The Power of Jealousy

“jealousy is at the root of all human conflict,” Rabbi Alan Lew

(יד) לֹ֥א תַחְמֹ֖ד בֵּ֣ית רֵעֶ֑ךָ {ס} לֹֽא־תַחְמֹ֞ד אֵ֣שֶׁת רֵעֶ֗ךָ וְעַבְדּ֤וֹ וַאֲמָתוֹ֙ וְשׁוֹר֣וֹ וַחֲמֹר֔וֹ וְכֹ֖ל אֲשֶׁ֥ר לְרֵעֶֽךָ׃ {פ}
(14) You shall not covet your neighbor’s house: you shall not covet your neighbor’s wife, or his male or female slave, or his ox or his ass, or anything that is your neighbor’s.
(יז) אַל־יְקַנֵּ֣א לִ֭בְּךָ בַּחַטָּאִ֑ים כִּ֥י אִם־בְּיִרְאַת־יְ֝הֹוָ֗ה כׇּל־הַיּֽוֹם׃
(17) Do not envy sinners in your heart,
But only God-fearing men, at all times,
(א) וְשָׂרַי֙ אֵ֣שֶׁת אַבְרָ֔ם לֹ֥א יָלְדָ֖ה ל֑וֹ וְלָ֛הּ שִׁפְחָ֥ה מִצְרִ֖ית וּשְׁמָ֥הּ הָגָֽר׃ (ב) וַתֹּ֨אמֶר שָׂרַ֜י אֶל־אַבְרָ֗ם הִנֵּה־נָ֞א עֲצָרַ֤נִי יְהֹוָה֙ מִלֶּ֔דֶת בֹּא־נָא֙ אֶל־שִׁפְחָתִ֔י אוּלַ֥י אִבָּנֶ֖ה מִמֶּ֑נָּה וַיִּשְׁמַ֥ע אַבְרָ֖ם לְק֥וֹל שָׂרָֽי׃ (ג) וַתִּקַּ֞ח שָׂרַ֣י אֵֽשֶׁת־אַבְרָ֗ם אֶת־הָגָ֤ר הַמִּצְרִית֙ שִׁפְחָתָ֔הּ מִקֵּץ֙ עֶ֣שֶׂר שָׁנִ֔ים לְשֶׁ֥בֶת אַבְרָ֖ם בְּאֶ֣רֶץ כְּנָ֑עַן וַתִּתֵּ֥ן אֹתָ֛הּ לְאַבְרָ֥ם אִישָׁ֖הּ ל֥וֹ לְאִשָּֽׁה׃ (ד) וַיָּבֹ֥א אֶל־הָגָ֖ר וַתַּ֑הַר וַתֵּ֙רֶא֙ כִּ֣י הָרָ֔תָה וַתֵּקַ֥ל גְּבִרְתָּ֖הּ בְּעֵינֶֽיהָ׃ (ה) וַתֹּ֨אמֶר שָׂרַ֣י אֶל־אַבְרָם֮ חֲמָסִ֣י עָלֶ֒יךָ֒ אָנֹכִ֗י נָתַ֤תִּי שִׁפְחָתִי֙ בְּחֵיקֶ֔ךָ וַתֵּ֙רֶא֙ כִּ֣י הָרָ֔תָה וָאֵקַ֖ל בְּעֵינֶ֑יהָ יִשְׁפֹּ֥ט יְהֹוָ֖ה בֵּינִ֥י וּבֵינֶֽיׄךָ׃ (ו) וַיֹּ֨אמֶר אַבְרָ֜ם אֶל־שָׂרַ֗י הִנֵּ֤ה שִׁפְחָתֵךְ֙ בְּיָדֵ֔ךְ עֲשִׂי־לָ֖הּ הַטּ֣וֹב בְּעֵינָ֑יִךְ וַתְּעַנֶּ֣הָ שָׂרַ֔י וַתִּבְרַ֖ח מִפָּנֶֽיהָ׃
(1) Sarai, Abram’s wife, had borne him no children. She had an Egyptian maidservant whose name was Hagar. (2) And Sarai said to Abram, “Look, the LORD has kept me from bearing. Consort with my maid; perhaps I shall have a son through her.” And Abram heeded Sarai’s request. (3) So Sarai, Abram’s wife, took her maid, Hagar the Egyptian—after Abram had dwelt in the land of Canaan ten years—and gave her to her husband Abram as concubine. (4) He cohabited with Hagar and she conceived; and when she saw that she had conceived, her mistress was lowered in her esteem. (5) And Sarai said to Abram, “The wrong done me is your fault! I myself put my maid in your bosom; now that she sees that she is pregnant, I am lowered in her esteem. The LORD decide between you and me!” (6) Abram said to Sarai, “Your maid is in your hands. Deal with her as you think right.” Then Sarai treated her harshly, and she ran away from her.
(א) וַתֵּ֣רֶא רָחֵ֗ל כִּ֣י לֹ֤א יָֽלְדָה֙ לְיַעֲקֹ֔ב וַתְּקַנֵּ֥א רָחֵ֖ל בַּאֲחֹתָ֑הּ וַתֹּ֤אמֶר אֶֽל־יַעֲקֹב֙ הָֽבָה־לִּ֣י בָנִ֔ים וְאִם־אַ֖יִן מֵתָ֥ה אָנֹֽכִי׃
(1) When Rachel saw that she had borne Jacob no children, she became envious of her sister; and Rachel said to Jacob, “Give me children, or I shall die.”
(יד) כִּ֛י לֹ֥א תִֽשְׁתַּחֲוֶ֖ה לְאֵ֣ל אַחֵ֑ר כִּ֤י יְהֹוָה֙ קַנָּ֣א שְׁמ֔וֹ אֵ֥ל קַנָּ֖א הֽוּא׃
(14) for you must not worship any other god, because the LORD, whose name is Impassioned, is an impassioned God.
(יא) פִּֽינְחָ֨ס בֶּן־אֶלְעָזָ֜ר בֶּן־אַהֲרֹ֣ן הַכֹּהֵ֗ן הֵשִׁ֤יב אֶת־חֲמָתִי֙ מֵעַ֣ל בְּנֵֽי־יִשְׂרָאֵ֔ל בְּקַנְא֥וֹ אֶת־קִנְאָתִ֖י בְּתוֹכָ֑ם וְלֹא־כִלִּ֥יתִי אֶת־בְּנֵֽי־יִשְׂרָאֵ֖ל בְּקִנְאָתִֽי׃
(11) “Phinehas, son of Eleazar son of Aaron the priest, has turned back My wrath from the Israelites by displaying among them his passion for Me, so that I did not wipe out the Israelite people in My passion.

