Ablution in Judaism

In Judaism, ritual washing, 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 (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 customs 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.

The Hebrew Bible includes various regulations about bathing:

A subsequent seven clean days are then required, culminating in a ritual and temple offering before the zav is clean of his malady:

And also references to hand-washing:

Philo of Alexandria refers to ritual washing in the context of the Temple and Leviticus, but also speaks of spiritual "washing." At Qumran basins which served as baths have been identified, and among the Dead Sea scrolls texts on maintaining ritual purity reflect the requirements of Leviticus.

Both traditional religious and secular scholars agree that ritual washing in Judaism was derived by the Rabbis of the Talmud from a more extensive set of ritual washing and purity practices in use in the days of the Temple in Jerusalem, based on various verses in the Hebrew Bible 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.
