KohenKohen (, kōhēn, koˈ(h)en, "priest", pl. , kōhănīm, koˈ(h)anim, "priests") is the Hebrew word for "priest", used in reference to the Aaronic priesthood, also called Aaronites or Aaronides. They are traditionally believed and halakhically required to be of direct patrilineal descent from the biblical Aaron (also Aharon), brother of Moses, and thus belong to the Tribe of Levi. During the existence of the Temple in Jerusalem (and previously the Tabernacle), kohanim performed the Temple sacrificial offerings, which were only permitted to be offered by them.
MikvehMikveh or mikvah (, () mikva'ot, mikvoth, mikvot, or (Yiddish) mikves, lit., "a collection") is a bath used for the purpose of ritual immersion in Judaism to achieve ritual purity. Most forms of ritual impurity can be purified through immersion in any natural collection of water. However, some impurities, such as a zav, require "living water", such as springs or groundwater wells. Living water has the further advantage of being able to purify even while flowing, as opposed to rainwater which must be stationary to purify.
EschatologyEschatology (ˌɛskəˈtɒlədʒi; ) concerns expectations of the end of the present age, human history, or the world itself. The end of the world or end times is predicted by several world religions (both Abrahamic and non-Abrahamic), which teach that negative world events will reach a climax. Belief that the end of the world is imminent is known as apocalypticism, and over time has been held both by members of mainstream religions and by doomsday cults.
