7 You and your sons with you shall keep your priesthood for everything of the altar, and for that within the veil; and you shall serve: I give you the priesthood as a service of gift: and the stranger who comes near shall be put to death."

Therefore thou and thy sons with thee shall keep your priest's office,.... Observe all the duties of it, and keep out others from intruding into it:
for everything of the altar: both of incense and of burnt offering with respect to burning incense on the one, and offering sacrifices on the other; both were to be done by priests, and by no other:
and within the vail; in the most holy place, where the high priest entered but once a year, and he only with incense, and the blood of sacrifices, see Hebrews 9:7,
and ye shall serve; do all the business that is to be done at either altar, whether in the court, or in the holy place, and whatsoever is to be done in the most holy place within the vail:
I have given your priest's office unto you as a service of gift; it was not what they had taken to themselves of their own will, or had thrust themselves into, but what the Lord had called them to, and had freely invested them with, see Hebrews 5:4,
and the stranger that cometh nigh shall be put to death; any common person, as the Targums of Onkelos and Jonathan; any Israelite, one that is a stranger from the priests, though a Levite, as Aben Ezra; such an one might not come either to the altar of burnt offering to offer any sacrifice upon it, or the altar of incense, to burn incense on that, or trim the lamps, or put the shewbread in order, or to do anything peculiar to the priest's office.
The altar - Of burnt - offering. Within the veil - This phrase here comprehends both the holy and the most holy place. As a gift which I have freely conferred upon you, and upon you alone; and therefore let no man henceforth dare either to charge you with arrogance in appropriating this to yourselves, or to invade your office.
