וְהָיְתָ֥ה לָכֶ֖ם לְחֻקַּ֣ת עוֹלָ֑ם בַּחֹ֣דֶשׁ הַ֠שְּׁבִיעִי בֶּֽעָשׂ֨וֹר לַחֹ֜דֶשׁ תְּעַנּ֣וּ אֶת־נַפְשֹֽׁתֵיכֶ֗ם וְכָל־מְלָאכָה֙ לֹ֣א תַעֲשׂ֔וּ הָֽאֶזְרָ֔ח וְהַגֵּ֖ר הַגָּ֥ר בְּתוֹכְכֶֽם׃
Et ceci sera pour vous une loi perpétuelle: au septième mois, le dixième jour du mois, vous mortifierez vos personnes et ne ferez aucun ouvrage, soit l’indigène, soit l’étranger séjournant parmi vous.
Yesod Mora VeSod HaTorah
Pay attention and contemplate that all the mitzvot that are fundamental or dependent on a specific matter or are mentioned or received traditions are positive or negative commandments explicitly stated or derived from their roots. Their secret is in the negative commandment, as it is written: "The children of Israel shall keep the Sabbath, to observe the Sabbath" (Exodus 31:16). Sabbath observance is not an action but rather refraining from action and resting from it. As it is written: "And He rested on the seventh day from all His work" (Genesis 2:2), meaning to prepare before the Sabbath so that no work is done on that day. Similarly, it is written: "You shall afflict your souls" (Leviticus 16:29), and the meaning is to not indulge in eating and drinking, for affliction transforms pleasure. And likewise, it is written: "And you shall sanctify yourselves, and you shall be holy" (Leviticus 20:7), meaning do not defile your souls by consuming anything abhorrent and corrupt in its origins. And the Nazirite, who shall not drink wine, is deemed holy.
