4  And no man taketh this honour unto himself, but he that is called of God, as was Aaron.

  18  We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.

  7  And the sons of ^aAaron the priest shall put fire upon the altar, and lay the wood in order upon the fire:

  15  Wherefore they shall be high priests who are worthy, and they shall be appointed by the First Presidency of the Melchizedek Priesthood, except they be literal descendants of ^cAaron.

  30  And again, the offices of teacher and deacon are necessary appendages belonging to the lesser priesthood, which priesthood was confirmed upon ^bAaron and his sons.
