Niddah
Niddah (or nidah; ), in traditional Judaism, describes a woman who has experienced a uterine discharge of blood (most commonly during menstruation), or a woman who has menstruated and not yet completed the associated requirement of immersion in a "mikveh" (ritual bath). In the Book of Leviticus, the Torah prohibits sexual intercourse with a "niddah". The prohibition has been maintained in traditional Jewish law and by the Samaritans. It has largely been rejected by adherents of Reform Judaism and other liberal branches. In rabbinic Judaism, additional stringencies and prohibitions have accumulated over time, increasing the scope of various aspects of  niddah, including: duration (12 day minimum); expanding to prohibition against sex to include: sleeping in adjoining beds, any physical contact, and even passing objects to any male, including ones spouse; and requiring a detailed ritual purification process. Since the late 19th century, with the influence of German Modern Orthodoxy, the laws concerning "niddah" are also referred to as "taharat hamishpacha" (, Hebrew for "family purity"), an apologetic euphemism coined to deemphasize the impurity of the woman (a concept criticized by the Reform movement) and to exhort the masses by warning that niddah can have consequences on the purity of offspring. Etymology  and usage. "Niddah" has the general meaning of “expulsion” and “elimination”, coming from the root ndd, "to make distant" (the Aramaic Bible translations use use the root rhq, "to be distant"), reflecting the physical separation of women during their menstrual periods, who were “discharged” and “excluded” from society by being banished to and quarantined in separate quarters. Later in the biblical corpus, this meaning was extended to include concepts of sin and impurity, which may be related to ancient attitudes towards menstruation. Literally, the feminine noun "niddah" means "moved" (i.e. "separated"), and generally refers to separation due to ritual impurity . Medieval Biblical commentator Abraham ibn Ezra writes that the word "niddah" is related to the term "menadechem" (), meaning "those that cast you out". Hebrew Bible. The noun "niddah" occurs 25 times in the Masoretic Text of the Hebrew Bible. The majority of these uses refer to forms of uncleanliness in Leviticus. For example, in Leviticus, if a man take his brother's wife, then that is "uncleanness", "niddah." The five uses in Numbers all concern the red heifer ceremony () and use the phrase "mei niddah", "waters of separation". includes a single exhortation of Hezekiah to the Levites, to carry forth  the "niddah" (translated: "filthiness"), possibly idols of his father Ahaz, out of the temple in Jerusalem. Usage in Ezekiel follows that of Leviticus. Finally, the Book of Zechariah concludes with an eschatological reference to washing Jerusalem: "In that day there shall be a fountain opened to the house of David and to the inhabitants of Jerusalem for sin ("ḥaṭ’at") and for uncleanness ("niddah")" (). Rabbinic injunctions. The copious laws of "niddah" contained in the Jewish rabbinic writings are almost entirely made-up of "fences" (), or safeguards, built around the Torah. The general rule which applies is that a woman is clean  from the standpoint of the Torah until she feels uterine blood discharge from its source within her body. However, the rabbis have declared a woman to be unclean although she has not felt any discharge of blood, but has merely seen either a red or black blood stain on her body, or on her white garment or sheet, and which blood stain is larger in diameter than a fava bean (about 20 mm), in which case she must separate herself from her husband until she can complete seven clean days and can be purified in a ritual bath (mikveh). A  blood stain that is a dark brown color leaning towards the color of coffee and the color of chestnuts defiles a woman and renders her "niddah", on the condition that she feels its discharge. However, if she saw the same color while checking herself with an inspection cloth, but had not felt any discharge of blood, she is clean. Conversely, a vaginal discharge that is white in color, or either light yellow, green or blueish in color, do not render the woman "niddah". There are, yet, many other conditions that need to be met, by rabbinic ordinances, in order to  render uncleanness to a blood stain. The daughters of Israel have behaved stringently with themselves, insofar that even if they should see a drop of blood as a mustard grain, they would wait over it seven days of cleanness Although the Written Law () explicitly enjoins women to count seven days of cleanness (see "infra") 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. Application of the Torah. The Leviticus description of "niddah" is essentially composed of two parts: the ritual purity ("tumah and taharah") aspect "and" the prohibition of sexual intercourse aspect. Ritual purity aspect. The Biblical regulations of Leviticus specify