The Lord said to Aaron, “You, your sons, and your ancestral house will be responsible for sin against the sanctuary. You and your sons will be responsible for sin involving your priesthood.
But you and your sons will carry out your priestly responsibilities for everything concerning the altar and for what is inside the veil, and you will do that work. I am giving you the work of the priesthood as a gift, but an unauthorized person who comes near the sanctuary will be put to death.”
You are to appoint Aaron and his sons to carry out their priestly responsibilities, but any unauthorized person who comes near the sanctuary must be put to death.”
