SEV Biblia, Chapter 18:7
Mas tú y tus hijos contigo guardaréis vuestro sacerdocio en todo negocio del altar, y del velo adentro, y ministraréis; porque yo os he dado en don el servicio de vuestro sacerdocio; y el extraño que se acercare, morirá.
John Gill's Bible Commentary
Ver. 7. Therefore thou and thy sons with thee shall keep your priest’s office , etc.] 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.
Matthew Henry Commentary
Verses 1-7 - The people complained of their difficulty and peril in drawing near to God. God here gives them to understand, that the priests should com near for them. Aaron would see reason not to be proud of his preferment, when he considered the great care and charge upon him. Be not high-minded, but fear. The greater the trust of work and power tha is committed to us, the greater danger there is of betraying tha trust. This is a good reason why we should neither envy others honours, nor desire high places.
