In Judaism, ritual washing, or ablution, takes two main forms. Tevilah () is a full body immersion in a mikveh, and netilat yadayim is the washing of the hands with a cup (see Handwashing in Judaism).
References to ritual washing are found in the Hebrew Bible, and are elaborated in the Mishnah and Talmud. They have been codified in various codes of Jewish law and tradition, such as Maimonides' Mishneh Torah (12th century) and Joseph Karo's Shulchan Aruch (16th century). These practices are most commonly observed within Orthodox Judaism. In Conservative Judaism, the practices are normative, with certain leniencies and exceptions. Ritual washing is not generally performed in Reform Judaism.
Hebrew Bible The Hebrew Bible requires immersion of the body in water as a means of purification in several circumstances, for example: And when the zav is cleansed of his issue, then he shall number to himself seven days for his cleansing, and wash his clothes; and he shall bathe his flesh in running water, and shall be clean.
There are also references to hand-washing in Leviticus 15:11, "All those whom the one with the discharge touches without his having rinsed his hands in water shall wash their clothes and bathe in water and be unclean until the evening." and in Psalms 26:6, "I wash my hands in innocence, and walk around Your altar, O LORD."
Priests were required to wash their hands and feet before service in the ritual sites:
Washing the hands
According to halakha or custom, the hands are washed several times. These include before and after eating a meal with bread, upon waking in the morning, after using the toilet, before eating karpas in the Passover seder, and before prayer. On some occasions, the water must be poured from a cup; on others, it may be delivered by any means, such as a faucet. A blessing is recited on some occasions.
Full-body immersion
Depending on the circumstances, such ritual bathing might require immersion in "living water"—either a natural stream or a mikveh, a specially constructed ritual bath connected directly to a natural source of water such as a spring. There are several occasions on which biblical or rabbinical regulations require immersion of the whole body. For example, the impurity of zav is unique in that it cannot be purified by immersion in a normal mikve but requires immersion in a spring of living water.
This article discusses immersion requirements in Rabbinic Judaism and its descendants. Other branches of Judaism, such as Haymanot, have substantially different practices, including requiring an actual spring or stream.
Current practice Occasions on which full-body immersion is currently practiced include: After a woman's niddah period concludes following menstruation or other uterine bleeding, she must immerse and only then is permitted to resume sexual relations with her husband.Babylonian Talmud, tractate Shabbath 64b. This practice remains the principal use of contemporary mikvehs. It is fully observed in Orthodox Judaism, and normative in Conservative Judaism. Some Orthodox men immerse after having a seminal discharge (keri).Although the Shulchan Aruch (OC 88) rules that they repealed the requirement of this immersion, it is still considered a pious practice to continue to observe it. In Orthodox Judaism, there is a widespread minhag for men to immerse themselves on the day before Yom Kippur, and many do so before the Three Pilgrimage Festivals and before Rosh Hashanah. Many also immerse themselves before the Shabbat, and many (primarily Hasidic Jews) do so daily before morning prayers. A convert to Judaism must immerse. Taharah, ("Purification"), the ritual washing and cleansing, and immersion in a mikveh according to many customs, of a Jew's body prior to burial Prior to ascending the Temple Mount (by those Orthodox or Masorti authorities who permit ascending the Temple Mount) In Hassidic Judaism, men regularly shower daily before immersing in the mikvah before prayer each morning.
Past practice
Bodily fluids and skin conditions
The Torah prescribes rituals addressing the skin condition known as tzaraath and unusual genital discharges in a man or woman (Zav/Zavah), which required special sacrifices and rituals in the days of the Temple in Jerusalem including immersion in a mikveh.
The practice of checking for tzaraath fell out of use with the destruction of the Temple in Jerusalem and the end of sacrificial rites. However, each of the other requirements remains in effect to some extent in Orthodox Judaism and (to a lesser degree) in Conservative Judaism.
Zavah A woman experiencing uterine blood, not part of normal menstruation, was classified as a zavah in the days of the Temple in Jerusalem and remained in a state of ritual impurity for seven days before immersion. Today, the law of zavah remains in effect in Orthodox Judaism, in two respects. Due to extreme conditions in Roman Palestine in the time of the Amoraim, women's periods became irregular, and women became unable to determine whether or not their discharges were regular (niddah) or irregular (zavah). As a result, women adapted a stringency combining the niddah and zavah periods, refraining from intercourse and physical contact with their husbands for seven days of the zavah period following menstruation, for a total of approximately 12 days per month, which Orthodox women continue to observe today. The laws of zavah are also applied, as in Biblical times, to uterine blood discharges outside regular menstruation. Such circumstances are often interpreted leniently, however, and rabbinic stratagems have been devised to lessen their severity. Women experiencing irregularities (droplets) are sometimes advised to wear coloured underwear to mitigate the detectability of evidence of zavah status and hence a need to determine that a woman is a zavah.
