שַׁבַּ֨ת שַׁבָּת֥וֹן הוּא֙ לָכֶ֔ם וְעִנִּיתֶ֖ם אֶת־נַפְשֹׁתֵיכֶ֑ם בְּתִשְׁעָ֤ה לַחֹ֙דֶשׁ֙ בָּעֶ֔רֶב מֵעֶ֣רֶב עַד־עֶ֔רֶב תִּשְׁבְּת֖וּ שַׁבַּתְּכֶֽם׃ (פ)
É um Shabat de descanso para vós, e afligireis as vossas almas, no nono dia do mês à tarde; de tarde até a tarde guardareis o vosso Shabat." {פ}
Zohar
When Yod departs from Wav-Daleth through the sins of the world, the nakedness of all is found, on this it is written (Leviticus 18:7) "the nakedness of your father [...] you shall not reveal". And when Yod-Wav-Daleth departs from He-Aleph, on this it is written "the nakedness of your mother you shall not reveal, she is your mother, you shall not reveal her nakedness". Your mother she is for sure, (Proverbs 2:3) "because you will call Understanding (Bina) "mother" (אם) etc".
