Vayikra 18:1-5 ויקרא י״ח:א׳-ה׳

אני ה' אלהיכם. אֲנִי הוּא שֶׁאָמַרְתִּי בְסִינַי אָנֹכִי ה' אֱלֹהֶיךָ וְקִבַּלְתֶּם עֲלֵיכֶם מַלְכוּתִי, מֵעַתָּה קַבְּלוּ גְזֵרוֹתָי; רַבִּי אוֹמֵר גָּלוּי וְיָדוּעַ לְפָנָיו שֶׁסּוֹפָן לִנָּתֵק בַּעֲרָיוֹת בִּימֵי עֶזְרָא, לְפִיכָךְ בָּא עֲלֵיהֶם בִּגְזֵרָה אני ה' אלהיכם — דְּעוּ מִי גוֹזֵר עֲלֵיכֶם, דַּיָּן לִפָּרַע וְנֶאֱמָן לְשַׁלֵּם שָׂכָר (עי' ספרא):

אני ה' אלהיכם I AM THE LORD YOUR GOD — I am He Who spoke on Mount Sinai “I am the Lord thy God" and Whose kingship you then accepted; now, therefore, accept My decrees! Rabbi Judah han-Nasi said: It was manifest and known to Him that in the days of Ezra they would ultimately revolt against restricting sexual relations, He therefore came to them with a decree emphasized by the words: "I am The Lord your God" — understand well Who it is that imposes this decree upon you, — the Judge (אלהיכם) Whose function it is to punish but Who is certain also to give a reward ('‎ה‎) (cf. Sifra, Acharei Mot, Section 8 1).

כמעשה ארץ מצרים. מַגִּיד שֶׁמַּעֲשֵׂיהֶם שֶׁל מִצְרִיִּים וְשֶׁל כְּנַעֲנִיִּים מְקֻלְקָלִים מִכָּל הָאֻמּוֹת, וְאוֹתוֹ מָקוֹם שֶׁיָּשְׁבוּ בוֹ יִשְׂרָאֵל מְקֻלְקָל מִן הַכֹּל:

כמעשה ארץ מצרים AFTER THE DEEDS OF THE LAND OF EGYPT… [SHALL YE NOT DO] — This tells us that the deeds of the Egyptians and the Canaanites were more corrupt than those of all other nations, and that the district of Egypt in which the Israelites had resided (אשר ישבתם בה) was even more corrupt than all the rest of Egypt (Sifra, Acharei Mot, Section 8 3).

אשר אני מביא אתכם שמה. מַגִּיד שֶׁאוֹתָן עֲמָמִין שֶׁכִּבְּשׁוּ יִשְֹרָאֵל מְקֻלְקָלִים מִכֻּלָּם (שם):

אשר אני מביא אתכם שמה [AND AFTER THE DEEDS OF THE LAND OF CANAAN] WHITHER I BRING YOU [SHALL YE NOT DO] — This again tells us that those Canaanitish clans whom Israel subdued were more corrupt than all the others of them (Sifra, Acharei Mot, Section 8 4).

ובחקתיהם לא תלכו. מַה הִנִּיחַ הַכָּתוּב שֶׁלֹּא אָמַר? אֶלָּא אֵלּוּ נִימוֹסוֹת שֶׁלָּהֶן — דְּבָרִים הַחֲקוּקִין לָהֶם — כְּגוֹן טַרְטִיָּאוֹת וְאִצְטַדִיָּאוֹת, רַבִּי מֵאִיר אוֹמֵר, אֵלּוּ דַּרְכֵי הָאֱמוֹרִי שֶׁמָּנוּ חֲכָמִים (שם):

ובחקתיהם לא תלכו NEITHER SHALL YE WALK IN THEIR ORDINANCES — What has Scripture left unsaid when it spoke of the deeds of the Egyptians and Canaanites that it felt compelled to add ובחקתיהם לא תלכו But by these latter words it refers to their social customs — things which have assumed for them the character of a law as, for instance, the frequenting of theaters and race-courses. Rabbi Meir, however, said: These (חקתיהם) refer to the "ways of the Amorites" (superstitious practices) which our Rabbis have enumerated (Shabbat 67a; Sifra, Acharei Mot, Section 8 8; cf. also Tosefta Shabbat 7).

