Ritual washing in Judaism in the context of "Maimonides"

A mikveh or Mikvah (Hebrew: מִקְוֶה / מקווה, Modern: mīqve, Tiberian: mīqwe, pl. mikva'ot, mikvot, or (Ashkenazic) mikves, lit. 'a collection') is a bath used for ritual immersion in Judaism to achieve ritual purity.

In Orthodox Judaism, these regulations are steadfastly adhered to; consequently, the mikveh is central to an Orthodox Jewish community. Conservative Judaism also formally holds to the regulations. The existence of a mikveh is considered so important that, according to halacha, a Jewish community is required to construct a kosher mikveh even before building a synagogue, and must go to the extreme of selling Torah scrolls, or even a synagogue if necessary, to provide funding for its construction.

In Jewish religious law, there is a category of specific Jewish purity laws, defining what is ritually impure or pure: ṭum'ah (Hebrew: טומאה, pronounced [tumˈʔa]) and ṭaharah (Hebrew: טהרה, pronounced [tahaˈra]) are the state of being ritually "impure" and "pure", respectively. The Hebrew noun ṭum'ah, meaning "impurity", describes a state of ritual impurity. A person or object which contracts ṭum'ah is said to be ṭamé (טמא‎ Hebrew adjective, "ritually impure"), and thereby unsuited for certain holy activities and uses (kedushah, קְדֻשָּׁה‎‎ in Hebrew) until undergoing predefined purification actions that usually include the elapse of a specified time-period.

The contrasting Hebrew noun ṭaharah (טָהֳרָה‎) describes a state of ritual purity that qualifies the ṭahor (טָהוֹר‎; ritually pure person or object) to be used for kedushah. The most common method of achieving ṭaharah is by the person or object being immersed in a mikveh (ritual bath). This concept is connected with ritual washing in Judaism, and both ritually impure and ritually pure states have parallels in ritual purification in other world religions.
