Va-era: How Hearts Harden

(א) בָּרוּךְ אַתָּה יְהֹוָה אֱלֹהֵֽינוּ מֶֽלֶךְ הָעוֹלָם אֲשֶׁר קִדְּ֒שָֽׁנוּ בְּמִצְוֹתָיו וְצִוָּנוּ לַעֲסֹק בְּדִבְרֵי תוֹרָה:

(1) Blessed are You, Adonoy our God, Ruler of the Universe, Who sanctified us with commandments and commanded us to be engrossed in the words of Torah.

וַיְדַבֵּ֧ר יְהוָ֛ה אֶל־מֹשֶׁ֥ה לֵּאמֹ֖ר אֲנִ֣י יְהוָ֑ה דַּבֵּ֗ר אֶל־פַּרְעֹה֙ מֶ֣לֶךְ מִצְרַ֔יִם אֵ֛ת כָּל־אֲשֶׁ֥ר אֲנִ֖י דֹּבֵ֥ר אֵלֶֽיךָ׃ וַיֹּ֥אמֶר מֹשֶׁ֖ה לִפְנֵ֣י יְהוָ֑ה הֵ֤ן אֲנִי֙ עֲרַ֣ל שְׂפָתַ֔יִם וְאֵ֕יךְ יִשְׁמַ֥ע אֵלַ֖י פַּרְעֹֽה׃ (פ) וַיֹּ֤אמֶר יְהוָה֙ אֶל־מֹשֶׁ֔ה רְאֵ֛ה נְתַתִּ֥יךָ אֱלֹהִ֖ים לְפַרְעֹ֑ה וְאַהֲרֹ֥ן אָחִ֖יךָ יִהְיֶ֥ה נְבִיאֶֽךָ׃ אַתָּ֣ה תְדַבֵּ֔ר אֵ֖ת כָּל־אֲשֶׁ֣ר אֲצַוֶּ֑ךָּ וְאַהֲרֹ֤ן אָחִ֙יךָ֙ יְדַבֵּ֣ר אֶל־פַּרְעֹ֔ה וְשִׁלַּ֥ח אֶת־בְּנֵֽי־יִשְׂרָאֵ֖ל מֵאַרְצֽוֹ׃ וַאֲנִ֥י אַקְשֶׁ֖ה אֶת־לֵ֣ב פַּרְעֹ֑ה וְהִרְבֵּיתִ֧י אֶת־אֹתֹתַ֛י וְאֶת־מוֹפְתַ֖י בְּאֶ֥רֶץ מִצְרָֽיִם׃ וְלֹֽא־יִשְׁמַ֤ע אֲלֵכֶם֙ פַּרְעֹ֔ה וְנָתַתִּ֥י אֶת־יָדִ֖י בְּמִצְרָ֑יִם וְהוֹצֵאתִ֨י אֶת־צִבְאֹתַ֜י אֶת־עַמִּ֤י בְנֵֽי־יִשְׂרָאֵל֙ מֵאֶ֣רֶץ מִצְרַ֔יִם בִּשְׁפָטִ֖ים גְּדֹלִֽים׃ וְיָדְע֤וּ מִצְרַ֙יִם֙ כִּֽי־אֲנִ֣י יְהוָ֔ה בִּנְטֹתִ֥י אֶת־יָדִ֖י עַל־מִצְרָ֑יִם וְהוֹצֵאתִ֥י אֶת־בְּנֵֽי־יִשְׂרָאֵ֖ל מִתּוֹכָֽם׃ וַיַּ֥עַשׂ מֹשֶׁ֖ה וְאַהֲרֹ֑ן כַּאֲשֶׁ֨ר צִוָּ֧ה יְהוָ֛ה אֹתָ֖ם כֵּ֥ן עָשֽׂוּ׃

And Hashem said to Moses, “I am Hashem; speak to Pharaoh king of Egypt all that I will tell you,” Moses appealed to Hashem, saying, “See, I am of impeded speech; how then should Pharaoh heed me!” Hashem replied to Moses, “See, I place you in the role of God to Pharaoh, with your brother Aaron as your prophet. You shall repeat all that I command you, and your brother Aaron shall speak to Pharaoh to let the Israelites depart from his land. But I will harden Pharaoh’s heart, that I may multiply My signs and marvels in the land of Egypt. When Pharaoh does not heed you, I will lay My hand upon Egypt and deliver My ranks, My people the Israelites, from the land of Egypt with extraordinary chastisements. And the Egyptians shall know that I am Hashem, when I stretch out My hand over Egypt and bring out the Israelites from their midst.” This Moses and Aaron did; as Hashem commanded them, so they did.