את משפטי תעשו. אֵלּוּ דְּבָרִים הָאֲמוּרִים בַּתּוֹרָה בְּמִשְׁפָּט, שֶׁאִלּוּ לֹא נֶאֶמְרוּ הָיוּ כְדַאי לְאָמְרָן:

את משפטי תעשו YE SHALL DO MY JUDGMENTS — Matters prescribed in the Torah which are in conformity with the human feeling of justice such as one feels ought to be ordained if they had not been already ordained by the Torah.

ואת חקתי תשמרו. דְּבָרִים שֶׁהֵן גְּזֵרַת הַמֶּלֶךְ, שֶׁיֵּצֶר הָרַע מֵשִׁיב עֲלֵיהֶם לָמָּה לָנוּ לְשָׁמְרָן? וְאֻמּוֹת הָעוֹלָם מְשִׁיבִין עֲלֵיהֶם, כְּגוֹן אֲכִילַת חֲזִיר וּלְבִישַׁת שַׁעַטְנֵז וְטָהֳרַת מֵי חַטָּאת, לְכָךְ נֶאֱמַר אני ה', גָּזַרְתִּי עֲלֵיכֶם, אֵי אַתָּה רַשַּׁאי לִפָּטֵר (יומא ס"ז):

ואת חקתי תשמרו AND KEEP MINE ORDINANCES — matters which are decrees of the King (promulgated without any reason being stated) against which the evil inclination raises objections: "Why should we observe them and against which also the nations of the world raise objections, as e. g., the prohibition of eating swine’s flesh, of wearing clothes of a mixture of wool and linen, the purgatory power of "water mingled with the ashes of the Red Heifer" (טהרת מי חטאת) — therefore it is stated: "I", the Lord, have enacted this for you — you are not at liberty to evade the obligation (Yoma 67b).

ללכת בהם. אַל תִּפָּטֵר מִתּוֹכָם, שֶׁלֹּא תֹאמַר לָמַדְתִּי חָכְמַת יִשְׂרָאֵל אֵלֵךְ וְאֶלְמַד חָכְמַת הָאֻמּוֹת (ספרא):

ללכת בהם TO WALK IN THEM — do not free yourselves from their environment, i.e. that you must not say, I have acquired Jewish wisdom, now I will go and acquire the wisdom of the other peoples of the world in order to walk in their ways.

ושמרתם את חקתי וגו'. לְרַבּוֹת שְׁאָר דִּקְדּוּקֵי הַפָּרָשָׁה, שֶׁלֹּא פֵּרֵט הַכָּתוּב בָּהֶם; דָּבָר אַחֵר לִתֵּן שְׁמִירָה וַעֲשִׂיָּה לַחֻקִּים וּשְׁמִירָה וַעֲשִׂיָּה לַמִּשְׁפָּטִים, לְפִי שֶׁלֹּא נָתַן אֶלָּא עֲשִׂיָּה לַמִּשְׁפָּטִים וּשְׁמִירָה לַחֻקִּים (ספרא):

'ושמרתם את חקתי וגו‎ YE SHALL THEREFORE KEEP MY ORDINANCES — [This is not a mere repetition of v. 4 but is intended] to include other details of the laws mentioned in this chapter which Scripture does not expressly mention. Another explanation is: Scripture makes this repetition in order to attach the commands of “observing" (שמירה) and "performing" (עשיה) to the חוקים, and the commands of שמירה and עשיה to the משפטים, for in v. 4 it uses the term עשיה only in connection with the משפטים, and that of שמירה only with reference to the חוקים (Sifra, Acharei Mot, Section 8 10).

וחי בהם. לָעוֹלָם הַבָּא, שֶׁאִם תֹּאמַר בָּעוֹלָם הַזֶּה וַהֲלֹא סוֹפוֹ הוּא מֵת (שם):

וחי בהם means, THAT HE SHALL LIVE THROUGH THEM in the world to come (eternal life). For if you say it means that he shall live in this world, is it not a fact that in the end he must die! (Sifra, Acharei Mot, Section 8 10; cf. also Targ. Onkelos)

אני ה'. נֶאֱמָן לְשַׁלֵּם שָׂכָר (שם):

'אני ה‎ I AM THE LORD, Who am faithful to pay you your reward (Sifra, Acharei Mot, Section 8 10).