that a menstruating woman must "separate" for seven days (). Any object she sits on or lies upon during this period is becomes a "carrier of tumah" ("midras uncleanness"). One who comes into contact with her "midras," or her, during this period becomes ritually impure () In addition, a man who  has sexual relations with her is rendered ritually impure for seven days—as opposed to one day of impurity for coming into contact with her or her "midras" (). While the purity laws still exist in theory, in modern times there is generally no practical consequence to becoming impure (as, e.g., the Temple in Jerusalem cannot be visited), so the laws have no practical expression. Some later rabbinic authorities encouraged (but did not require) avoiding the "midras" of the "niddah", as a remembrance for diasporic Jews so as to not forget the purity laws. This encouragement was only for the  Biblically prescribed seven-day period, not the five-day extension due to Rabbi Zeira's stringency. The Lubavitcher rabbi Menachem Mendel Schneerson discouraged abstaining from the "midras" of a "niddah" in modern times. Sexual relations. Leviticus further prohibits sexual intercourse with a woman who is in her "niddah" state. "And to a woman in her (state of) "niddah" impurity you should not come close (with intent to) reveal her nudity" (). The Torah concludes by imposing the punishment of "kareth" on both individuals (man and woman) if the prohibition is violated () This "issur" (prohibition) component of physical relations with the "niddah  is considered in full effect and mandatory for all children of Israel. Practical laws. Start of menstruation. According to rabbinical law, a woman becomes a niddah" when she is aware that blood has come from her womb, whether it is due to menstruation, childbirth, sexually transmitted disease, or other reasons. If menstruation began before she sees evidence of it, the rabbinic regulations regard her as not being "niddah" until she notices. Until this point, the regulations do not come into force. It is not necessary for the woman to witness the flow of blood itself; it is sufficient for her  to notice a stain that has indications of having originated in her womb; bloodstains alone are inadequate without such evidence, for example, if she finds a stain just after cutting her finger, she does not become a "niddah", as the blood is not obviously uterine. If she notices a bloodstain of uncertain origin, for example on her underclothing, there are a series of complicated criteria used by rabbinical law to determine whether she is "niddah" or not; the woman herself is not expected to know these criteria, and must seek the assistance of a rabbi. Duration of "niddah" status. According  to the Torah, the "niddah" period is 7 days; however, in Ashkenazi communities, the Rabbis added a stringency increasing the minimum duration period to 12 days. (See section "Seven days of cleanness" for differences in custom). The Biblical definition of "niddah" is any blood emission occurring within seven days from the beginning of the menstrual period. After this seven-day period, the woman may immerse in the mikveh immediately (if she has stopped menstruating). Any blood found after these seven days is considered abnormal ("zavah") blood and is subject to more stringent requirements, depending on the duration of said abnormal  blood flow. In the days of the Amoraim, because of possible confusion in determining when menstruation began and ended and hence whether blood was normal menstrual ("niddah") or abnormal ("zavah") blood, it became the accepted practice and practical halacha, that all women treat any emission as a continued abnormal flow ("zavah gedolah"—זבה גדולה), which requires counting seven abnormal-discharge-free days from the end of menstruation. This lengthening of the "niddah" period is known as Rabbi Zeira's stringency. All Orthodox and some Conservative authorities rule that these "seven clean days" must be observed. Practices during "niddah". In the Orthodox  Jewish community, women may test whether menstruation has ceased; this ritual is known as the "hefsek taharah". The woman takes a bath or shower near sunset, wraps a special cloth around her finger, and swipes the vaginal circumference. If the cloth shows only discharges that are white, yellow, or clear, then menstruation is considered to have ceased. If discharge is red or pink, it indicates that menstruation continues. If it is any other color, like brown, it is subject to further inquiry, often involving consultation with a rabbi. The ritual requires that the cloth used to perform this test is  first checked carefully to ensure that it is clean of any marks, colored threads, or specks; the cloth itself can be any clean white cloth, although there are small cloths designed for this ritual, known as "bedikah cloths" (meaning "checking"). In the Orthodox Jewish community, further rituals are practiced toward assurance regarding the cessation of