14הַשּׂוֹנֵא שֶׁנֶּאֱמַר בַּתּוֹרָה לֹא מֵאֻמּוֹת הָעוֹלָם הוּא אֶלָּא מִיִּשְׂרָאֵל. וְהֵיאַךְ יִהְיֶה לְיִשְׂרָאֵל שׂוֹנֵא מִיִּשְׂרָאֵל וְהַכָּתוּב אוֹמֵר (ויקרא יט יז) "לֹא תִשְׂנָא אֶת אָחִיךָ בִּלְבָבֶךָ". אָמְרוּ חֲכָמִים כְּגוֹן שֶׁרָאָהוּ לְבַדּוֹ שֶׁעָבַר עֲבֵרָה וְהִתְרָה בּוֹ וְלֹא חָזַר הֲרֵי זֶה מִצְוָה לְשָׂנְאוֹ עַד שֶׁיַּעֲשֶׂה תְּשׁוּבָה וְיָשׁוּב מֵרִשְׁעוֹ. וְאַף עַל פִּי שֶׁעֲדַיִן לֹא עָשָׂה תְּשׁוּבָה אִם מְצָאוֹ נִבְהָל בְּמַשָּׂאוֹ מִצְוָה לִטְעֹן וְלִפְרֹק עִמּוֹ וְלֹא יַנִּיחֶנּוּ נוֹטֶה לָמוּת שֶׁמָּא יִשְׁהֶה בִּשְׁבִיל מָמוֹנוֹ וְיָבוֹא לִידֵי סַכָּנָה. וְהַתּוֹרָה הִקְפִּידָה עַל נַפְשׁוֹת יִשְׂרָאֵל. בֵּין רְשָׁעִים בֵּין צַדִּיקִים. מֵאַחַר שֶׁהֵם נִלְוִים אֶל ה' וּמַאֲמִינִים בְּעִקַּר הַדָּת. שֶׁנֶּאֱמַר (יחזקאל לג יא) "אֱמֹר אֲלֵיהֶם חַי אָנִי נְאֻם ה' אֱלֹהִים אִם אֶחְפֹּץ בְּמוֹת הָרָשָׁע כִּי אִם בְּשׁוּב רָשָׁע מִדַּרְכּוֹ וְחָיָה".
The enemy mentioned in the Torah is not a gentile, but rather a Jew. One might ask: How is it possible for one Jew to hate another? Is it not written Leviticus 19:17: "Do not hate your brother in your heart"? Our Sages explained that this is referring to a person who while alone sees a colleague violate a transgression and rebukes him, but the colleague did not cease transgressing. In such an instance, it is a mitzvah to hate the person until he repents and abandons his wickedness. Even if he did not repent yet, if one sees him in panic because of his cargo, it is a mitzvah to unload and reload with him, instead of leaving him inclined toward death, lest he tarry because of his money and be brought to danger. For the Torah showed concern for the lives of the Jewish people, both the wicked and the righteous, for they are attached to G-d and believe in the fundamentals of our faith. And Ezekiel 33:11 states: "Say to them, 'As I live,' says G-d, the Lord, 'Do I desire the death of a wicked man? I desire that the wicked return from his path and live.' Blessed be G-d who grants assistance. With the help of the Almighty, the eleventh book has been completed. The number of chapters in this book are 62. Hilchot Nizkei Mammon has 14 chapters.
