181 And the Lord said to Aaron, You and your sons and your father's family are to be responsible for all wrongdoing in relation to the holy place: and you and your sons are to be responsible for the errors which come about in your work as priests. 2 Let your brothers, the family of Levi, come near with you, so that they may be joined with you and be your servants: but you and your sons with you are to go in before the ark of witness. 3 They are to do your orders and be responsible for the work of the Tent; but they may not come near the vessels of the holy place or the altar, so that death may not overtake them or you. 4 They are to be joined with you in the care of the Tent of meeting, doing whatever is needed for the Tent: and no one of any other family may come near you. 5 You are to be responsible for the holy place and the altar, so that wrath may never again come on the children of Israel. 6 Now, see, I have taken your brothers the Levites from among the children of Israel: they are given to you and to the Lord, to do the work of the Tent of meeting. 7 And you and your sons with you are to be responsible as priests for the altar and everything on it, and everything inside the veil; you are to do the work of priests; I have given you your position as priests; and any other man who comes near will be put to death.

Commentary on Numbers 18:1-7
(Read Numbers 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.
