(Philippians 1:29; Colossians 1:18) These are also designated members of the royal priesthood.

(1 Peter 2:9,10) During their earthly career they are counted as members of the sacrificing priesthood, of which Aaron was a type.

Aaron and his sons were required to serve before the Lord in the ceremonies in connection with the tabernacle in the wilderness.

Two of Aaron's sons were stricken dead because they offered strange fire before the Lord.

Aaron and his two remaining sons were forbidden by the Lord to mourn the death of their kinsmen.
