No Court Left to Ask
Issurei Biah 11|Sefer Kedushah
A Question With Nowhere to Go
There was once a place to take a question nobody could answer.
The Torah’s laws of niddah and zivah require a kind of expertise that has to be housed somewhere. Days had to be counted, categories distinguished, and certain judgments made by people trained to make them. The Rambam opens this chapter by describing that arrangement. The Jews followed these laws as Scripture gives them when the Supreme Sanhedrin held sessions and included great sages familiar with the bloods. If a doubt arose for the lesser judges, they could ascend and ask, because the Torah had promised them this: if a matter of judgment is unknown to you concerning one type of blood or another, you shall ascend to the place that God shall choose.
Then the court stopped sitting.
What follows is a legal history of what a nation does when the authority to settle its hardest questions is gone. The law did not loosen, and it did not simply tighten by decree from above. The women of Israel took something upon themselves, and the Rambam writes it into the law of the land. And then, in the same chapter, he demolishes two other customs in language he almost never uses.
Where does he draw that line, and why there?
A Clock Attached to a Whole Life
See first how hard the original system is. It is very difficult to keep track of the counting of the dates, the Rambam writes, and many times doubts will arise. He means something structural. The Torah’s scheme distinguishes the days of niddah from the days of zivah, and the two carry different consequences, so a woman’s standing at any moment is a function of where she sits in a count. And the count does not begin at marriage, or at maturity. It begins at the very first discovery of bleeding in a life, even in a minor. The Rambam draws the consequence with flat arithmetic: a girl cannot become impure as a zavah until she is ten days old. Seven days of niddah from a discovery on the day she was born, then the three further days that would make her a zavah. Ten.
A clock attached to an entire lifetime, running continuously, with legal status depending on the count at every moment. That is what required a court.
By the era of the Sages of the Gemara, many doubts had arisen, both about the appearance of blood and about the reckoning of the pattern. The Rambam is unsparing about the second: it was not within the potential of all women to calculate the days of niddah and of zivah. That is not a verdict on character but on a system that had lost its central office.
So the Sages ruled stringently. They decreed that a woman treat all her days as days of zivah and every discovery of bleeding as zivah bleeding, out of doubt. The Maggid Mishneh explains that the Rambam left this ordinance unelaborated because it was a temporary measure, and points to Rabbi Yehudah HaNasi’s ordinance in the Talmud, that a woman who discovers bleeding wait six spotless days, or seven if the bleeding ran three consecutive days. Whichever category she was truly in, the count would cover it. That is the first response to a lost court: when you cannot tell which case you are in, you hold yourself to the stricter one.
Seven Days That Nobody Commanded
Then the chapter does something with almost no parallel in the Mishneh Torah. The next layer of severity is not legislated. It is accepted.
In addition, the Rambam writes, Jewish women accepted a further stringency upon themselves. Wherever Jews live, whenever a woman discovers bleeding, even a drop no larger than a mustard seed, even if it stops at once, even if it came during her days of niddah when the Torah would not require it, she counts seven spotless days and immerses on the night of the eighth. One day of bleeding, two, a full seven, longer: the same count a major zavah keeps, and only then is she permitted to her husband.
The Rambam extends it wherever the logic extends. Every woman who gives birth in the present age is treated as one who gave birth while a zavah, and counts her seven spotless days. In the era of the Geonim the days of so-called pure blood were abolished altogether, and from Babylon to Eretz Yisrael to Spain and North Africa any discovery of bleeding after childbirth starts the seven days again, even for a woman who had already counted and immersed. In France, he records, relations were still permitted then, as Talmudic law had allowed, and he does not condemn it: this matter is dependent on local custom.
The stringency reaches into the days before a marriage. A girl who is asked to marry and consents counts seven spotless days from her consent, on the possibility that she desired a man and released a drop without being aware of it. Whether she is a mature woman or a minor, the same. If she is marrying a Torah scholar she may marry at once and count afterward, because he will know she is forbidden and keep the restriction, though the Ra’avad and the Tur read the Rambam here as not accounting for the prohibition of seclusion.
Then the sentence that gives all of it legal weight. All of these matters are additional stringencies that have been practiced by Jewish women from the era of the Sages of the Talmud onward. One should never deviate from it.
Never deviate from what nobody commanded. What a people takes on honestly, and keeps, has become the law.
Where the Rambam Says Stop
Which raises the obvious question, and the chapter answers it with heat. If accepted severity becomes binding, is all severity good? The Rambam says no, twice, and softens neither one.
In certain places, he writes, the practice is that a woman treats herself as a niddah for seven days although her bleeding lasted a single day, and only then begins counting seven spotless days. This is not a proper custom. It is an error on the part of the one who ruled in this manner, and is not worthy of any consideration. One day of bleeding, then the seven spotless days, then immersion on the night following the eighth, and she is permitted to her husband.
The second one is harsher. In certain places, with support in responsa of some of the Geonim, a woman who gave birth to a son would not resume relations until forty days had passed, and one who gave birth to a daughter until eighty, even where bleeding was discovered only in the first seven. Those responsa, the Rambam says, are in error, and the practice in those places is of a heretical nature. They learned the interpretation from the Sadducees. It is a mitzvah to compel these people to remove it from their hearts and return them to the words of the Sages, who require only the counting of seven spotless days.