וַיָּבֹ֨א מֹשֶׁ֤ה וְאַהֲרֹן֙ אֶל־פַּרְעֹ֔ה וַיַּ֣עַשׂוּ כֵ֔ן כַּאֲשֶׁ֖ר צִוָּ֣ה יְהוָ֑ה וַיַּשְׁלֵ֨ךְ אַהֲרֹ֜ן אֶת־מַטֵּ֗הוּ לִפְנֵ֥י פַרְעֹ֛ה וְלִפְנֵ֥י עֲבָדָ֖יו וַיְהִ֥י לְתַנִּֽין׃ וַיִּקְרָא֙ גַּם־פַּרְעֹ֔ה לַֽחֲכָמִ֖ים וְלַֽמְכַשְּׁפִ֑ים וַיַּֽעֲשׂ֨וּ גַם־הֵ֜ם חַרְטֻמֵּ֥י מִצְרַ֛יִם בְּלַהֲטֵיהֶ֖ם כֵּֽן׃ וַיַּשְׁלִ֙יכוּ֙ אִ֣ישׁ מַטֵּ֔הוּ וַיִּהְי֖וּ לְתַנִּינִ֑ם וַיִּבְלַ֥ע מַטֵּֽה־אַהֲרֹ֖ן אֶת־מַטֹּתָֽם׃ וַיֶּחֱזַק֙ לֵ֣ב פַּרְעֹ֔ה וְלֹ֥א שָׁמַ֖ע אֲלֵהֶ֑ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה׃ (פ)

So Moses and Aaron came before Pharaoh and did just as Hashem had commanded: Aaron cast down his rod in the presence of Pharaoh and his courtiers, and it turned into a serpent. Then Pharaoh, for his part, summoned the wise men and the sorcerers; and the Egyptian magicians, in turn, did the same with their spells; each cast down his rod, and they turned into serpents. But Aaron’s rod swallowed their rods. Yet Pharaoh’s heart stiffened and he did not heed them, as Hashem had said.

וַיַּֽעֲשׂוּ־כֵן֩ מֹשֶׁ֨ה וְאַהֲרֹ֜ן כַּאֲשֶׁ֣ר ׀ צִוָּ֣ה יְהוָ֗ה וַיָּ֤רֶם בַּמַּטֶּה֙ וַיַּ֤ךְ אֶת־הַמַּ֙יִם֙ אֲשֶׁ֣ר בַּיְאֹ֔ר לְעֵינֵ֣י פַרְעֹ֔ה וּלְעֵינֵ֖י עֲבָדָ֑יו וַיֵּהָֽפְכ֛וּ כָּל־הַמַּ֥יִם אֲשֶׁר־בַּיְאֹ֖ר לְדָֽם׃ וְהַדָּגָ֨ה אֲשֶׁר־בַּיְאֹ֥ר מֵ֙תָה֙ וַיִּבְאַ֣שׁ הַיְאֹ֔ר וְלֹא־יָכְל֣וּ מִצְרַ֔יִם לִשְׁתּ֥וֹת מַ֖יִם מִן־הַיְאֹ֑ר וַיְהִ֥י הַדָּ֖ם בְּכָל־אֶ֥רֶץ מִצְרָֽיִם׃ וַיַּֽעֲשׂוּ־כֵ֛ן חַרְטֻמֵּ֥י מִצְרַ֖יִם בְּלָטֵיהֶ֑ם וַיֶּחֱזַ֤ק לֵב־פַּרְעֹה֙ וְלֹא־שָׁמַ֣ע אֲלֵהֶ֔ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה׃ וַיִּ֣פֶן פַּרְעֹ֔ה וַיָּבֹ֖א אֶל־בֵּית֑וֹ וְלֹא־שָׁ֥ת לִבּ֖וֹ גַּם־לָזֹֽאת׃ וַיַּחְפְּר֧וּ כָל־מִצְרַ֛יִם סְבִיבֹ֥ת הַיְאֹ֖ר מַ֣יִם לִשְׁתּ֑וֹת כִּ֣י לֹ֤א יָֽכְלוּ֙ לִשְׁתֹּ֔ת מִמֵּימֵ֖י הַיְאֹֽר׃

Moses and Aaron did just as Hashem commanded: he lifted up the rod and struck the water in the Nile in the sight of Pharaoh and his courtiers, and all the water in the Nile was turned into blood and the fish in the Nile died. The Nile stank so that the Egyptians could not drink water from the Nile; and there was blood throughout the land of Egypt. But when the Egyptian magicians did the same with their spells, Pharaoh’s heart stiffened and he did not heed them—as Hashem had spoken. Pharaoh turned and went into his palace, paying no regard even to this. And all the Egyptians had to dig round about the Nile for drinking water, because they could not drink the water of the Nile.

