And you shall appoint Aaron and his sons, and they shall guard their priesthood. But if any outsider comes near, he shall be put to death.
Numbers 3:10
Only a physical, male descendant of Aaron can offer sacrifices in the earthly Tabernacle or Temple. No women and no kings, prophets, or Levites who are not sons of Aaron. Not even Messiah may act in the place of a Levitical priest. (The Tabernacle in Heaven is another matter.)
