Le Lévitique 15:28 Références de la Michna : Mishnah Nedarim & Mishnah Eduyot

וְאִֽם־טָהֲרָ֖ה מִזּוֹבָ֑הּ וְסָ֥פְרָה לָּ֛הּ שִׁבְעַ֥ת יָמִ֖ים וְאַחַ֥ר תִּטְהָֽר׃

Lorsqu’elle sera délivrée de son flux, elle comptera sept jours, après quoi elle sera pure.

Mishnah Nedarim

He may donate his terumah and his tithes with his consent. He may offer up for him the bird sacrifices of zavim and zavoth and the bird sacrifices of women after childbirth, sin-offerings and guilt-offerings. He may teach him midrash, halakhoth and aggadoth, but not Scripture, yet he may teach his sons and daughters Scripture And he may support his wife and children, even though he is liable for their maintenance. But he may not feed his beasts, whether clean or unclean. Rabbi Eliezer says: he may feed an unclean beast of his, but not a clean one. They said to him: what is the difference between an unclean and a clean beast? He replied to them, a clean beast, its life belongs to heaven, but its body is his own; but an unclean animal its body and life belongs to heaven. They said to him: The life of an unclean beast too belongs to heaven and the body is his own for if he wishes, he can sell it to a non-Jew or feed dogs with it.

Mishnah Eduyot

Rabbi Eliezer says: there are two instances of lenient rulings by Beth Shammai and strict rulings by Beth Hillel.The blood of a woman after childbirth who has not immersed herself, Beth Shammai says: [it is] like her spittle and her urine. But Beth Hillel says: it causes impurity whether wet or dry. However, they agree in the case of the blood of a woman who gave birth when she had non-menstrual discharge, that it causes defilement whether wet or dry.
