Ablution in Judaism
Encyclopedia
Ritual washing in Judaism, or ablution, takes two main forms. A tevilah (טְבִילָה) is a full body immersion in a mikveh, and a netilat yadayim which is the washing of the hands with a cup.

Hebrew Bible

The Hebrew Bible includes various regulations about bathing:
And whoever he that hath issue (a zav, ejaculant with an unusual discharge) touches without having rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the evening


And also references to hand-washing:
I will wash my hands in innocence; so will I compass Thine altar, O LORD

 and received traditions. There is disagreement, however, about the origins and meanings of these practices. This article first describes these practices as they exist in contemporary traditional Judaism, then discusses various alternative perspectives on their nature, origins, and meaning.

Traditional Judaism requires certain types of ritual washing. Some of these types do not require a special ritual body of water (and can be done with tap water):
  1. Netilat Yadayim Shacharit ("Raising [after ritually washing] the hands of the morning"), when getting up in the morning after a full night's sleep, or even after a lengthy nap, there is the custom to wash one's hands ritually by pouring a large cup of water over one's hands, alternating three times. In the custom of some communities, it is also done without a blessing after engaging in sexual intercourse
    Sexual intercourse
    Sexual intercourse, also known as copulation or coitus, commonly refers to the act in which a male's penis enters a female's vagina for the purposes of sexual pleasure or reproduction. The entities may be of opposite sexes, or they may be hermaphroditic, as is the case with snails...

At meals

The Babylonian Talmud discusses two types of washing at meals: washing before a meal is described as first waters (the Hebrew term is mayim rishonim), and after a meal is known as last waters (the Hebrew term is mayim aharonim). The first term has generally fallen from contemporary usage; the second term has stuck. The modern term for the former is Ntillat yadayim, washing of hands. Washing before meals is normative in Orthodox Judaism

, and risks divine punishment in the form of sudden destruction or poverty. The discussion of mayim acharonim, washing after meals, contains a suggestion that washing after meals, as a health measure, is the more important of the two washings, on grounds that the salt used as a preservative in food could cause blindness if the eyes were rubbed without washing.

Although mayim acharonim was once not widely practiced (for example, until recently it did not appear in many Orthodox Passover Haggadahs) it has undergone something of a revival and has become more widely observed in recent years, particularly for special meals such as the Shabbat

The hands are also washed:

  • after cutting one's hair or nails
  • after participating in a funeral procession, upon leaving a cemetery, or coming within four cubits of a corpse
  • after touching a normally covered part of your body (private parts, back , arm pits, etc.)
  • after touching inside of nose and ear
  • after touching the scalp, but not if you just touched the hair
  • prior to scribal work (optional)

Full-body immersion

There are several occasions on which biblical or rabbinical regulations require immersion of the whole body, referred to as tevilah. Depending on the circumstances, such ritual bathing might require immersion in "living water" - either by using a natural stream or by using a mikveh (a specially constructed ritual bath, connected directly to a natural source of water, such as a spring).

This article discusses the requirements of immersion in Rabbinic Judaism and its descendents. Some other branches of Judaism, such as Falasha Judaism, have substantially different practices including the requirement of an actual spring or stream.

Conversion to Judaism

Traditional Judaism requires converts into Judaism to immerse themselves fully in water in a mikveh or body of "living water."

 and remained in a state of ritual impurity for 7 days prior to 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.

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

, 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.

Between death and the traditional ceremony, the body is placed on the ground, and covered with a sheet, and at the start of the traditional ceremony, the body is lifted from the ground onto a special board or slab (a tahara board), so that it lies facing the door, with a white sheet underneath. The clothes are then removed from the corpse (if they were not been removed when the corpse was placed on the ground), and at this point is recited by the enactors of the ritual, as it refers to the removal of filthy clothes. Following this, the body is thoroughly rubbed with lukewarm

Finally, nine measures of cold water are poured over the body while it is upright, which is the core element of the ceremony, and it is then dried (according to some customs), and enshroud

. All three ruled the traditional requirements of ritual washing remained in effect for Conservative Jews (with some leniencies and liberalization of interpretation), but disagreed on the reasoning for continuing this practices as well as on the validity of specific leniencies. Two of the opinions reflect reasoning similar to the respective Orthodox views (Biblical requirements or rabbinic ordinances enacted in remembrance of the Temple.) A third opinion expressed the view that Conservative Judaism should disconnect ritual purity practices from the Temple in Jerusalem or its memory, and offered a new apprach based on what it called the concept of holiness rather than the concept of purity. Thus, Conservative ideology, under its philosophy of pluralism, supports a range of views on this subject, from views similar to the Orthodox view to views expressing a need for a contemporary reorientation. Most Conservative Jews do not observe the laws of niddah.

Secular historical and scholarly commentary

According to the editors of the 1906 Jewish Encyclopedia
Jewish Encyclopedia
The Jewish Encyclopedia is an encyclopedia originally published in New York between 1901 and 1906 by Funk and Wagnalls. It contained over 15,000 articles in 12 volumes on the history and then-current state of Judaism and the Jews as of 1901...

, the phrase netilat yadaim referring to washing of the hands, literally "lifting of the hands", is derived either from Psalm 134:2, or from the Greek word natla (αντλίον), in reference to the jar of water used. The Jewish Encyclopedia states that many historic Jewish writers, and particularly the Pharisees, took it to mean that water had to be poured out onto uplifted hands, and that they could not be considered clean until water had reached the wrist. This is commented on by the Synoptic Gospels

, which state that these groups didn't eat until they had washed their hands to the wrist, but the Gospels castigates them for this, arguing that it was only followed as an ostentatious tradition, ignoring religious obligations, and that washing the hands was worthless without inward religious obligations also being adhered to, and insignificant if the inward obligations, such as giving all of one's possessions to the poor, were followed.

According to the Jewish Encyclopedia, the historic requirement for priests to first wash their hands, together with the classical rabbinical belief that non-priest were also required to wash their hands before taking part in a holy act, such as prayer, was adhered to very strongly, to the extent that Christianity adopted the practice, and provided worshippers with fountains and basins of water in Churches, in a similar manner to the "Molten Sea