וַיַּעֲשׂוּ־כֵ֨ן הַחַרְטֻמִּ֧ים בְּלָטֵיהֶ֛ם לְהוֹצִ֥יא אֶת־הַכִּנִּ֖ים וְלֹ֣א יָכֹ֑לוּ וַתְּהִי֙ הַכִּנָּ֔ם בָּאָדָ֖ם וּבַבְּהֵמָֽה׃ וַיֹּאמְר֤וּ הַֽחַרְטֻמִּים֙ אֶל־פַּרְעֹ֔ה אֶצְבַּ֥ע אֱלֹהִ֖ים הִ֑וא וַיֶּחֱזַ֤ק לֵב־פַּרְעֹה֙ וְלֹֽא־שָׁמַ֣ע אֲלֵהֶ֔ם כַּאֲשֶׁ֖ר דִּבֶּ֥ר יְהוָֽה׃ (ס)

The magicians did the like with their spells to produce lice, but they could not. The vermin remained upon man and beast; and the magicians said to Pharaoh, “This is the finger of God!” But Pharaoh’s heart stiffened and he would not heed them, as Hashem had spoken.

וַיַּכְבֵּ֤ד פַּרְעֹה֙ אֶת־לִבּ֔וֹ גַּ֖ם בַּפַּ֣עַם הַזֹּ֑את וְלֹ֥א שִׁלַּ֖ח אֶת־הָעָֽם׃ (פ)
But Pharaoh became stubborn this time also, and would not let the people go.
וַיִּקְח֞וּ אֶת־פִּ֣יחַ הַכִּבְשָׁ֗ן וַיַּֽעַמְדוּ֙ לִפְנֵ֣י פַרְעֹ֔ה וַיִּזְרֹ֥ק אֹת֛וֹ מֹשֶׁ֖ה הַשָּׁמָ֑יְמָה וַיְהִ֗י שְׁחִין֙ אֲבַעְבֻּעֹ֔ת פֹּרֵ֕חַ בָּאָדָ֖ם וּבַבְּהֵמָֽה׃ וְלֹֽא־יָכְל֣וּ הַֽחַרְטֻמִּ֗ים לַעֲמֹ֛ד לִפְנֵ֥י מֹשֶׁ֖ה מִפְּנֵ֣י הַשְּׁחִ֑ין כִּֽי־הָיָ֣ה הַשְּׁחִ֔ין בַּֽחֲרְטֻמִּ֖ם וּבְכָל־מִצְרָֽיִם׃ וַיְחַזֵּ֤ק יְהוָה֙ אֶת־לֵ֣ב פַּרְעֹ֔ה וְלֹ֥א שָׁמַ֖ע אֲלֵהֶ֑ם כַּאֲשֶׁ֛ר דִּבֶּ֥ר יְהוָ֖ה אֶל־מֹשֶֽׁה׃ (ס)

So they took soot of the kiln and appeared before Pharaoh; Moses threw it toward the sky, and it caused an inflammation breaking out in boils on man and beast. The magicians were unable to confront Moses because of the inflammation, for the inflammation afflicted the magicians as well as all the other Egyptians. But Hashem stiffened the heart of Pharaoh, and he would not heed them, just as Hashem had told Moses.

