Sefer Kedushah · Niddah and zivah once the Sanhedrin no longer sat: the Sages' ruling out of doubt, the seven spotless days women accepted, what remains pure, the two customs the Rambam strikes down, and the single act that changes status.
7
Spotless days, then immersion
10
Days old before a zavah is possible
11:1-3The Court That Could Answer
- Scriptural law assumed a court. The laws of niddah, zivah and childbirth were followed as Scripture gives them while the Supreme Sanhedrin sat and included great sages familiar with the bloods; a doubt could be carried up to them (11:1)
- The verse that authorized it. "If a matter of judgment is unknown to you concerning one type of blood or another," you ascend to the place God shall choose, meaning the Temple in Jerusalem (11:1)
- A count that can begin at birth. The reckoning starts at the first discovery of bleeding in a life, even in a minor; hence a girl cannot become impure as a zavah before she is ten days old, seven of niddah plus three (11:2)
- The Sages' ruling out of doubt. Because not all women could calculate the days of niddah against the days of zivah, the Sages decreed that every day be treated as a day of zivah and every discovery of bleeding as zivah bleeding (11:3)
RememberThe hardest cases once had an address. When the court stopped sitting, the doubt itself became the operating rule.
11:4-10The Stringency Women Accepted
- Seven spotless days for any discovery. Jewish women accepted that wherever Jews live, even a drop the size of a mustard seed that stops at once, even falling in her days of niddah, is followed by seven spotless days and immersion on the night of the eighth (11:4)
- Childbirth in the present age. Every woman who gives birth is treated as one who gave birth while a zavah; the Geonim abolished the former "days of purity," so any bleeding after a birth starts the seven days again (11:5-6)
- Where custom still governs. The Rambam records that in France relations were permitted during those former pure days as Talmudic law had allowed, and rules that the question is dependent on local custom (11:7)
- A bride counts from her consent. A girl asked to marry who consents counts seven spotless days from that consent, lest she desired a man and released a drop unawares; one marrying a Torah scholar may marry at once and count after, since he will keep the restriction (11:9-10)
RememberNo verse commands the seven spotless days. The Rambam still writes: these are stringencies Jewish women accepted, and one should never deviate from them.
11:11-15What Stays Pure, and What Is Error
- Stains keep their old rules. No new custom applies: a stain ruled pure is pure, and a stain ruled impure requires counting seven days after the day of its discovery even when too small to raise concern for zivut, "for the discovery of a stain is not identical with the discovery of bleeding" (11:11)
- Still pure today. A miscarriage of a form the Sages ruled pure, a white or green secretion, a red mass of flesh unaccompanied by bleeding, blood from a wound, and blood released with urine. Only shades of actual blood were all made impure (11:12-13)
- First custom struck down. Treating oneself as a niddah seven days when the bleeding lasted one, and only then counting seven spotless days, "is not a proper custom," but an error by the one who ruled it, unworthy of any consideration (11:14)
- Second custom struck down. Waiting forty days after a son or eighty after a daughter when bleeding appeared only in the first seven is "of a heretical nature," learned from the Sadducees; it is a mitzvah to compel its removal and return people to the Sages' seven days (11:15)
RememberSeverity is not automatically piety. A stringency that admits a doubt becomes law; a stringency that rewrites a verse the Rambam calls error, and worse.
11:16-19Only the Water, and the Distance
- Nothing but a mikveh. She does not ascend from impurity, and does not cease being an ervah, until she immerses in an acceptable mikveh, spring or sea with nothing intervening between her flesh and the water. Washing in a bath leaves her exactly as she was (11:16)
- Immersing inside the count. An immersion taken during the seven spotless days is as if she had not immersed at all, since the days are not complete (11:17)
- The distance laws. Through the seven spotless days he may not embrace her even when both are clothed, may not draw close or touch her with so much as his little finger, and they do not eat from one plate; relations remain punishable by kereit until she immerses (11:18)
- Three acts withheld, one permission given. She does not wash his face, hands and feet, pour his drink, or spread his bed in his presence; all other household work is permitted, and she may adorn herself in her days of niddah so that she does not become unattractive to her husband (11:19)
RememberAll the water in the world passing over her changes nothing. And a chapter built entirely of distance ends by protecting the attraction inside it.