(כא) רַבִּי אֶלְעָזָר הַקַּפָּר אוֹמֵר, הַקִּנְאָה וְהַתַּאֲוָה וְהַכָּבוֹד, מוֹצִיאִין אֶת הָאָדָם מִן הָעוֹלָם:

(21) Rabbi Elazar Ha-kappar said: envy, lust and [the desire for] honor put a man out of the world.

אָמַר רֵישׁ לָקִישׁ מָה לְשׁוֹן קִינּוּי דָּבָר הַמֵּטִיל קִנְאָה בֵּינָהּ לְבֵין אֲחֵרִים אַלְמָא קָסָבַר קִינּוּי עַל פִּי עַצְמוֹ וְכוּלֵּי עָלְמָא לָא יָדְעִי דְּקַנִּי לַהּ וְאָמְרִי מַאי דְּקַמָּא דְּקָא בָּדְלָה וְאָתוּ לְמִיעְבַּד קִנְאָה בַּהֲדַהּ וְרַב יֵימַר בַּר רַבִּי שֶׁלֶמְיָא מִשְּׁמֵיהּ דְּאַבָּיֵי אָמַר דָּבָר הַמֵּטִיל קִנְאָה בֵּינוֹ לְבֵינָהּ אַלְמָא קָסָבַר קִינּוּי עַל פִּי שְׁנַיִם עֵדִים וְכוּלֵּי עָלְמָא יָדְעִי דְּקַנִּי לַהּ וְאִיהוּ הוּא דְּאָתֵי לְמִיעְבַּד קִנְאָה בַּהֲדַהּ אַלְמָא קָסָבְרִי דְּאָסוּר לְקַנּאוֹת וּמַאן דְּאָמַר מוּתָּר לְקַנּאוֹת מַהוּ לְשׁוֹן קִינּוּי אָמַר רַב נַחְמָן בַּר יִצְחָק אֵין קִינּוּי אֶלָּא לְשׁוֹן הַתְרָאָה וְכֵן הוּא אוֹמֵר וַיְקַנֵּא ה׳ לְאַרְצוֹ
§ Reish Lakish says: What is the meaning of the term: Warning [kinnui]? It means a matter that causes anger [kina] between her and others, as other men will not understand why she does not wish to be friendly with them any longer. The Gemara comments: Apparently, he holds that a warning is effective based on the husband’s own testimony, and therefore everyone else will not know that her husband issued a warning to her, and they will say: What is this matter happening before us that she separates herself from us, and they will come to act in anger with her. And Rav Yeimar bar Rabbi Shelemya says in the name of Abaye: The term kinnui means a matter that causes anger between him and her, i.e., between husband and wife. The Gemara comments: Apparently, he holds that a warning is effective based on the testimony of two witnesses. And since there are two witnesses, everyone knows that he issued a warning to her. Therefore, the warning does not cause anger between her and others. And the husband is he who will come to act in anger with her, as they will have mutual antagonism toward each other. Apparently, both Reish Lakish and Rav Yeimar bar Rabbi Shelemya hold that it is prohibited to issue a warning. Both are of the opinion that the word kinnui is a term for anger. Since causing anger is a negative trait, it follows that it is prohibited to issue a warning. The Gemara asks: And according to the one who says that it is permitted for him to issue a warning, what is the meaning of the term kinnui? Rav Naḥman bar Yitzḥak says: The term kinnui means nothing other than a term of forewarning, and so it says: “Then the Lord warned [vayekanneh] concerning His land and had pity for His people” (Joel 2:18). As detailed in that passage, the Lord ordered the locusts to stop destroying Eretz Yisrael.
וְאָמַר רָבָא הַאי מַקְרֵי יָנוֹקֵי דְּגָרֵיס וְאִיכָּא אַחֲרִינָא דְּגָרֵיס טְפֵי מִינֵּיהּ לָא מְסַלְּקִינַן לֵיהּ דִּלְמָא אָתֵי לְאִיתְרַשּׁוֹלֵי רַב דִּימִי מִנְּהַרְדְּעָא אָמַר כׇּל שֶׁכֵּן דְּגָרֵיס טְפֵי קִנְאַת סוֹפְרִים תַּרְבֶּה חָכְמָה
And Rava said: If there is a teacher of children who teaches a few subjects, and there is another who teaches more subjects than him, one does not remove the first teacher from his position to hire the second, as perhaps the other teacher will come to be negligent due to the lack of competition. Rav Dimi from Neharde’a said: On the contrary, all the more so is it the case that he will teach in a better manner if he knows that he is the sole instructor in the place, as jealousy among teachers increases wisdom. The one who was dismissed will try to refine his skills so that he will be rehired, and this will prevent negligence on the part of the other teacher.