Hold those two rulings beside the paragraph before. A severity taken on by the whole people and kept for centuries: never deviate from it. A severity invented by a ruling that misreads a verse: an error, and worse, because it undermines the Oral Law, the only thing holding the verse’s meaning in place.
The chapter is equally careful about what stays pure. The laws of stains remain as they were, and a stain ruled pure is pure; the Rambam holds that a stain is not identical to a discovery of bleeding, though the Ra’avad disagreed and later authorities followed him. A miscarriage of a form the Sages ruled pure is still pure. A white or green secretion is pure. Blood from a wound, or released with urine, is pure. The stringency was about impure bleeding, and will not grow past its own subject.
All the Water in the World
Two halachot close the chapter, and they are the ones to carry away.
The first is where the change actually happens. A woman does not ascend from ritual impurity, and does not cease being considered an ervah, until she immerses in a mikveh that is halachically acceptable, with nothing intervening between her flesh and the water. If she washes in a bath, the Rambam says, even if all the water in the world passes over her, her state afterward is what it was before. An immersion taken during the seven spotless days is as though she had not immersed at all. On the seventh day, after sunrise, the immersion is valid even though it should not be done then, lest the day be nullified before nightfall.
The second is what the law asks of the husband, which is the half of these chapters people skip. During the seven spotless days he may not embrace her, even when both are clothed, may not draw close to her or touch her with so much as his little finger, and may not eat with her from one plate. The three household acts that carry intimacy, washing his face and hands and feet, pouring his drink, making his bed in his presence, she does not perform. These are decrees lest they come to sin, because relations remain punishable by kereit until she immerses.
And then, in the middle of all that distance, the chapter sets down one more line. It is permitted for a woman to adorn herself during her days of niddah, so that she does not become unattractive to her husband.
Humility Becomes Law, Misreading Becomes Heresy
Read the chapter end to end and a single test emerges. The Rambam is not sorting customs by how strict they are, but by whether they tell the truth about what the Torah says.
The seven spotless days are a real severity, and no verse requires them. The Rambam upholds them absolutely, because they were taken on in open acknowledgment of a doubt the people could no longer resolve, and kept universally for generations. The forty days after a son and the eighty after a daughter are also a severity, and the Rambam calls them heresy, because they acknowledge no doubt at all. They rewrite a verse, and the reading they import belongs to the sect that denied the Oral Law. A stringency born of humility becomes law. A stringency born of a misreading is an attack on the law wearing the law’s clothes.
The Alter Rebbe returns in the Tanya to a plain insistence: the deed is the main thing. Not the feeling about it, not the severity built around it. The deed. This chapter is that insistence in the form of a halacha. A woman may count and separate and wait, and until she immerses her standing has not moved, because it was never a function of how much she did. It was a function of one act.
The Baal Shem Tov’s devotion to immersion was famous among his students, and Chassidus reads the mikveh as bitul, self-nullification: the whole body under, nothing held out of the water, no part kept back. That is the halacha. Nothing may intervene between her flesh and the water, and a substance between the two voids the immersion. Partial does not count.
The Severity Nobody Asked You For
Most of the weight a person carries was never put there by anyone.
Sort the rules you actually live by into two piles. In the first are the disciplines you accepted with your eyes open, knowing the cost and taking it anyway. In the second are the ones that accumulated: standards nobody set, lines drawn in a frightened hour, weight added because carrying weight feels like seriousness. The Rambam’s chapter insists these are not the same kind of thing.
The first pile is binding. One should never deviate from it. A commitment genuinely accepted does not become optional when the mood that produced it passes.
The second pile is not devotion. Some of it is anxiety and some of it is a misreading, and the Rambam’s word for the worst version is error. Invented severity carries a cost people do not see. It teaches you that the work is measured by how much you deny yourself, when the work is one specific act, done or not done. Forty days of unnecessary waiting is not forty days of additional holiness. It is forty days taken from a husband and wife who were permitted to each other.
And then the harder half. All that counting arrives at water, and only water. A person can wash a situation for years without crossing the one threshold that changes anything. We do it with apologies that never become changed conduct, resolve that never becomes a commitment, learning that never becomes a set time. All the water in the world passes over you, says the Rambam, and your state afterward is what it was before.
There is a threshold. Washing is not it.
What the Separation Was Guarding
Stay with that last line, because it is easy to walk past.
The Rambam has just finished building a wall of separations. No embrace, even clothed. No touch, not with the little finger. Not one plate between them. And then: it is permitted for a woman to adorn herself during her days of niddah, so that she does not become unattractive to her husband.
A system built entirely out of distance stops to protect the attraction inside it. The separation is not there because the marriage is suspect. It is there because the marriage is what is being guarded, and a law that let the distance corrode what it guarded would have failed on its own terms.
The Lubavitcher Rebbe placed the laws of family purity at the center of what he asked of Jewish homes, and said a community building from nothing should build its mikveh before its synagogue. Not because water matters more than prayer. Because the water is where a Jewish home starts.
That is the measure to carry out of this chapter. A discipline honestly accepted, honestly bounded, honestly completed, with nothing invented on top of it and nothing held out of the water. Everything else is washing.
