Bereishit – The Story of Cain and Abel

Genesis 4:1-8

The Torah describes the conflict between Cain and Abel: both bring offerings, God accepts Abel's but not Cain's, and God warns Cain that 'sin crouches at the door.' Cain then rises against his brother and kills him — but the Torah leaves the motive ambiguous, simply saying 'Cain spoke to his brother Abel, and when they were in the field, Cain rose up against his brother and killed him.'

וְאֶל־קַ֥יִן וְאֶל־מִנְחָת֖וֹ לֹ֣א שָׁעָ֑ה וַיִּ֤חַר לְקַ֙יִן֙ מְאֹ֔ד וַֽיִּפְּל֖וּ פָּנָֽיו׃ וַיֹּ֥אמֶר יְהֹוָ֖ה אֶל־קָ֑יִן לָ֚מָּה חָ֣רָה לָ֔ךְ וְלָ֖מָּה נָפְל֥וּ פָנֶֽיךָ׃ הֲל֤וֹא אִם־תֵּיטִיב֙ שְׂאֵ֔ת וְאִם֙ לֹ֣א תֵיטִ֔יב לַפֶּ֖תַח חַטָּ֣את רֹבֵ֑ץ וְאֵלֶ֙יךָ֙ תְּשׁ֣וּקָת֔וֹ וְאַתָּ֖ה תִּמְשׇׁל־בּֽוֹ׃ וַיֹּ֥אמֶר קַ֖יִן אֶל־הֶ֣בֶל אָחִ֑יו וַֽיְהִי֙ בִּהְיוֹתָ֣ם בַּשָּׂדֶ֔ה וַיָּ֥קׇם קַ֛יִן אֶל־הֶ֥בֶל אָחִ֖יו וַיַּהַרְגֵֽהוּ׃

but paid no heed to Cain and his offering. Cain was much distressed and his face fell. And GOD said to Cain, “Why are you distressed, And why is your face fallen? Surely, if you do right, There is uplift. But if you do not do right Sin couches at the door; Its urge is toward you, Yet you can be its master.” Cain said to his brother Abel … and when they were in the field, Cain set upon his brother Abel and killed him.

Why it matters — The primary biblical account of the murder, whose deliberate ambiguity drives all subsequent interpretation.

Bereishit Rabbah – Midrash on Cain and Abel

Bereshit Rabbah 22:7

The Midrash records a dispute about the cause of the quarrel: they divided the world between them and then each claimed the other's portion — one took all the land, the other all movable property. Another opinion: they fought over who would have the Temple site built on his portion. A third opinion: they fought over a woman (the twin sister born with Abel).

וַיֹּאמֶר קַיִן אֶל הֶבֶל אָחִיו וַיְהִי בִּהְיוֹתָם וגו' (בראשית ד, ח), עַל מָה הָיוּ מִדַּיְּנִים, אָמְרוּ בּוֹאוּ וְנַחֲלֹק אֶת הָעוֹלָם, אֶחָד נָטַל הַקַּרְקָעוֹת וְאֶחָד נָטַל אֶת הַמִּטַּלְטְלִין, דֵּין אָמַר אַרְעָא דְּאַתְּ קָאֵם עֲלָהּ דִּידִי, וְדֵין אָמַר מַה דְּאַתְּ לָבֵישׁ דִּידִי, דֵּין אָמַר חֲלֹץ, וְדֵין אָמַר פְּרַח, מִתּוֹךְ כָּךְ (בראשית ד, ח): וַיָּקָם קַיִן אֶל הֶבֶל אָחִיו וַיַּהַרְגֵּהוּ, רַבִּי יְהוֹשֻׁעַ דְּסִכְנִין בְּשֵׁם רַבִּי לֵוִי אָמַר שְׁנֵיהֶם נָטְלוּ אֶת הַקַּרְקָעוֹת, וּשְׁנֵיהֶן נָטְלוּ אֶת הַמִּטַּלְטַלִין, וְעַל מָה הָיוּ מִדַּיְּנִין, אֶלָּא זֶה אוֹמֵר בִּתְחוּמִי בֵּית הַמִּקְדָּשׁ נִבְנֶה וְזֶה אוֹמֵר בִּתְחוּמִי בֵּית הַמִּקְדָּשׁ נִבְנֶה, שֶׁנֶּאֱמַר: יְהוּדָה בַּר אָמֵי אָמַר עַל חַוָּה הָרִאשׁוֹנָה הָיוּ מִדַּיְּנִין, אָמַר רַבִּי אַיְבוּ חַוָּה הָרִאשׁוֹנָה חָזְרָה לַעֲפָרָהּ וְעַל מָה הָיוּ מִדַּיְּנִין, אָמַר רַבִּי הוּנָא תְּאוֹמָה יְתֵרָה נוֹלְדָה עִם הֶבֶל, זֶה אוֹמֵר אֲנִי נוֹטְלָהּ שֶׁאֲנִי בְּכוֹר, וְזֶה אוֹמֵר אֲנִי נוֹטְלָהּ שֶׁנּוֹלְדָה עִמִּי, וּמִתּוֹךְ כָּךְ וַיָּקָם קַיִן.