ואני אקשה. מֵאַחַר שֶׁהִרְשִׁיעַ וְהִתְרִיס כְּנֶגְדִּי, וְגָלוּי לְפָנַי שֶׁאֵין נַחַת רוּחַ בָּאֻמּוֹת לָתֵת לֵב שָׁלֵם לָשׁוּב, טוֹב שֶׁיִּתְקַשֶּׁה לִבּוֹ, לְמַעַן הַרְבּוֹת בּוֹ אוֹתוֹתַי, וְתַכִּירוּ אַתֶּם אֶת גְּבוּרָתִי. וְכֵן מִדָּתוֹ שֶׁל הַקָּבָּ"ה, מֵבִיא פֻּרְעָנוּת עַל הָאֻמּוֹת כְּדֵי שֶׁיִּשְׁמְעוּ יִשְׂרָאֵל וְיִירְאוּ, שֶׁנֶּאֱ' "הִכְרַתִּי גוֹיִם נָשַׁמּוּ פִּנּוֹתָם … אָמַרְתִּי אַךְ תִּירְאִי אוֹתִי תִּקְחִי מוּסָר" (צפניה ג'); וְאַעַפִּ"כֵ בְּחָמֵשׁ מַכּוֹת הָרִאשׁוֹנוֹת לֹא נֶאֱמַר וַיְחַזֵּק ה' אֶת לֵב פַּרְעֹה, אֶלָּא וַיֶּחֱזַק לֵב פַּרְעֹה (תנחומא):
ואני אקשה AND I WILL ALLOW [PHARAOH’S HEART] TO HARDEN — Since he has wickedly resisted Me, and it is manifest to Me that the heathen nations find no spiritual satisfaction in setting their whole heart to return to Me penitently, it is better that his heart should be hardened in order that My signs may be multiplied against him so that ye may recognise My divine power. Such, indeed, is the method of the Holy One, blessed be He: He brings punishment upon the nations so that Israel may hear of it and fear Him, as it is said, (Zephaniah 3:6, 3:7) “I have cut off nations, their corners are desolate etc. … I said: Surely thou wilt fear Me, thou wilt receive correction” (cf. Yevamot 63a). Nevertheless, in the case of the first five plagues it is not stated, “The Lord hardened Pharaoh’s heart” but “Pharaoh’s heart was hardened” (Midrash Tanchuma, Vaera 3).
ויחזק ה' את לב פרעה. זו מכה ששית נאמר בה ויחזק ה' כי בחמש מכות ראשונות לא נאמר בהן כן כי אין החזוק מאתו יתברך כי אם מתוך כובד לבו של פרעה ומתוך שהיו החרטומים מחזקים את לבו ומתפארים בחכמתם אצלו, אבל עתה במכת השחין לא באו בהיכל מלך פנימה ולא נראו לפני משה כלל כי נתביישו בהיותם מוכי שחין ואין מחזיק ביד פרעה ואין מדבר על לבו ואולי היה נמלך לשלחם אלא שהיתה סבה מאת השי"ת מכאן ואילך.
. ויחזק ה' את לב פרעה, “G’d hardened the heart of Pharaoh.” This was the sixth plague already and it is the first time that the Torah writes that it was G’d who made Pharaoh’s heart strong. Up until now he had hardened his heart unassisted by G’d but due to other considerations as we explained. Now there were no sorcerers who would have lent backbone to Pharaoh by their very presence and would have caused him to remain obstinate. They were ashamed to appear in public as they themselves were suffering from the symptoms of this שחין פורח אבעבעת. Had G’d not interfered at this point, Pharaoh might have capitulated and perhaps would have decided to let the Israelites go.
ואני אקשה את לב פרעה אמרו במדרש רבה (שמו''ר ה ו) גילה לו שהוא עתיד לחזק את לבו בעבור לעשות בו הדין, תחת שהעבידם בעבודה קשה. ועוד שם (יג ד) כי אני הכבדתי את לבו (להלן י א), אמר רבי יוחנן מכאן פתחון פה למינין לומר לא היתה ממנו שיעשה תשובה. אמר רבי שמעון בן לקיש יסתם פיהם של מינין, אלא אם ללצים הוא יליץ (משלי ג לד), מתרה בו פעם ראשונה ושניה ושלישית ואינו חוזר בו והוא נועל בו דלת מן התשובה כדי לפרוע ממנו מה שחטא. כך פרעה הרשע, כיון ששגר הקב''ה אצלו חמש פעמים ולא השגיח על דבריו, אמר לו הקב''ה אתה הקשית את ערפך והכבדת את לבך, הריני מוסיף לך טומאה על טומאתך:
והנה פירשו בשאלה אשר ישאלו הכל, אם השם הקשה את לבו מה פשעו, ויש בו שני טעמים ושניהם אמת האחד, כי פרעה ברשעו אשר עשה לישראל רעות גדולות חנם, נתחייב למנוע ממנו דרכי תשובה, כאשר באו בזה פסוקים רבים בתורה ובכתובים, ולפי מעשיו הראשונים נדון. והטעם השני, כי היו חצי המכות עליו בפשעו, כי לא נאמר בהן רק ויחזק לב פרעה (להלן פסוק יג, כב, ח טו), ויכבד פרעה את לבו (להלן ח כח, ט ז). הנה לא רצה לשלחם לכבוד השם, אבל כאשר גברו המכות עליו ונלאה לסבול אותם, רך לבו והיה נמלך לשלחם מכובד המכות, לא לעשות רצון בוראו. ואז הקשה השם את רוחו ואמץ את לבבו למען ספר שמו, כענין שכתוב והתגדלתי והתקדשתי ונודעתי לעיני גוים רבים וגו' (יחזקאל לח כג):
