2 And thy brethren also, the tribe of Levi, the tribe of thy father, bring near with thee, that they may unite with thee, and minister unto thee; but thou and thy sons with thee [shall serve] before the tent of the testimony. 3 And they shall keep thy charge, and the charge of the whole tent: only they shall not come near to the vessels of the sanctuary and to the altar, that they may not die, and you as well as they. 4 And they shall unite with thee, and keep the charge of the tent of meeting, for all the service of the tent; and no stranger shall come near to you. 5 And ye shall keep the charge of the sanctuary, and the charge of the altar; that there come no wrath any more upon the children of Israel. 6 And I, behold, I have taken your brethren, the Levites, from among the children of Israel; to you are they given as a gift for Jehovah to perform the service of the tent 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.
