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.

And thy brethren also. He here assigns their duties to the Levites, that they also may minister, but, as it were, under the hand of the priests, viz., that they may be ruled by their commands. Thus the authority was in the hands of the priests, but the Levites afforded them their assistance. On this ground they are prohibited from approaching the altar, or entering the greater sanctuary; in fact, a lower degree is assigned to them, half-way between the priests and the people. Hence did all learn how reverently God's majesty must be served; for although He had adopted the whole people, yet so far was it from being lawful that any of the multitude should penetrate to the altar, that the Law even kept back the Levites from thence, although they were God's peculiar ministers. Moreover, in this figure, we perceive how necessary is a Mediator for us to conciliate God's favor towards us; for, if it was not allowable for the holy and chosen seed of Abraham to approach the typical sanctuary, how should we, who were aliens, now penetrate to heaven, unless a way of access were opened to us through Christ? Finally, when He forbids strangers from meddling with holy things, He does not mean only foreigners, but all the people, except the tribe of Levi; for here a distinction is drawn, not between the Church and heathen nations, but between the ministers of the sanctuary and the rest of the people.
Thy brethren also of the tribe of Levi - may be joined unto thee - There is a fine paronomasia, or play upon words, in the original. לוי Levi comes from the root לוה lavah, to join to, couple, associate: hence Moses says, the Levites, ילוו yillavu, shall be joined, or associated with the priests; they shall conjointly perform the whole of the sacred office, but the priests shall be principal, the Levites only their associates or assistants.
And to thy brethren also of the tribe of Levi, the tribe of thy father,.... For his father Amram was of that tribe, and so the Levites were his brethren, as he is directed to consider them; which might serve to conciliate their minds, and make them easy with respect to his enjoyment of the priesthood:
bring them with thee; into the court of the tabernacle, for further they might not go:
that they maybe joined unto thee: as their name of Levites signifies, persons joined and united to others, as they were to the priests: see reason of their patriarch's name Levi in Genesis 29:34,
and minister unto thee: be assisting to the priests in killing the sacrifices, receiving the blood, and flaying the beasts, and in other things about the sanctuary, Numbers 3:6,
but thou, and thy sons with thee, shall minister before the tabernacle of witness; which was the most holy place, where were the ark of the testimony or witness, and the tables of the covenant; and they might be said to minister before that, when they ministered in the holy place, which was before it, when they burned incense upon the altar of incense, ordered the shewbread, and trimmed the lamps of the candlestick, which none but the priests the sons of Aaron might do.
thy brethren also of the tribe of Levi--The departments of the sacred office, to be filled respectively by the priests and Levites, are here assigned to each. To the priests was committed the charge of the sanctuary and the altar, while the Levites were to take care of everything else about the tabernacle. The Levites were to attend the priests as servants--bestowed on them as "gifts" to aid in the service of the tabernacle--while the high and dignified office of the priesthood was a "service of gift." "A stranger," that is, one, neither a priest nor a Levite, who should intrude into any departments of the sacred office, should incur the penalty of death.
Unto thee - About sacrifices and offerings and other things, according to the rules I have prescribed them. The Levites are said to minister to Aaron here, to the church, Numbers 16:9, and to God, Deuteronomy 10:8. They shall not contend with thee for superiority, as they have done, but shall be subordinate to thee. Thy sons with thee - Or, both to thee, and to thy sons with thee: Which translation may seem to be favoured by the following words, before the tabernacle, which was the proper place where the Levites ministered. Besides, both the foregoing words, and the two following verses, entirely speak of the ministry of the Levites, and the ministry of the priests is distinctly spoken of, Numbers 18:5.
