2 Your brothers also, the tribe of Levi, the tribe of your father, bring near with you, that they may be joined to you, and minister to you: but you and your sons with you shall be before the tent of the testimony.

Matthew Henry's Commentary on Numbers 18:2

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.