It was when they were in the field. Cain rose up against Abel his brother and killed him” (Genesis 4:8). “Cain said to Abel his brother. It was when they were…” – about what were they quarreling? This one [Cain] said: ‘I will take her, as I am the firstborn.’ That one [Abel] said: ‘I will take her, as she was born with me.’ As a result: “Cain rose up.”

Why it matters — The richest collection of rabbinic answers to the very question of Cain's motive — property, sacred space, or a woman.

Talmud Bavli – Sanhedrin

Sanhedrin 37b

The Talmud emphasizes the gravity of Cain's act by teaching that whoever destroys a single soul is as if he destroyed an entire world, since all of humanity descended from one person (Adam). The erasure of Abel removed not only him but all his potential descendants.

הֱווּ יוֹדְעִים כּוּ׳. אָמַר רַב יְהוּדָה בְּרֵיהּ דְּרַבִּי חִיָּיא: מְלַמֵּד שֶׁעָשָׂה קַיִן בְּהֶבֶל אָחִיו חַבּוּרוֹת חַבּוּרוֹת, פְּצִיעוֹת פְּצִיעוֹת, שֶׁלֹּא הָיָה יוֹדֵעַ מֵהֵיכָן נְשָׁמָה יוֹצְאָה, עַד שֶׁהִגִּיעַ לְצַוָּארוֹ. וְאָמַר רַב יְהוּדָה בְּרֵיהּ דְּרַבִּי חִיָּיא: מִיּוֹם שֶׁפָּתְחָה הָאָרֶץ אֶת פִּיהָ וְקִיבְּלַתּוּ לְדָמוֹ שֶׁל הֶבֶל, שׁוּב לֹא פָּתְחָה, שֶׁנֶּאֱמַר: ״מִכְּנַף הָאָרֶץ זְמִרֹת שָׁמַעְנוּ צְבִי לַצַּדִּיק״ – מִכְּנַף הָאָרֶץ וְלֹא מִפִּי הָאָרֶץ. אֵיתִיבֵיהּ חִזְקִיָּה אָחִיו: ״וַתִּפְתַּח הָאָרֶץ אֶת פִּיהָ״! אֲמַר לֵיהּ: לְרָעָה פָּתְחָה, לְטוֹבָה לֹא פָּתְחָה. וְאָמַר רַב יְהוּדָה בְּרֵיהּ דְּרַבִּי חִיָּיא: גָּלוּת מְכַפֶּרֶת עָוֹן מֶחֱצָה. מֵעִיקָּרָא כְּתִיב: ״וְהָיִיתִי נָע וְנָד״, וּלְבַסּוֹף כְּתִיב: ״וַיֵּשֶׁב בְּאֶרֶץ נוֹד״.