ואשר אמר קודם המכות (לעיל ד כא) ואני אחזק את לבו ולא ישלח את העם, יודיע למשה העתיד לעשות בו במכות האחרונות, כענין שאמר (לעיל ג יט) ואני ידעתי כי לא יתן אתכם מלך מצרים להלוך וזה טעם ואני אקשה את לב פרעה והרבתי את אותותי, כלומר שאקשה לבו למען רבות מופתי בארץ מצרים. כי בחמש מכות האחרונות גם בטביעת הים נאמר ויחזק ה' (להלן יד ח), כי לב מלך ביד ה' על כל אשר יחפוץ יטנו (משלי כא א):
And I will harden Pharaoh’s heart – they said in the Midrash Rabbah (5:6) that [God] revealed to him that [God] would in the future harden [Pharaoh’s] heart so that judgment would be done on him for enslaving them with hard labor. And we read more there (13:4) because I made his heart heavy (Shemot 10:1) – from this verse, said Rabbi Yochanan, the minim say that he had no chance of doing teshuvah. Rabbi Shimon ben Lakish answered: ‘let the mouths of the minim be closed, rather He laughs at mockers (Mishlei 3:34), he was warned once, and twice and three times and he did not repent, and He closes the door of teshuvah so to extract [retribution] from him what he sinned. So with the evil Pharaoh, God sent [warnings] to him five times and he did not listen to [God’s] words, God said to him: ‘you stiffened your neck and you made your own heart heavy, behold I am going to add impurity to your impurity.
And here is the answer to the question that everyone asks: If God hardened Pharaoh’s heart, what then was his transgression [since he had no choice]? There are two answers, which both hold true: First, Pharaoh, in his wickedness, had unjustifiably treated the Jews terribly, so he was punished with the withdrawal of the path of repentance, and there are many verses regarding this in the Torah and the Writings, and he was punished by his original deeds. Secondly, only the second half of the [ten] plagues were brought upon Egypt due to Pharaoh’s transgressions, as the Torah states, And Pharaoh’s heart was strengthened, (Shemot 7:13, 26; 8:15), and Pharaoh hardened his heart (ibid. 8:28, 9:7). He did not want to send the Jews out of Egypt for the glory of God; rather, when the plagues increased and he was becoming too worn out to withstand them, his heart softened and he decided to send them out because of the severity of the plagues themselves, but not in order to do the will of his Creator. Therefore, God strengthened his spirit and gave courage to his heart so that His Name would be declared [throughout the world], as we read: Thus will I magnify Myself, and sanctify Myself, and I will make Myself known in the eyes of many nations; and they shall know that I am Adønαi. (Ez. 38:23).
And that that is written before the plagues (Shemot / Ex. 3:19) and I know that the king of Egypt will not let you go, this is the reason for and I will stiffen Pharaoh’s heart and multiply My wonders that is to say that I will stiffen his heart so as to increase my wonders in the land of Egypt, because in the last five plagues, and also in the drowning at the sea it is written and Adønαi strenghthened (14:8) because the heart of the king is in the hand of Adønαi He turns it how He wants.

