The Civil Laws are Also from Mount Sinai

(א) וְאֵ֙לֶּה֙ הַמִּשְׁפָּטִ֔ים אֲשֶׁ֥ר תָּשִׂ֖ים לִפְנֵיהֶֽם׃

(1) These are the rules that you shall set before them:

Shemot, Va'eira, Bo: Story of Egypt
Beshalach: Splitting the Red Sea, The Manna from Heaven, 3 days without water, Amalek
Yitro: Yitro Arrives, 10 Commandments, Laws about the Altar
Mishpatim: The Civil Laws, End of the Story of the Giving of the Torah
Terumah, Tetzaveh: Commands from Hashem to Moshe about building the Mishkan
Ki Tisa: Story of the Golden Calf
Vayakhel, Pikudei: The construction of the Mishkan

שמות ט״ו:כ״ה

(כה) וַיִּצְעַ֣ק אֶל־יְהֹוָ֗ה וַיּוֹרֵ֤הוּ יְהֹוָה֙ עֵ֔ץ וַיַּשְׁלֵךְ֙ אֶל־הַמַּ֔יִם וַֽיִּמְתְּק֖וּ הַמָּ֑יִם שָׁ֣ם שָׂ֥ם ל֛וֹ חֹ֥ק וּמִשְׁפָּ֖ט וְשָׁ֥ם נִסָּֽהוּ׃

Exodus 15:25

(25) So he cried out to the LORD, and the LORD showed him a piece of wood; he threw it into the water and the water became sweet.
There He made for them a fixed rule, and there He put them to the test.

רש"י על שמות ט״ו:כ״ה:א׳

(א) שם שם לו. בְּמָרָה נָתַן לָהֶם מִקְצָת פָּרָשִׁיּוֹת שֶׁל תּוֹרָה שֶׁיִּתְעַסְּקוּ בָהֶם, שַׁבָּת וּפָרָה אֲדֻמָּה וְדִינִין (סנהדרין נ"ו):

Rashi on Exodus 15:25:1

(1) שם שם לו HERE HE MADE FOR THEM [A STATUTE AND AN ORDINANCE) — At Marah He gave them a few sections of the Torah in order that they might engage in the study thereof; viz., the sections containing the command regarding the sabbath, the red heifer and the administration of justice (Mekhilta d'Rabbi Yishmael 15:25; Sanhedrin 56b).

רש"י על שמות כ״א

(א) ואלה המשפטים. כָּל מָקוֹם שֶׁנֶּאֱמַר "אֵלֶּה" פָּסַל אֶת הָרִאשׁוֹנִים, "וְאֵלֶּה" מוֹסִיף עַל הָרִאשׁוֹנִים, מָה הָרִאשׁוֹנִים מִסִּינַי, אַף אֵלּוּ מִסִּינַי; וְלָמָּה נִסְמְכָה פָּרָשַׁת דִּינִין לְפָרָשַׁת מִזְבֵּחַ? לוֹמַר לְךָ, שֶׁתָּשִׂים סַנְהֶדְרִין אֵצֶל הַמִּקְדָּשׁ (מכילתא):

Rashi on Exodus 21

(1) ואלה המשפטים NOW THESE ARE THE JUDGMENTS — Wherever אלה, “these are”, is used it cuts off (פוסל) the preceding section from that which it introduces; where, however, ואלה “and these” is used it adds something to the former subject (i. e. forms a continuation of it). So also here: “And these are the judgments (i. e. these, also)”: What is the case with the former commandments (the עשרת הדברות)? They were given at Sinai! So these, too, were given at Sinai! (Mekhilta d'Rabbi Yishmael 21:1:1; Shemot Rabbah 30:3; cf. also Midrash Tanchuma, Mishpatim 3) If this be so, why is this section dealing with the “civil laws” placed immediately after that commanding the making of the altar? To tell you that you should seat (i. e. provide quarters for) the Sanhedrin in the vicinity of the Temple.,

חגיגה י״א ב:י״ט

עֲרָיוֹת שָׁאנֵי דְּאָמַר מָר גָּזֵל וַעֲרָיוֹת נַפְשׁוֹ [שֶׁל אָדָם] מְחַמְּדָתָן וּמִתְאַוָּה לָהֶם

Chagigah 11b:19

The Gemara answers: The halakha of forbidden sexual relations is different, for the Master said: Robbery and forbidden sexual relations are sins that one’s soul covets and lusts after. Therefore, we are concerned that one who has not properly studied these matters with his teacher will rule leniently for himself.

מועד קטן י״א ב:י״ג

וְהוּא סָבַר: אָדָם חָשׁוּב שָׁאנֵי.

Moed Katan 11b:13

The Gemara explains: But Mar, son of Rav Aḥa, maintains: An important person is different. Even if strictly speaking something is permitted, an important person must be more rigorous with himself, so that people learn not to take the halakha lightly.

בבא קמא ל׳ א:ט״ז-י״ח

ת"ר חסידים הראשונים היו מצניעים קוצותיהם וזכוכיותיהם בתוך שדותיהן ומעמיקים להן ג' טפחים כדי שלא יעכב המחרישה רב ששת שדי להו בנורא רבא שדי להו בדגלת אמר רב יהודה האי מאן דבעי למהוי חסידא לקיים מילי דנזיקין רבא אמר מילי דאבות ואמרי לה מילי דברכות:

Bava Kamma 30a:16-18

The Sages taught: The early pious people would conceal their thorns and their pieces of glass in their fields, and would dig to the depth of at least three handbreadths in order to bury them, so that they would not obstruct the plow. The Gemara relates: Rav Sheshet would toss his thorns into fire, so they would not cause damage to others. Rava would toss them into the Tigris [Diglat] River. Rav Yehuda says: One who wants to be pious should observe the matters of tractate Nezikin, so as to avoid causing damage to others. Rava said he should observe the matters of tractate Avot. And some say he should observe the matters of tractate Berakhot.
