2 "Bring your relatives of the tribe of Levi-your ancestral tribe-to assist you and your sons as you perform the sacred duties in front of the Tabernacle of the Covenant. 3 But as the Levites go about all their assigned duties at the Tabernacle, they must be careful not to go near any of the sacred objects or the altar. If they do, both you and they will die. 4 The Levites must join you in fulfilling their responsibilities for the care and maintenance of the Tabernacle, but no unauthorized person may assist you. 5 "You yourselves must perform the sacred duties inside the sanctuary and at the altar. If you follow these instructions, the Lord 's anger will never again blaze against the people of Israel. 6 I myself have chosen your fellow Levites from among the Israelites to be your special assistants. They are a gift to you, dedicated to the Lord for service in the Tabernacle.

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.