§ The mishna teaches that the court would say: You should know that cases of capital law are not like cases of monetary law, and would reference the murder of Abel by Cain. Rav Yehuda, son of Rabbi Ḥiyya, says: By employing the plural term for blood, “The voice of your brother’s blood [demei] cries out to Me from the ground” (Genesis 4:10), the verse teaches that Cain caused multiple wounds and multiple injuries to his brother Abel. As Cain did not know from where the soul departs, he struck him multiple times. This continued until he came to his neck and struck him there, whereupon Abel died. And Rav Yehuda, son of Rabbi Ḥiyya, says: From the day the earth opened its mouth and received the blood of Abel, its mouth has not opened again, as it is stated: “From the corner of the earth have we heard songs: Glory to the righteous” (Isaiah 24:16): One can infer that the songs are heard “from the corner of the earth,” but not from the mouth of the earth, as the earth never again opened its mouth. Ḥizkiyya, Rav Yehuda’s brother, raised an objection to Rav Yehuda, son of Rabbi Ḥiyya: The verse states concerning Korah and his assembly: “And the earth opened her mouth and swallowed them up, and their households, and all the men that appertained unto Korah, and all their goods” (Numbers 16:32). Rav Yehuda, son of Rabbi Ḥiyya, said to him: It opened again for a deleterious purpose; it did not open again for a constructive purpose. And Rav Yehuda, son of Rabbi Ḥiyya, says: Exile atones for half of a sin. As initially it is written in the verse concerning Cain that he said: “And I shall be a fugitive [na] and a wanderer [vanad ] in the earth” (Genesis 4:14), and ultimately it is written: “And Cain went out from the presence of the Lord, and dwelt in the land of Nod” (Genesis 4:16). Rav Yehuda, son of Rabbi Ḥiyya, equates “Nod” with “nad,” and understands that Cain was given only the punishment of being a wanderer. Exile atoned for half his sin, thereby negating the punishment of being a fugitive.

Why it matters — Provides the Talmudic framing of why Cain's murder was cosmically catastrophic — all of Abel's unborn children were also killed.

Targum Yerushalmi – Genesis 4:8

Targum Jerusalem, Genesis 4:8

The Targum Yerushalmi fills in the missing words of 'Cain spoke to his brother Abel' with an actual theological debate: Cain denies divine justice (there is no judgment and no Judge, no reward and no punishment), while Abel affirms that the world is governed by mercy and justice. The murder thus stems from a theological dispute about God's governance of the world.

וַאֲמַר קַיִן לְהֶבֶל אָחוּי אִיתָא וְנִפּוּק לְאַפֵּי בָרָא וַהֲוָה כַּד נְפָקוּ תַּרְוֵיהוֹן לְאַפֵּי בָרָא עָנֵי קַיִן וַאֲמַר לְהֶבֶל אָחוּי לֵית דִין וְלֵית דַיָין וְלֵית עֲלָם אוֹחֲרָן וְלָא לְמִתַּן אֲגָר טַב לְצַדִיקַיָא וְלָא לְאִתְפְּרַע מִן רַשִׁיעַיָא וְלָא בְּרַחֲמִין אִיתְבְּרִי עַלְמָא וְלָא בְּרַחֲמִין הוּא מַדְבֵּר מִן בִּגְלַל מַה אִיתְקַבֵּל קוּרְבָּנָךְ מִינָךְ בִּרְעוּ וּמִנִי לָא אִתְקַבֵּל בְּרַעֲוָא עָנֵי הֶבֶל וַאֲמַר לְקַיִן אִית דִין וְאִית דַיָין וְאִית עֲלָם אוֹחֲרָן וְאִית תַּמָן אֲגַר טַב לְצַדִיקַיָיא וּלְאִיתְפְּרַע מֵרַשִׁיעַיָא וּבְרַחֲמִין אִיתְבְּרִי עַלְמָא וּבְרַחֲמִין הוּא מַדְבֵּר בְּרַם בְּפֵירֵי עוֹבָדִין טָבִין הוּא מַדְבֵּר עַל דְהַוָון עוֹבָדַיי תַּקְנִין מִן דִידָךְ אִיתְקַבֵּל קָרְבָּנִי מִנִי בְּרַעֲוָא וּמִינָךְ לָא אִתְקַבֵּל בְּרַעֲוָא וַהֲווֹ תַרְוֵיהוֹן מְנַצִין בְּאַפֵּי בָרָא וְקָם קַיִן עַל הֶבֶל אָחוֹי וְקָטֵל יָתֵיהּ:

And as they two disputed on the face of the field, Kain arose against Habel his brother, and killed him.

Why it matters — Identifies the motive as ideological — a clash over belief in divine justice and reward, with Cain's heresy driving him to murder.

Sforno – Commentary on Genesis 4:5–8

Sforno on Genesis 4:5-8

Sforno explains that Cain's offering was rejected because it lacked proper intention (kavanah) and was not from the choicest of his produce. When God then showed favor to Abel, Cain's wounded ego and deep-seated jealousy erupted into murderous rage — he could not tolerate seeing his brother succeed where he had failed.

