Kohen 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, brother of Moses, and thus belong to the Tribe of Levi.

According to the Hebrew Bible, the tabernacle, also known as the Tent of the Congregation, was the portable earthly dwelling used by the Israelites from the Exodus until the conquest of Canaan. Moses was instructed at Mount Sinai to construct and transport the tabernacle with the Israelites on their journey through the wilderness and their subsequent conquest of the Promised Land. After 440 years, Solomon's Temple in Jerusalem superseded it as the dwelling-place of God.
