Zavah
In Jewish ritual law, a zavah (Hebrew זבה, lit. "one who[se body] flows") is a woman who has had vaginal blood discharges not during the usually anticipated menstrual cycle, and thus entered a state of ritual impurity. A man who has had similar abnormal discharge from his genitals is known as a zav. In the realm of tumah and taharah, the "zavah" has the ability to create a midras, (, , ) and to make unclean for a seven-day period - a man who conducts sexual intercourse with her. Additionally, the "zavah" and her partner are liable to "kareth" for willfully engaging  in forbidden sexual intercourse. Hebrew Bible. Torah sources for the "zavah" are sourced in the book of Leviticus (, ). According to textual scholars, the regulations concerning childbirth,() which have a similar seven-day waiting period before washing, and the sin and whole offerings, were originally suffixed to those concerning menstruation, but were later moved. Although the "zavah" regulations clearly have a sanitary benefit in the light of modern medical knowledge, Biblical scholars see these regulations as having originally derived from taboos against contact with blood and semen, because they were considered to house life and were consequently considered sacred; the seven -day period is thought to exist to ensure that the abnormality has genuinely ceased, the sin offering is considered to have originally been made as an apology for violating the taboo. In rabbinic literature. According to the Jerusalem Talmud, the eleven-day period between each [monthly] menstrual cycle is "Halakha LeMoshe MiSinai". This has been explained by Maimonides to mean that seven days are given to all women during their regular monthly menstrual cycle, known as the days of the menstruate (Hebrew: "niddah"), even if her actual period lasted only 3 to 5 days. From the eighth day after the  beginning of her period (the "terminus post quem", or the earliest date in which they begin to reckon the case of a "zavah"), when she should have normally concluded her period, these are days that are known in Hebrew as the days of a running issue (Hebrew: "zivah"), and which simply defines a time (from the 8th to the 18th day, for a total of eleven days) that, if the woman had an irregular flow of blood for three consecutive days during this time, she becomes a "zavah gedolah" and is capable of defiling whatever she touches, and especially whatever  object she happens to be standing upon, lying upon or sitting upon. If blood flows or issues during that short window when it is expected not to, that, then, is an irregular flow. Only in such cases of irregular sightings of blood would the woman require seven days of cleanness before she can be purified, according to the Written Law of Moses (). Although the Written Law explicitly enjoins women to count seven days of cleanness when they have seen irregular blood sightings (the irregularity occurring only from the eighth day of the start of her regular period and ending with  the conclusion of the eighteenth day), the Sages of Israel have required all women who have experienced even their regular and natural purgation to count seven days of cleanness before they can be purified. Section::::"Zavah ketanah". The woman, within an eleven-day window of the completion of her base seven-day "niddah" period (and her typical immersion in the mikveh) notices an abnormal blood discharge. This one time discharge deems her a "zavah ketanah" (minor zavah) and brings the requirement for her to verify that the next day will show no discharge. Provided the next day is clean, her immersion  in the mikveh prior to sunset makes her "tahor" (pure) after sunset. Section::::"Zavah gedolah". In the "zavah gedolah" (major zavah) scenario, the woman, within an eleven-day window of the completion of her base seven-day "niddah" period (and immersion in the "mikveh") notices an abnormal blood discharge. If the next day another discharge is noticed, followed by yet another discharge on the third consecutive day, she is deemed a zavah gedolah. She is then required to count seven clean days, immerse in a mikveh on the seventh day and bring a "korban" on the eighth. Other laws. A female  must be at least ten days old to be eligible for zavah status. According to the Talmud, the law of "zavah" is applicable if the discharge in question had happened (at least) three times over three consecutive days. The Sifra stipulates that the "zavah" is required to immerse in a spring (as opposed to the standard "mikveh" bath) to obtain "taharah" (purification). The "zavah" is commonly known as one of four types of "tumah" that are required to bring a sacrifice post the purification process. The "korban" consists of both a sin offering and a "whole offering", each involving a  dove. Viewed as Divine punishment. Obadiah ben Jacob Sforno reasons that the "zavah gedolah" state is a divine consequence to alert the woman from acting in a manner comparative to Chava (Eve). This unpleasant consequence is implied by God's message to Chava in the verse "I will increase and multiply your discomfort" (Genesis 3:16), with the seven-day waiting period intended to allow a spirit of repentance and purity to enter her will. Her bringing of a dual sacrifice, the "Chatat" and "Olah", are to rectify her negative action and thought, respectively. Targum Yonathan describes the "zavah" state as  a divine consequence to a woman who neglects the requirement to take adequate precautions involving the laws and nuances of menstrual impurity. In modern Judaism. Due to the destruction of the Temple in Jerusalem, Judaism regards the sacrificial regulations as being in abeyance; rabbinical tradition subsequently differentiated less between the regulations of "zavah" and those for "niddah". In Orthodox Judaism nowadays, zavah (an abnormal discharge) and niddah (healthy menstruation) are no longer distinguished. A menstruating woman (niddah) is required to wait the seven additional clean days that she would if she were a zavah. Conversely, Reform Judaism regards such regulations  as anachronistic; adherents of Conservative Judaism take a view somewhere between these views, with opinions in favor of returning to the Biblical distinction between "niddah" (ending seven days from the beginning of a normal menstrual period) and "zavah" (ending seven days after the end of an abnormal discharge).