the menstrual flow. After the "hefsek taharah", some women insert a cloth (or, in modern times, a tampon), consequently known as a "moch dachuk", for between 18 minutes and an hour, to ensure that there is absolutely no blood; this must be done carefully, as  it could otherwise irritate the mucous membrane, causing bleeding unrelated to menstruation. If there is any fear of irritation causing bleeding, a rabbi may waive this practice. The "bedikah" is repeated each morning and evening of the seven days after the end of menstruation. Another tradition is the wearing of white underwear and use of white bedding during this period; conversely, the rest of the time, when not counting the "seven clean days", some women who suffer from spotting deliberately use coloured underwear and colored toilet paper, since it is only when blood is seen on white material that it  has any legal status in Jewish law. When not during their seven "clean" days, all women are advised to wear colored undergarments, for this reason. It is furthermore strongly recommended that women make an effort to refrain from looking at the toilet paper after wiping to avoid possible resultant questions. Physical contact during "niddah". As with most forbidden relationships in Judaism, all physical contact in an affectionate or lustful manner is rabbinically forbidden when a woman is in her "niddah" status. Such contact is forbidden whether or not the man and woman are husband and wife. In the case of  husband and wife, however, the sages added on extra restrictions, including touch that is not in an affectionate or lustful manner, passing of objects even without touching, and sleeping in the same bed; these restrictions are to avoid the risk of leading to sexual contact. These laws are termed "harchakot", meaning "the laws of separation," and imply the prohibitive rules regulating the passing of objects from hand to hand, as well as to taking distinctive measures used to remind them of their separation, such as placing some object at the dinner table which is not ordinarily placed there. The laws  of separation ("harchakot") are derived from a biblical command: "You shall not approach a woman to uncover her nakedness so long as she is separated for her [menstrual] uncleanness" (). Some have suggested that by physically distancing oneself from his spouse there is an enhanced need for relationships to develop in non-physical ways, such as emotional and spiritual connections. Some Conservative poseks are considerably more lenient in reference to the "harchakot" than Medieval or contemporary Orthodox authorities. In a responsum written in the Committee on Jewish Law and Standards of the Rabbinical Assembly, Miriam Berkowitz ruled that the ""harchakot" are  to be observed as much as possible, but left up to the discretion of each couple". In another responsum for the committee, Susan Grossman stated that touching that would be appropriate between siblings is permissible. The classical regulations also forbid sexual relations on the day that a woman expects to start menstruating; there are three days that fall under this regulation, known as the "veset", namely the same day of the month as her previous menstruation began; the day exactly 30 days after the previous menstruation started; and the day that is the usual interval from the end of her  previous menstruation. If the woman is not actually menstruating during a "veset" day, then there are certain circumstances wherein sexual activity is permitted according to most authorities, for example, if a woman's husband is about to travel, and will return only after menstruation has begun. Seven days of cleanness. When blood from a menstruant ("niddah") has ceased altogether, shortly before sunset she performs on herself a "cessation of uncleanness", known by its Hebrew euphemism "hefseq be-ṭaharah" ( = lit. "cessation of purification"), during which time she checks herself to verify that all uterine bleeding has indeed stopped. This is  done by bathing, and, afterwards, inserting a clean piece of white cotton or linen cloth within her vagina and examining it after swiping the area inside, followed by leaving in that place a snugly fitting cotton wad for the duration of about 20 minutes (preferably during the evening twilight). When there are no signs of blood, the woman begins counting seven days of cleanness on the following day, during which seven days she is still prohibited to have any physical contact with her husband. During each of the seven days, the woman checks herself once in the morning and once  in the evening, by using a soft and white, absorbent cotton cloth. In Sephardic Jewish tradition, a woman who has had no physical contact with her husband within the 72 hr. period (3 days) prior to the start of her menstruation, she is permitted to immediately conduct the "hefseq be-ṭaharah" (see "supra") after all uterine bleeding has stopped, and, on the following day, she begins to count seven days of