 Several biblical regulations specify that full immersion in water is required to regain ritual purity after ritually impure incidents have occurred.A person was required to be ritually pure in order to enter the Temple.In this context, "purity" and "impurity" are imperfect translations of the Hebrew "tahara" and "tumah", respectively, in that the negative connotation of the word impurity is not intended; rather being "impure" is indicative of being in a state in which certain things are prohibited until one has become "pure" again by immersion in a mikveh.
