2 Also bring with you your brethren of the tribe of Levi, the tribe of your father, that they may be joined with you and serve you while you and your sons are with you before the tabernacle of witness. 3 They shall attend to your needs and all the needs of the tabernacle; but they shall not come near the articles of the sanctuary and the altar, lest they die--they and you also. 4 They shall be joined with you and attend to the needs of the tabernacle of meeting, for all the work of the tabernacle; but an outsider shall not come near you. 5 And you shall attend to the duties of the sanctuary and the duties of the altar, that there may be no more wrath on the children of Israel. 6 Behold, I Myself have taken your brethren the Levites from among the children of Israel; they are a gift to you, given by the Lord, to do the work of the tabernacle of meeting.
Matthew Henry's Commentary on Numbers 18:2-6
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.