cleanness, which culminate in an immersion. Differences in custom, however, exist between the Ashkenazim and the Sephardic Jewish communities as to when to begin the counting of seven days  of cleanness if she cohabited with her husband within those 72 hours (three days) prior to her seeing blood. For the Sephardic Jewish community, waiting four days before beginning to count seven days of cleanness only refers to when there were conjugal affairs between a man and his wife, leading up to her menstrual period. If, however, there was no sexual intercourse between the couple in the days leading up to her menstrual cycle, and, subsequently, there was no fear of her body discharging of her husband's copulative seed that had been mixed with her menstrual blood, there is  no need for her to wait four days, but she may presently begin her "hefseq be-ṭaharah" (see "supra"), followed by counting seven days of cleanness. Another factor used to determine when to begin the counting of seven clean days (among Sephardic Jews) is that, had the woman merely found on her an unclean blood stain (where there was no sensation of any active blood flow), after concluding that all such sightings have stopped, she can begin to count seven days of cleanness after two days have passed since the last time she cohabited with her husband. However, among Ashkenazim , even if a woman merely saw an unclean blood stain, when the blood has ceased to appear, she waits 5 days before beginning to count her seven days of cleanness. Maimonides mentions a former custom where the menstruants of some Jewish communities would wait a standard 7 days before beginning to count seven days of cleanness, even if the woman had seen blood for only one or two days. This custom, though widely practised in the 20th century among the Jews of Yemen, Djerba, parts of Morocco, as also with a few families in Baghdad, was later rejected and abandoned  by many, as Maimonides calls it an errant practice. Niddah and fertility. Because the night that the woman ritually traditionally immerses is about 12 days after menstruation began, it often coincides with a woman's ovulation, and thus improves the chances of successful conception if sexual relations occur on that night. However, for certain women, this period extends far past the date of ovulation, and in combination with the ban on sexual relations during the "niddah" state, effectively results in the woman being unable to conceive, a situation sometimes called "halachic infertility". In the case of this effective infertility, rabbis  try on a case-by-case basis to relax halakhic strictures in order to facilitate conception. There have been some calls within Orthodox Judaism for the custom to be modified so that the time between the end of menstruation and the end of "niddah" is shorter for these women. Another suggestion is to take hormone tablets to lengthen the ovulation cycle. Checking by bedikah. The "bedikah" cloth or "checking cloth", called an "eid" ["witness"] in Hebrew, is a clean piece of white cloth used in the process of purifying a "niddah". It is used by observant Jewish women to determine  whether they have finished menstruation. The cloth is inserted into the vagina, and if no blood is found, the woman may start counting the seven blood-free days. On each of these days, she performs this examination in the morning and in the later afternoon before sunset. If no blood is found, she may go to the "mikveh" on the eighth evening after nightfall, and then engage in intercourse with her husband. Such cloths are about two by four inches, and are available at local Judaica stores, the local mikveh, stores in Orthodox neighborhoods in Israel, or may be cut  from clean all-white soft cotton or linen fabric. This practice is also occasionally used by Jewish men to check if he has gotten blood on himself from his wife after intercourse to determine whether she menstruated during intercourse. Immersion in water. After a woman has counted seven days of cleanness (see "supra"), she is then required to immerse in a ritual bath ("mikveh") that has been constructed in accordance with the Jewish laws of ritual purity. After concluding her seven days of cleanness, she is not allowed to immerse during the daytime, even on the eighth or ninth days , because of a rule introduced on account of her daughter's immersion () and which was enacted for the sake of conformity, so that the daughter will not see her mother immerse during the daytime and wrongly presume that it was her mother's seventh day of counting, and think that it was alright to immerse on the seventh day before nightfall, without realizing that her mother had already concluded her seven clean days. This enactment, therefore, was to prevent an occasion for miscalculation and stumbling. Even if a woman has no daughter, this rule of immersing only in the night  still applies, as the Sages did not make any distinction, but have prohibited all women from immersing themselves