7:1-4Not Because of the Child
  • The blood of the throes. Bleeding with labor pains makes her a niddah in her days of niddah but leaves her pure in her days of zivah: the blood must come “from herself,” not because of a child. Only for a living birth, not a miscarriage. Later generations treated it as impure. (7:1)
  • Fourteen days, and the pain must hold. Up to fourteen days of bleeding with continuous pain before birth is blood of the throes; fifteen or more is zivah. If the pains stop and she is at ease for twenty-four hours after three days, she is a zavah. (7:1-2)
  • Difficulty near birth decides. Pain close to the birth attributes the bleeding to the birth; ease close to the birth does not. (7:3)
  • The day of birth. The day she gives birth always counts as a day of difficulty, even if it felt easy. A doubtful miscarriage after two days of bleeding leaves her status in doubt. (7:4)
RememberPain that belongs to a coming life is not counted as the mother's loss.
7:5-11Pure From This, Impure From That
  • Birth within zivah. She counts seven clean days, immerses at night and brings a zavah's offering and a childbirth offering; only then do the laws of pure blood apply. After a daughter she waits until the fifteenth night. (7:5-6)
  • Delayed immersion. If the bleeding never stops, pure blood does not apply. Once she has counted seven clean days, bleeding before she immerses does not change her status. (7:7-8)
  • A pregnancy within the pure days. Bleeding before a miscarriage within the eighty days is pure until the miscarriage; with twins she counts from the second. (7:9)
  • The count survives the birth. The throes or a birth during her seven clean days do not cancel them, and the Rambam counts those days, against the Ra'avad. “Pure from her zivah”: other impurities do not cancel the count. Only zivah bleeding does, and it costs only that day. (7:10-11)
RememberA setback of one kind does not erase progress of another.
7:12-24Every Permitted Day
  • 114 days. Two days of zivah, seven of niddah, two of zivah, fourteen of the throes, eighty after a daughter, seven of niddah and two of zivah: never three consecutive days in zivah. After the days of childbirth, bleeding begins new days of niddah regardless of earlier vesatot. (7:12)
  • One on, one off. A woman who bleeds every other day is permitted four nights in eighteen days; with two and two, the eighth, twelfth, sixteenth and twentieth. (7:13-14)
  • Three through seven. Three to six impure days alternating with as many pure ones leave her a permanent zavah after a few permitted days. A week and a week permits eighteen days in eighteen weeks, about a quarter. (7:15-20)
  • Eight and beyond. Eight and eight: fifteen days in forty-eight. Nine and nine: eight of every eighteen. Ten and ten, or a thousand and a thousand: as many permitted days as days of zivah. In practice, seven clean days are counted after any bleeding. (7:21-24)
RememberThe law does not give up on a hard pattern; it counts every day that can be hers.