(ז) רַבִּי נַחְמָן בַּר שְׁמוּאֵל בַּר נַחְמָן בְּשֵׁם רַב שְׁמוּאֵל בַּר נַחְמָן אָמַר, הִנֵּה טוֹב מְאֹד, זֶה יֵצֶר טוֹב. וְהִנֵּה טוֹב מְאֹד, זֶה יֵצֶר רָע. וְכִי יֵצֶר הָרָע טוֹב מְאֹד, אֶתְמְהָא. אֶלָּא שֶׁאִלּוּלֵי יֵצֶר הָרָע לֹא בָּנָה אָדָם בַּיִת, וְלֹא נָשָׂא אִשָּׁה, וְלֹא הוֹלִיד, וְלֹא נָשָׂא וְנָתַן. וְכֵן שְׁלֹמֹה אוֹמֵר (קהלת ד, ד): כִּי הִיא קִנְאַת אִישׁ מֵרֵעֵהוּ.

(7) Rabbi Nahman said in Rabbi Samuel's name: 'Behold, it was good' refers to the Good Desire; 'And behold, it was very good' refers to the Evil Desire. (It only says 'very good' after man was created with both the good and bad inclinations, in all other cases it only says 'and God saw that it was good') Can then the Evil Desire be very good? That would be extraordinary! But without the Evil Desire, however, no man would build a house, take a wife and beget children; and thus said Solomon: 'Again, I considered all labour and all excelling in work, that it is a man's rivalry with his neighbor.' (Ecclesiastes 4:4).

שָׁכַח וְאָכַל וְשָׁתָה אַל יִתְרָאֶה בִּפְנֵי הַצִּבּוּר וְאַל יַנְהִיג עִידּוּנִין בְּעַצְמוֹ שֶׁנֶּאֱמַר וַיֹּאמֶר יַעֲקֹב לְבָנָיו לָמָּה תִּתְרָאוּ אָמַר לָהֶם יַעֲקֹב לְבָנָיו אַל תַּרְאוּ עַצְמְכֶם כְּשֶׁאַתֶּם שְׂבֵעִין לֹא בִּפְנֵי עֵשָׂו וְלֹא בִּפְנֵי יִשְׁמָעֵאל כְּדֵי שֶׁלֹּא יִתְקַנְּאוּ בָּכֶם
With regard to one who forgot the fast and ate and drank, he should not show himself before the community while satiated, and he should not indulge in luxuries. One should not think that because one has already eaten, his fast is completely nullified, and one may conduct himself as if it were not a fast day at all. Rather, one should minimize one’s eating, as it is stated: “And Jacob said to his sons: Why do you show yourselves?” (Genesis 42:1). Jacob said to his sons: Do not show yourselves when you are satiated, not before the members of the house of Esau, nor before those of Ishmael, so that they not be jealous of you, as they suffer from hunger. This teaches that one should not show he is full when others are hungry.