Keri
Men experiencing a seminal discharge, including through regular marital intercourse, were prohibited from entering the Temple in Jerusalem and required to immerse in a mikveh, remaining ritually impure until the evening. The Talmud ascribes to the Great Assembly of Ezra a Rabbinic decree imposing further restrictions on men ritually impure from a seminal discharge, including a prohibition on studying Torah and from participating in services.
Maimonides wrote a responsum lifting the decree of Ezra, based on an opinion in the Talmud stating that it had failed to be observed by a majority of the community and the Jewish people found themselves unable to sustain it. However, Maimonides continued to follow the Keri restrictions as a matter of personal observance. Since then, observance of the rules of Keri and hence regular mikveh use by men fell into disuse in many communities. Hasidic Judaism, however, revived the practice of regular mikveh use, advocating regular daily mikveh use as a way of achieving spiritual purity. The growth of Hasidic Judaism resulted in a revival of mikveh use by men. In addition, some Sephardic and Mizrahi communities continued to observe the rules of keri throughout.
Contact with an animal carcass
According to Leviticus, anyone who comes into contact with or carries any creature that had not been deliberately killed by shechita was regarded by the biblical regulations as having made themselves unclean by doing so, and therefore was compelled to immerse their entire body. This regulation is immediately preceded by the rule against eating anything still containing blood, and according to biblical scholars this is also the context of the regulation about not eating non-sacrifices—that the regulation only treats such consumption as unclean if there is a risk of blood remaining within the carcass. In the version of this regulation in Deuteronomy, eating the bodies of such creatures is not described as making an individual ritually impure, nor requires the eater to wash their body, but instead, such consumption is expressly forbidden, although the creature is allowed to be passed on to a non-Jew, who is permitted to eat it.
Contact with a corpse
Anyone who came into contact with a cadaver or grave was so ritually impure that they had to be sprinkled with the water produced from the red heifer ritual, in order to become pure again; however, the person who carried out the red heifer ritual and who sprinkled the water was to be treated as having become ritually impure by doing so. According to Cheyne and Black, this ritual derives from the same origin as the ritual described in the Book of Deuteronomy for a group of people to atone for murder by an unknown perpetrator,Cheyne and Black, Encyclopedia Biblica according to which a heifer is killed at a stream and hands are washed over it; Peake believed that these are both ultimately cases of sympathetic magic,Peake's commentary on the Bible and similar rituals existed in GreekSophocles, Ajax, 664 and RomanVirgil, Aeneid, 2:217 mythology.Jewish Encyclopedia The Masoretic Text describes the water produced from the red heifer ritual as a sin offering;masoretic text of Numbers 19:9 some English translations discount this detail, because it differs from other sin offerings by not being killed at the altar, although biblical scholars believe that this demonstrates a failure by these translations to understand the meaning of sin offerings.
Treatment of a corpse No explicit regulations are expressed in the bible concerning the treatment of a corpse itself, although historic rabbinical sources saw an implication that the dead should be thoroughly washed per Ecclesiastes, as children are washed when born;Sefer Hasidim 560 according to Raavyah, a prominent rishon, argued that the corpse should be cleansed carefully, including the ears and fingers, with nails pared and hair combed, so that the corpse could be laid to rest in the manner that the person had visited the synagogue during life. Washing of corpses was not observed among the Jews living in Persian Babylon, for which they were criticised as dying in filth, without a candle and without a bath;Genesis Rabbah 38:5 at the time, the non-Jewish Persians were predominantly Zoroastrian, and consequently believed that dead bodies were inherently ritually unclean, and should be exposed to the elements in a Tower of Silence to avoid defiling the earth with them.
In the early periods, the body was washed in a standard mikveh, and this is frequently the form of the ritual in the present day, but the traditional washing ceremony, known as tahara, became quite detailed over time. A special building for the corpse-washing existed in the cemetery in 15th century Prague,Sefer haMaharil a practice which obtains in many Jewish communities today; a mikveh is provided at a number of ancient tombs. Female corpses are traditionally cleaned only by other females, and males only by other males.
