הָיְתָה מֵחַיָּבֵי מִיתַת בֵּית דִּין כְּגוֹן בִּתּוֹ וְאֵשֶׁת בְּנוֹ וְכַיּוֹצֵא בָּהֶן בֵּין הִתְרוּ בּוֹ בֵּין לֹא הִתְרוּ בּוֹ פָּטוּר מִן הַקְּנָס שֶׁנֶּאֱמַר (שמות כא כב) "וְלֹא יִהְיֶה אָסוֹן עָנוֹשׁ יֵעָנֵשׁ" הָא אִם הָיָה שָׁם אָסוֹן אֵין שָׁם עֹנֶשׁ. וְאַף עַל פִּי שֶׁהֲרִיגַת הָאִשָּׁה בִּשְׁגָגָה שֶׁהֲרֵי לֹא נִתְכַּוְּנוּ לָהּ שֶׁנֶּאֱמַר (שמות כא כב) "כִּי יִנָּצוּ אֲנָשִׁים וְנָגְפוּ אִשָּׁה" הָא לָמַדְתָּ שֶׁלֹּא חִלֵּק הַכָּתוּב בְּאָסוֹן בֵּין שׁוֹגֵג לְמֵזִיד לְפָטְרוֹ מִן הַתַּשְׁלוּמִין. וַהֲרֵי הוּא אוֹמֵר (ויקרא כד יח) "מַכֵּה נֶפֶשׁ בְּהֵמָה יְשַׁלְּמֶנָּה" (ויקרא כד כא) "וּמַכֵּה אָדָם יוּמָת" מָה מַכֵּה נֶפֶשׁ בְּהֵמָה לֹא חִלֵּק הַכָּתוּב בֵּין שׁוֹגֵג לְמֵזִיד לְחַיְּבוֹ בְּתַשְׁלוּמִין אַף מַכֵּה נֶפֶשׁ אָדָם לֹא חִלֵּק הַכָּתוּב בֵּין שׁוֹגֵג לְמֵזִיד לְפָטְרוֹ מִן הַתַּשְׁלוּמִין:
If the woman was forbidden to him due to a punishment of death by Beis Din, for example: his daughter, daughter-in-law, or similar- whether he was or wasn't warned he is exempt from paying the fine, as it states (Exodus 21:22): "If there will not be a [fatal] accident, he should be punished" the implication being that there was a fatal accident, no punishment would be administered. Even though this woman was killed unintentionally, the man didn't intend [to hurt] her as it is written [Ibid.]: "When men fight, and one of them pushes a woman" we learn from here that the Torah doesn't differentiate between an intentional and unintentional action to exempt him from a monetary obligation. And it says (Leviticus 24:18): "A person who fatally strikes an animal shall reimburse", and (Leviticus 24:21): "one who fatally strikes a person shall die." Just as by the killing of an animal the Torah didn't differentiate between an intentional and unintentional action regarding him be make him liable for payment, so too by the killing a person the Torah didn't differentiate between an intentional and unintentional to exempt him from payment.