during daylight hours of the eighth day, or of any day. Under extenuating circumstances, however, the rabbis have also permitted to immerse in the day, after fully completing seven days of cleanness. There are differing customs about how many immersions are performed at each visit to a "mikveh". It is the custom of many in the Orthodox community to immerse at least twice. Accordingly, they would immerse, recite the blessing, then immerse again. The other opinion states that like other commandments, here  too the blessing should be recited before performing the commandment. Immediate preparation for a "mikveh" includes a bath or shower wherein every part of the body (including the ears and underneath the nails) is thoroughly washed; plus other routine hygiene practices which include trimming fingernails and toenails, brushing and flossing the teeth, and combing the hair. Prior to every immersion, the woman is required to inspect herself to make sure that there is nothing clinging to her skin and hair that would obstruct the water from making contact with it during her actual immersion, or what is known as "ḥaṣīṣah  = interposing objects" (e.g. clay, dough, paint, gum resin, etc.). At the "mikveh" itself, a female attendant is present to make certain that the woman immerses herself fully, including her hairs. Though that is the attendant's foremost duty, she may also help by checking a woman's back or answer questions regarding proper ritual protocol. Newlyweds. According to all Orthodox authorities, the first time a virgin has intercourse, she also becomes "niddah" as a result of her "dam betulim" (Hebrew: "hymenal blood flow"). This is observed even if no blood was discovered. However, a bride counts only four days  before performing a "hefsek taharah" (Hebrew: lit. pause of purity), instead of the usual five. The "hefsek taharah" simply entails a woman checking herself to make sure that all uterine bleeding has stopped, by inserting a piece of inspection cloth within her vagina and having it come out clean, in order to begin on the following day her seven days of cleanness. Some Conservative authorities rule that a woman is not a "niddah" in such a case unless uterine bleeding is observed. Privacy of the niddah process. Out of "tzniut" (Hebrew for "modesty"), many Orthodox Jews and some Conservative Jews  follow a custom of keeping their times of "niddah" secret from the general public. Conservative Judaism. Conservative Judaism authorities teach that the laws of family purity are normative and still in force, including the requirement to refrain from sexual relations during "niddah", yet there is a difference of opinions over how much other strictures need to be observed, such as whether there should be complete prohibition on any touching during "niddah" and whether women are required to count seven "clean" days before immersing in the "mikveh". In December 2006, the Rabbinical Assembly's Committee on Jewish Law and Standards passed  three responsa discussing the extent of Biblical requirements and continuing applicability of rabbinic prohibitions concerning niddah for Conservative Jews. Each responsum advocated different standards of observance; three responsa were passed as majority opinions - one by Susan Grossman and one by Avram Reisner, the third responsum, by Miriam Berkowitz. The majority of orthodox rabbis contend that the seven days of cleanness still apply to all menstruant women today, even though it is only a rabbinic injunction. According to two lesser opinions representing the movement of Conservative Judaism, one by Grossman and the other by Reisner, whose views are not shared by  orthodox Jewish circles, the "seven clean days" need not be observed today and women may immerse and resume sexual relations after seven days from the beginning of menstruation, or after its cessation, if it lasts longer than seven days. Grossman and Berkowitz ruled that women may rely on their own discretion about when menstruation has ended, and need not routinely engage in "bedikah" as described above. Despite the official stance, the practices related to family purity have often not been widely followed by Conservative Jews. However, in an issue of the "United Synagogue Review" that focused on issues of "mikvah  and niddah" (published in conjunction with the passing of the responsa mentioned above, in Fall/Winter 2006), Rabbi Myron S. Geller, a member of the Committee on Jewish Law and Standards, wrote about an upswing in the observance of the laws of family purity within the Conservative Jewish community: Conservative Judaism has largely ignored this practice in the past, but recently has begun to reevaluate its silence in this area and to consider the spiritual implications of mikvah immersion for human sexuality and for women. Reform Judaism. Reform Judaism and other liberal denominations have largely rejected many of the rituals  and prohibitions associated with menstruation, particularly the use of a "mikveh".
