Aaron: Priesthood of

“Next, have your brother Aaron brought to you from among the Israelites, along with his sons Nadab, Abihu, Eleazar, and Ithamar, to serve Me as priests.

And the LORD said to Moses,

So the LORD said to Aaron, “You and your sons and your father’s house must bear the iniquity involving the sanctuary. And you and your sons alone must bear the iniquity involving your priesthood.

Moses and Aaron were among His priests; Samuel was among those who called on His name. They called to the LORD and He answered.

No one takes this honor upon himself; he must be called by God, just as Aaron was.