And, it is possible that a man should commit either one grievous iniquity or a multitude of sins so that the Judge of Truth will decree against him that, whereas this sinner committed those sins of his own free will and consciously, repentance should be witheld from him altogether, and grant him no leave to repent, so that he might die and perish in the iniquity he committed. Even this is what the Holy One, blessed is He! said through Isaiah: "Make the heart of this people fat, and make their eyes heavy, and shut their eyes; lest they, seeing with their eyes, and hearing with their ears, and understanding with their heart will return and be healed" (Is. 6.10). It is, moreover, said: "But they mocked the messengers of God, and despised His words and scoffed at His prophets, until the wrath of the Lord arose against His people till there was no remedy". (II Chro. 36.16)—as if saying: "They sinned of their own free will and they have multiplied iniquities, until their guilt carried the punishment to withold repentance from them, which is the remedy". It is, therefore, written in the Torah; "And I will harden Pharaoh's heart" (Ex. 14.4), because at the beginning he sinned of his own free will, and meted out evil to Israel who sojourned in his land, even as it is said: "Come, let us deal wisely with them" (Ibid. 1.10). Thereat justice demanded to withold repentance from him, so that due punishment might be visited upon him. Wherefor, the Holy One, blessed is He! hardened his heart. If it be so, then why did He delegate Moses to him, charging him to let Israel go forth and turn to repentance seeing that the Holy One, blessed is He! long since told him thou wilt not let them go forth, saying: "But as for thee and thy servants, I know that ye will not yet fear the Lord God" (Ibid. 9.30), and again saying: "But in very deed for this cause have I made thee to stand, to show thee My power, and that My name be declared throughout all the earth"(Ibid. –16)? To demonstrate to the future generations whenever the Holy One, blessed is He! witholds repentance from a sinner he can not repent, but must die in the original evil which he perpetrated of his own free will. Sihon, too, by the measure of his iniquity became guilty of an offence which carried the punishment to have repentance witheld from him, even as it is said: "For the Lord thy God hardened his spirit, and made his heart obstinate" (Deut. 2.30). Likewise the Canaanites, according to their abominations, did He withold repentance from them so that they engaged Israel in battle, even as it is said: "For it was of the Lord, to harden their hearts, to come against Israel in battle, that they might be utterly destroyed" (Joshua, 11.20). Even so was with Israel in the days of Elijah, because of the multiplied iniquity repentance was witheld from the gross evildoers, for it is said: "For Thou didst turn their heart backward" (I. Kings, 18.37)—as if saying: "Thou didst withold repentance from them". Thus, as a consequence hereof, we must say: God's predestination prompted not Pharaoh to wrong Israel, nor Sihon to sin in his land, nor the Canaanites to be abominable, nor Israel to worship idolatry; for they all sinned of their own free will and accord, and, therefore, were they all guilty of an offence which carries along the punishment to withold repentance from them.
From “What is Smart Is Not Always What is Right—Tevet 5778” by Dena Weiss, available at https://www.hadar.org/torah-resource/what-smart-not-always-what-right#source-6337
The claim that God is being unjust in manipulating Pharaoh and subjecting him and his people to the plagues on illegitimate grounds, makes two unnecessary, and possibly incorrect, assumptions. First, it assumes that the plagues are coming to Pharaoh and his people on account of Pharaoh’s refusal to let God’s people go at the time that Moshe asks. However, it is equally, if not more, reasonable, to assume that the plagues are coming because Pharaoh had enslaved God’s people in the first place and caused them to suffer for the decades prior. Pharaoh is not being indicted on this momentary refusal to emancipate his slaves, but rather on his history of abuse. . .
The second assumption in the critique of God’s having hardened Pharaoh’s heart is that this hardening has the effect of making Pharaoh behave in a way that he was not before and would not be otherwise. It asserts that if God had left Pharaoh’s heart alone, then Pharaoh would be free to do—and therefore would do—the right thing. This understanding relies on a definition of the heart as the seat of the will—a hard heart makes you obstinate and unwilling to do what is right and a soft heart makes you yielding, impressionable, good.
However, when the Torah describes the Jewish people as obstinate and sinful, it refers to them not as stiff in their hearts, but rather, as stiff in their necks, .קְשֵׁה עֹרֶף Biblical literature often treats the heart as the location of the intellect. As Nahum M. Sarna writes in his book on Sefer Shemot, Exploring Exodus , “Man’s thoughts, his intellectual activity, the cognitive, conative, and affective aspects of his personality, are all regarded as issuing from the heart.” We see the heart as knowing and wise throughout the Torah, and perhaps most beautifully when God describes the skill and wisdom involved in the crafting of the mishkan and its furnishings, where He refers to the artisans as חֲכַם לֵב , wise-hearted.
Consequently, when God (or Pharaoh) hardens or reinforces Pharaoh’s heart, what is being strengthened is Pharaoh’s ability to reason. God is primarily influencing his intelligence. He makes Pharaoh strong of mind and encourages him to think that he is being clever and that he is being strategic, which masks that he is in fact merely being cruel. God doesn’t make Pharaoh tough, so much as He makes him sharp. Pharaoh’s cruelty and propensity to sin is not what God is manipulating; God is strengthening Pharaoh’s ability to rationalize this behavior. Rationalizing a behavior doesn’t necessarily determine whether or not the action will take place, but rather how it should be evaluated, how one thinks about what has been done.
