And ye shall keep the charge of the sanctuary,.... That is, the priests, Aaron and his sons; the high priest was to keep the charge of the most holy place particularly, and do what was to be done in that on the day of atonement; and the common priests to keep the charge of the holy place, and do everything relating to the altar of incense, the shewbread table, and candlestick:

and the charge of the altar; of burnt offering, which stood in the court of the tabernacle:

that there be no wrath any more upon the children of Israel: as had been upon Korah and his company, Numbers 16:32, and as afterwards came on Uzziah, 2 Chronicles 26:19.

The charge of the sanctuary (i.e., the dwelling) and the altar (of burnt-offering) devolved upon Aaron and his sons, that the wrath of God might not come again upon the children of Israel (see Numbers 8:19), - namely, through such illegal acts as Nadab and Abihu (Leviticus 10:2), and the company of Korah (Numbers 16:35), had committed. To this end God had handed over the Levites to them as a gift, to be their assistants (see at Numbers 3:9 and Numbers 8:16, Numbers 8:19). But Aaron and his sons were to attend to the priesthood "with regard to everything of the altar and within the vail" (i.e., of the most holy place, see Leviticus 16:12). The allusion is to all the priestly duties from the altar of burnt-offering to the most holy place, including the holy place which lay between. This office, which brought them into the closest fellowship with the Lord, was a favour accorded to them by the grace of God. This is expressed in the words, "as a service of gift (a service with which I present you) I give you the priesthood." The last words in Numbers 18:7 are the same as in Numbers 1:51; and "stranger" (zar), as in Leviticus 22:10.

And ye shall keep the charge of the sanctuary, and the charge of the altar: that there be no wrath any more upon the children of Israel.

18:5 The sanctuary - Of the holy, and of the most holy place.

18:1-7 The people complained of their difficulty and peril in drawing near to God. God here gives them to understand, that the priests should come 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 that is committed to us, the greater danger there is of betraying that trust. This is a good reason why we should neither envy others' honours, nor desire high places.
