NIDAH 63 - Dedicated l'Iluy Nishmas Reb Aharon Dovid ben Elimelech Shmuel Kornfeld (Muncasz/Israel/New York), who passed away on 3 Av 5761, by his daughter, Shifra, and family. May his love for Torah and for Eretz Yisrael be preserved in all of his descendants.


1. The Gemara explains what happens if one of the later ingredients was rubbed on the blood before the first ones listed earlier in the Mishnah (see 62, #2 above).
2. The Mishnah lists symptoms that some women have that are a strong indication they are going to imminently receive their menstrual period.
3. The Mishnah discusses the status of the Taharos a woman dealt with when she had these symptoms (see #2 above).
4. The opinions of Rebbi Yosi and Rebbi Yehudah regarding when a woman is forbidden because she is anticipating her menstrual period.
5. The Mishnah discusses how a woman establishes and removes a time when she expects to see her period.


1. While there seems to be a contradiction between Beraisos in this case, the Gemara reconciles them by saying that all agree they must be applied in order at some point. Accordingly, if the first ones were done in order but after a later ingredient, the first ones still count as long as they are in the proper order, and the later ones must be redone.
2. Examples of these include bouts of coughing, sneezing, and stomach pains. If a woman has these symptoms before expecting her menstrual period three times in a row, she must suspect that she is about to receive her menstrual period and she is therefore forbidden to her husband at that time.
3. Tana Kama: If she generally sees imminently after the start of these symptoms, any Taharos she deals with during this time are considered impure. If she only sees at the end of this time, all Taharos she deals with during the beginning until the end of this time are considered pure.
4. Rebbi Yosi: The hour/s when she receives her period is when she is forbidden (if she consistently sees her period during this hour/s). Rebbi Yehudah: A woman is forbidden for either the entire day or night when she normally receives her period, regardless if her period usually arrives at the beginning or end of the day/night.
5. The general rule of the Mishnah is that a woman only establishes such a time if she sees her menstrual period three times in a row, and only takes away the suspicion of such a time when she does not see her period at that time three times in a row. However, she also must suspect that she will receive her period after a similar amount of days (from the beginning of her second to last period to when she received her most recent period), even if that has not been established three times.
