NET

7 But you and your sons with you are responsible for your priestly duties, for everything at the altar and within the curtain. And you must serve. I give you the priesthood as a gift for service, but the unauthorized person who approaches must be put to death.”

Darby

7 But thou and thy sons with thee shall attend to your priesthood for all that concerneth the altar, and for that which is inside the veil; and ye shall perform the service: I give you your priesthood as a service of gift, and the stranger that cometh near shall be put to death.

KJV

7 Therefore thou and thy sons with thee shall keep your priest's office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest's office [unto you] as a service of gift: and the stranger that cometh nigh shall be put to death.
