. תָּנוּ רַבָּנַן, ״אֶת מִשְׁפָּטַי תַּעֲשׂוּ״ — דְּבָרִים שֶׁאִלְמָלֵא (לֹא) נִכְתְּבוּ דִּין הוּא שֶׁיִּכָּתְבוּ, וְאֵלּוּ הֵן: עֲבוֹדָה זָרָה, וְגִלּוּי עֲרָיוֹת, וּשְׁפִיכוּת דָּמִים, וְגָזֵל, וּבִרְכַּת הַשֵּׁם. ״אֶת חוּקּוֹתַי תִּשְׁמְרוּ״ — דְּבָרִים שֶׁהַשָּׂטָן מֵשִׁיב עֲלֵיהֶן, וְאֵלּוּ הֵן: אֲכִילַת חֲזִיר, וּלְבִישַׁת שַׁעַטְנֵז, וַחֲלִיצַת יְבָמָה, וְטׇהֳרַת מְצוֹרָע, וְשָׂעִיר הַמִּשְׁתַּלֵּחַ. וְשֶׁמָּא תֹּאמַר מַעֲשֵׂה תוֹהוּ הֵם, תַּלְמוּד לוֹמַר: ״אֲנִי ה׳״, אֲנִי ה׳ חֲקַקְתִּיו, וְאֵין לְךָ רְשׁוּת לְהַרְהֵר בָּהֶן.
The Gemara cites another baraita related to the scapegoat. The Sages taught with regard to the verse: “You shall do My ordinances, and you shall keep My statutes to follow them, I am the Lord your God” (Leviticus 18:4), that the phrase: My ordinances, is a reference to matters that, even had they not been written, it would have been logical that they be written. They are the prohibitions against idol worship, prohibited sexual relations, bloodshed, theft, and blessing God, a euphemism for cursing the Name of God. The phrase: And you shall keep my statutes, is a reference to matters that Satan and the nations of the world challenge because the reason for these mitzvot are not known. They are: The prohibitions against eating pork; wearing garments that are made from diverse kinds of material, i.e., wool and linen; performing the ḥalitza ceremony with a yevama, a widow who must participate in a levirate marriage or ḥalitza; the purification ceremony of the leper; and the scapegoat. And lest you say these have no reason and are meaningless acts, therefore the verse states: “I am the Lord” (Leviticus 18:4), to indicate: I am the Lord, I decreed these statutes and you have no right to doubt them. §
