and Covenants 107:13-14
"The second priesthood is called the Priesthood of Aaron, because it
was conferred upon Aaron and his seed, throughout all their generations.
Why it is called the lesser priesthood is because it is an appendage to
the greater, or the Melchizedek Priesthood, and has power in administering
outward ordinances."
