Niddah 4:7 - 5:1

כל אחד עשר יום – after the seven days of menstruation/Niddah.

בחזקת טהרה – and she doesn’t have to examine herself, for it is a Halakha transmitted to Moses at Sinai (albeit not written down) that there is no distinction between one menstruating cycle to another that is less than eleven days.

ישבה לה ולא בקדה – our Mishnah is deficient and should be read as follows: During the days of her menstruating period it requires examination. If she sat and did not examine herself inadvertently, or she was under constraint, or willfully didn’t examine herself, she is [ritually] pure/clean.

הגיעה שעת וסתה ולא בדקה – even though she examined herself afterwards and found herself to be pure/clean, since she didn’t examine herself at the time of her period, that she is impure/unclean, for her menstruation comes at its [appropriate] time.

במחבא (in hiding) – on account of robbers or an army that comes came to the city. But the Halakha is not according to Rabbi Meir.

אבל ימי הזב והזבה – the seven clean days that she needs to count.

ושומרת יום – as for example, that she sees [blood] one day or two days during the days of her flux, she does not count other than one day in cleanliness and she ritually immerses [herself] in the evening and is pure/clean to her husband.

הרי אלו בחזקת טומאה – since her fountain was opened up and she saw it (i.e., blood) today, even though it is within the eleven [days], she is on the morrow in the presumption of impurity/uncleanness.

יוצא דופן – a woman [whose womb] they opened through a drug and they removed the fetus and then she healed.

אין יושבין עליו ימי טומאה – seven [days] for [the birth of] a male and fourteen [days] for a female.

וימי טהרה – she does not have blood of purity.

ואין חייבין עליו קרבן – of a child-bearing mother, as it is written (Leviticus 12:2): “When a woman at childbirth bears a male, [she shall be impure seven days; she has be impure as at the time of her menstrual infirmity],” until she gives birth from the place where she emits a secretion at coition.

רבי שמעון אומר הרי זה כילוד (like one born naturally) – as it states (Leviticus 12:5): “ If she bears a female, [she shall be impure two weeks as during her menstruation, and she shall remain in a state of blood purification for sixty-six days],” to include that which goes for from the side (i.e., delivered by Caesarean section). But the Halakha is not according to Rabbi Shimon.

כל השנים מיטמאות – as a menstruating woman/נדה from when the blood goes out from the interior of the womb where the menses are discharged and reached the vagina/בית החיצון , but even though the enclosures of the womb preserved it and it did not pass outwards. As it is written (Leviticus 15:19): “[When a woman has a discharge,] her discharge being blood from her body/דם יהיה זבה מבשרה,” it teaches that she defiles even though it is still within her body,” and the vagina/בית החיצון is called the place where the limb threshes (i.e., euphemism for sexual contact) at the time of sexual intercourse.

אינן מטמאין עד שתצא טומאתן לחוץ – as is written concerning a person with gonorrhea/בזב (Leviticus 15:2): “When any man has a discharge issuing from his member/איש איש כי יהיה זב מבשרו, [he is impure],” until his flux leaves from his flesh, but regarding someone with a [nocturnal] emission, it is written (Leviticus 15:16 – the printed edition incorrectly lists chapter 22): “When a man has an emission of semen/ואיש אשר תצא ממנו שכבת זרע, [he shall bathe his whole body in water and remain impure until evening].”
