 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.The laws of "ṭumah" and "ṭaharah" were generally followed by the Israelites, particularly during the First and Second Temple Period, and to a limited extent are a part of applicable "halakha" in modern times.The Hebrew noun "ṭum'ah" () derives from the verb "ṭamé" (), in the qal form of the verb "to become impure"; in the niphal to "defile oneself"; and in the transitive Piel to defile something or pronounce something impure.