וַיִּפְּלוּ פָּנָיו. כִּי כְּשֶׁיֵּשׁ לַקִּלְקוּל אֵיזוֹ תַּקָּנָה, אֵין רָאוּי לְהִצְטַעֵר עַל מַה שֶּׁעָבַר, אֲבָל רָאוּי לְהִשְׁתַּדֵּל לְהַשִּׂיג תִּקּוּן לֶעָתִיד: גַּם כֵּן הַחַטָּאת מוּכָן לְפָנֶיךָ, כִּי תּוֹסִיף עַל חַטָּאתְךָ פֶּשַׁע, שֶׁכָּךְ דַּרְכּוֹ שֶׁל יֵצֶר הָרָע:

Why are you angry. Why are you jealous that I accepted your brother’s offering? I did not do so arbitrarily nor was it unjust.

Why it matters — Highlights the role of improper intention in Cain's offering and traces the murder to wounded pride and uncontrolled jealousy.

Rashi – Commentary on Genesis 4:8

Rashi on Genesis 4:8

Rashi notes that the text says 'Cain spoke to his brother' but records no speech, and cites the Targum Yerushalmi tradition that their quarrel concerned divine judgment. He also entertains the explanation that Cain's anger over the rejected offering overwhelmed him.

נִכְנַס עִמּוֹ בְּדִבְרֵי רִיב וּמַצָּה לְהִתְעוֹלֵל עָלָיו לְהָרְגוֹ.

ויאמר קין אל הבל AND CAIN SPAKE TO ABEL — He began an argument, striving and contending with him, to seek a pretext to kill him.

Why it matters — Classic peshat and midrashic synthesis on the missing dialogue, pointing to jealousy over the offering and theological dispute as twin motives.

Ramban – Commentary on Genesis 4:3–8

Ramban on Genesis 4:3-8

The Ramban analyzes why Cain's offering was rejected (he brought inferior produce) and traces the murder to Cain's failure to accept God's rebuke gracefully. He explains that God's warning — 'sin crouches at the door' — was an invitation to repent, but Cain's pride and jealousy proved stronger than his fear of God.

IS IT NOT THUS, IF THOU MENDEST ‘SE’EITH’. In the opinion of the commentators, this means there is a “lifting” or forgiveness of your sin. And in the opinion of Rabbi Abraham ibn Ezra it means a “lifting” of your face in contrast to [the question G-d asked of Cain]: Why is thy face fallen? For he who is ashamed presses his face downward. Similarly, it is said, And the light of my countenance they cast not down, whereas one who honors him is as if he raises his face upward. This is the sense of the verses: Perhaps he will lift my face; Do not lift the face of the poor. In my opinion the verse means: “If you will mend your ways you will have your rightful superiority in se’eith (dignity) over your brother since you are the firstborn.” And this is the meaning of [G-d’s question to him]: Why art thou wroth? For by virtue of his feeling ashamed before his brother, his face fell, and because of his jealousy of him he killed him, and now the Eternal told him: Why art thou wroth regarding your brother, and why is thy face fallen on account of him? Is it not thus! If thou mendest, you will have superiority in dignity over your brother, and if thou dost not mend, evil will come upon you not only because of him [your brother], for at the door of your house your sin lurks causing you to stumble in all your endeavors. AND CAIN SPOKE TO ABEL HIS BROTHER. He began a conversation of argument and contention with him in order to seek a pretext against him and so kill him. This is the language of Rashi. Rabbi Abraham ibn Ezra said that the interpretation that appears most likely to him is that Cain related to Abel all the chastisements with which G-d had reprimanded him [and Cain accused Abel of having brought them upon him]. But in my opinion it is connected with the following words of Scripture: and it came to pass, when they were in the field, meaning that Cain said to Abel, “Let us go forth into the field,” and there he secretly killed him. It is possible that his intention in killing Abel was that the world be built up from himself for he thought that his father would not have any more children. He also feared that the main building up of the world might be from his brother, [which seemed likely since it was he] whose offering had been favorably accepted.

Why it matters — Locates the root cause of the murder in Cain's prideful refusal to accept divine correction — a deep character flaw made lethal.
