Jewish sources from Scripture to Talmud address anger as a destructive character trait and spiritual danger. The teachings emphasize both the practical harms of anger—poor judgment, conflict, and sin—and its deeper spiritual consequences, including the loss of wisdom and divine connection.
אַל תְּהִי נוֹחַ לִכְעֹס
Opens as a working sheet — explore, annotate, and export.
Proverbs 14:17
The verse states that 'one who is quick to anger acts foolishly,' directly linking anger to poor judgment and foolish behavior.
קְֽצַר־אַ֭פַּיִם יַעֲשֶׂ֣ה אִוֶּ֑לֶת וְאִ֥ישׁ מְ֝זִמּ֗וֹת יִשָּׂנֵֽא׃
A hothead commits folly; A man of intrigues will be hated.
Why it matters — A foundational biblical statement on the destructive nature of anger and its connection to foolishness.
Psalms 37:8
'Cease from anger and forsake wrath; do not fret — it leads only to evil.' The Psalmist counsels complete abandonment of anger as a spiritual discipline.
הֶ֣רֶף מֵ֭אַף וַעֲזֹ֣ב חֵמָ֑ה אַל־תִּ֝תְחַ֗ר אַךְ־לְהָרֵֽעַ׃
ה Give up anger, abandon fury, do not be vexed; it can only do harm.
Why it matters — A direct biblical call to forsake anger, showing it as spiritually dangerous.
Proverbs 29:22
'A man of wrath stirs up strife, and one given to anger causes much transgression' — anger is linked to both interpersonal conflict and sin.
אִֽישׁ־אַ֭ף יְגָרֶ֣ה מָד֑וֹן וּבַ֖עַל חֵמָ֣ה רַב־פָּֽשַׁע׃
An angry man provokes a quarrel; A hothead commits many offenses.
Why it matters — Directly associates anger with transgression and conflict, key themes in the Torah's treatment of anger.
Shabbat 105b
Resh Lakish teaches that one who tears his clothes, breaks his vessels, or scatters his money in anger should be considered as one who worships idols, for such is the craft of the evil inclination.
אֵימַר דְּשָׁמְעַתְּ לֵיהּ לְרַבִּי יְהוּדָה בִּמְתַקֵּן, בִּמְקַלְקֵל מִי שָׁמְעַתְּ לֵיהּ? אָמַר רַבִּי אָבִין: הַאי נָמֵי מְתַקַּן הוּא, דְּקָעָבֵיד נַחַת רוּחַ לְיִצְרוֹ. וּכְהַאי גַּוְונָא מִי שְׁרֵי? וְהָתַנְיָא, רַבִּי שִׁמְעוֹן בֶּן אֶלְעָזָר אוֹמֵר מִשּׁוּם חִילְפָא בַּר אַגְרָא שֶׁאָמַר מִשּׁוּם רַבִּי יוֹחָנָן בֶּן נוּרִי: הַמְקָרֵע בְּגָדָיו בַּחֲמָתוֹ, וְהַמְשַׁבֵּר כֵּלָיו בַּחֲמָתוֹ, וְהַמְפַזֵּר מְעוֹתָיו בַּחֲמָתוֹ, יְהֵא בְּעֵינֶיךָ כְּעוֹבֵד עֲבוֹדָה זָרָה. שֶׁכָּךְ אוּמָּנוּתוֹ שֶׁל יֵצֶר הָרָע: הַיּוֹם אוֹמֵר לוֹ עֲשֵׂה כָּךְ, וּלְמָחָר אוֹמֵר לוֹ עֲשֵׂה כָּךְ, עַד שֶׁאוֹמֵר לוֹ עֲבוֹד עֲבוֹדָה זָרָה וְהוֹלֵךְ וְעוֹבֵד. אָמַר רַבִּי אָבִין: מַאי קְרָאָה — ״לֹא יִהְיֶה בְךָ אֵל זָר וְלֹא תִשְׁתַּחֲוֶה לְאֵל נֵכָר״, אֵיזֶהוּ אֵל זָר שֶׁיֵּשׁ בְּגוּפוֹ שֶׁל אָדָם? הֱוֵי אוֹמֵר, זֶה יֵצֶר הָרָע.
The Gemara asks: Say that you heard that Rabbi Yehuda rules that one is liable for performing a labor not needed for its own sake in the case of a constructive act; did you hear him deem one liable in the case of a destructive act? Rabbi Avin said: This case, where one rends his garment in anger, is also constructive, because in doing so he assuages his anger. Rending his garment calms him; therefore, it can be said that he derives benefit from the act of rending, and it is consequently a constructive act. The Gemara asks: And is it at all permitted to tear in that manner? Wasn’t it taught in a baraita that Rabbi Shimon ben Elazar says in the name of Ḥilfa bar Agra, who said in the name of Rabbi Yoḥanan ben Nuri: One who rends his garments in his anger, or who breaks his vessels in his anger, or who scatters his money in his anger, should be like an idol worshipper in your eyes, as that is the craft of the evil inclination. Today it tells him do this, and tomorrow it tells him do that, until eventually, when he no longer controls himself, it tells him worship idols and he goes and worships idols. Rabbi Avin said: What verse alludes to this? “There shall not be a strange god within you, and you shall not bow to a foreign god” (Psalms 81:10). What is the strange god that is within a person’s body? Say that it is the evil inclination. One may not rend his garments in anger, because in doing so he is deriving pleasure from satisfying the evil inclination.
