15 And thou shalt ^aanoint them, as thou didst anoint their father, that they may minister unto me in the ^bpriest’s office: for their ^canointing shall surely be ^dan ^eeverlasting ^fpriesthood throughout their ^ggenerations.

  18 And the Lord confirmed a ^apriesthood also upon ^bAaron and his ^cseed, throughout all their generations, which priesthood also continueth and ^dabideth forever with the priesthood which is after the holiest order of God.

  16 No man has a legal right to this office, to hold the keys of this priesthood, except he be a ^aliteral descendant of ^bAaron.