Why it matters — One of the most striking Talmudic statements on anger, equating it with idolatry in severity.
Pirkei Avot 2:10
Rabbi Eliezer advises 'Do not be easily angered' (al tihei kapdanim) as one of the core pieces of practical ethical guidance for a person's conduct.
רַבִּי אֱלִיעֶזֶר אוֹמֵר, יְהִי כְבוֹד חֲבֵרְךָ חָבִיב עָלֶיךָ כְּשֶׁלָּךְ, וְאַל תְּהִי נוֹחַ לִכְעֹס.
They [each] said three things: Rabbi Eliezer said: Let the honor of your friend be as dear to you as your own; And be not easily provoked to anger; And repent one day before your death.
Why it matters — Direct mishnaic guidance against anger as part of the ethical path.
Nedarim 22a
The Talmud lists severe consequences of anger: a wise person loses their wisdom, a prophet loses their prophecy, and one who loses their temper — even the Divine Presence departs from them.
אָמַר רַבִּי שְׁמוּאֵל בַּר נַחְמָנִי אָמַר רַבִּי יוֹנָתָן: כׇּל הַכּוֹעֵס כׇּל מִינֵי גֵיהִנָּם שׁוֹלְטִין בּוֹ, שֶׁנֶּאֱמַר: ״וְהָסֵר כַּעַס מִלִּבֶּךָ וְהַעֲבֵר רָעָה מִבְּשָׂרֶךָ״, וְאֵין ״רָעָה״ אֶלָּא גֵּיהִנָּם, שֶׁנֶּאֱמַר: ״כֹּל פָּעַל ה׳ לַמַּעֲנֵהוּ וְגַם רָשָׁע לְיוֹם רָעָה״. וְלֹא עוֹד אֶלָּא שֶׁהַתַּחְתּוֹנִיּוֹת שׁוֹלְטוֹת בּוֹ, שֶׁנֶּאֱמַר: ״וְנָתַן ה׳ לְךָ שָׁם לֵב רַגָּז וְכִלְיוֹן עֵינַיִם וְדַאֲבוֹן נָפֶשׁ״, אֵיזֶהוּ דָּבָר שֶׁמְּכַלֶּה אֶת הָעֵינַיִם וּמַדְאִיב אֶת הַנֶּפֶשׁ — הֱוֵי אוֹמֵר: אֵלּוּ הַתַּחְתּוֹנִיּוֹת.
§ Apropos the verse “There the wicked cease from troubling,” the Gemara cites a related statement: Rabbi Shmuel bar Naḥmani said that Rabbi Yonatan said: Anyone who gets angry, all kinds of Gehenna rule over him, because anger causes him to transgress all kinds of severe sins, as it is stated: “Therefore remove vexation from your heart and put away evil from your flesh” (Ecclesiastes 11:10), and the evil mentioned is nothing other than Gehenna, as it is stated: “The Lord has made everything for His own purpose and even the wicked for the day of evil” (Proverbs 16:4), which is interpreted to mean that ultimately the day of the evildoer in Gehenna will arrive. And not only that, but also hemorrhoids will control him, as it is stated: “But the Lord shall give you there a trembling heart, and failing of eyes, and languishing of soul” (Deuteronomy 28:65). Which is the matter of sickness that causes failing of the eyes in pain and causes languishing of the soul? You must say this is referring to hemorrhoids.
Why it matters — Illustrates the spiritual and intellectual damage caused by anger according to the Sages.
Mishneh Torah, Human Dispositions 2:3
Rambam rules that one should distance oneself from anger to the ultimate extreme — training oneself to feel no anger even about things that would normally warrant it. He calls anger an extremely bad character trait.
וְכֵן הַכַּעַס מִדָּה רָעָה הִיא עַד לִמְאֹד וְרָאוּי לָאָדָם שֶׁיִּתְרַחֵק מִמֶּנָּה עַד הַקָּצֶה הָאַחֵר. וִילַמֵּד עַצְמוֹ שֶׁלֹּא יִכְעֹס וַאֲפִלּוּ עַל דָּבָר שֶׁרָאוּי לִכְעֹס עָלָיו. אָמְרוּ חֲכָמִים הָרִאשׁוֹנִים כָּל הַכּוֹעֵס כְּאִלּוּ עוֹבֵד עֲבוֹדַת כּוֹכָבִים. לְפִיכָךְ צִוּוּ לְהִתְרַחֵק מִן הַכַּעַס עַד שֶׁיַּנְהִיג עַצְמוֹ שֶׁלֹּא יַרְגִּישׁ אֲפִלּוּ לַדְּבָרִים הַמַּכְעִיסִים וְזוֹ הִיא הַדֶּרֶךְ הַטּוֹבָה.
He should school himself not to become angry even when it is fitting to be angry. If he should wish to arouse fear in his children and household - or within the community, if he is a communal leader - and wishes to be angry at them to motivate them to return to the proper path, he should present an angry front to them to punish them, but he should be inwardly calm. He should be like one who acts out the part of an angry man in his wrath, but is not himself angry. The early Sages said: Anyone who becomes angry is like one who worships idols. This is the good path.
Why it matters — The Rambam's halakhic ruling elevates avoidance of anger to an ethical imperative of the highest order.
