Matthew Henry
Here,
wait on their priests’ office: the apostle uses this phrase (Rom 12:7),
Let us wait on our ministry. The office of the ministry requires a constant attendance and great diligence; so frequent are the returns of its work, and yet so transient its favourable opportunities, that it must be waited on. Here is repeated what was said before (Num 1:51):
The stranger that cometh nigh shall be put to death, which forbids the invading of the priest’s office by any other person whatsoever; none must come nigh to minister but Aaron and his sons only, all others are strangers. It also lays a charge on the priests, as door-keepers in God’s house, to take care that none should come near who were forbidden by the law; they must keep off all intruders, whose approach would be to the profanation of the holy things, telling them that if they came near it was at their peril, they would
die by the hand of God, as Uzza did. The Jews say that afterwards there was hung over the door of the temple a golden sword (perhaps alluding to that flaming sword at the entrance of the garden of Eden), on which was engraven,
The stranger that cometh nigh shall be put to death.
offered strange fire, and died for so doing,
before the Lord. This is mentioned here in the preamble to the law concerning the priesthood, for a warning to all succeeding priests; let them know, by this example, that God is a jealous God, and will not be mocked; the holy anointing oil was an honour to the obedient, but not a shelter to the disobedient. It is here said,
They had no children, Providence so ordering it, for their greater punishment, that none of their descendants should remain to be priests, and so bear up their name who had profaned God’s name.
in the sight of Aaron. It intimates,
see their children walk in the truth, 3John 1:4.
Give the Levites to Aaron, Num 3:9. Aaron was to have a greater propriety in, and power over, the tribe of Levi than any other of the prices had in and over their respective tribes. There was a great deal of work belonging to the priests’ office, and there were now only three pairs of hands to do it all, Aaron’s and his two sons’; for it does not appear that they had either of them any children at this time, at least not any that were of age to minister, therefore God appoints the Levites to attend upon them. Note, Those whom God finds work for his will find help for. Here is,
minister to the priestsin their ministration to the Lord (Num 3:6), and to
keep Aaron’s charge(Num 3:7), as the deacons to the bishops in the evangelical constitution, serving at tables, while the bishops waited on their ministry. The Levites killed the sacrifices, and then the priests needed only to sprinkle the blood and burn the fat: the Levites prepared the incense, the priests burnt it. They were to keep, not only Aaron’s charge, but the
charge of the whole congregation. Note, It is a great trust that is reposed in ministers, not only for the glory of Christ, but for the good of his church; so that they must not only keep the charge of the great high priest, but must also be faithful to the souls of men, in trust for whom a dispensation is committed to them.
All the first-born are mine. That was sufficient to make them his, though he had given no reason for it, for he is the sole fountain and Lord of all beings and powers; but because all obedience must flow from love, and acts of duty must be acts of gratitude, before they were challenged into peculiar services they were crowned with peculiar favours. Note, When he that made us saves us we are thereby laid under further obligations to serve him and live to him. God’s right to us by redemption corroborates the right he has to us by creation. Now because the first-born of a family are generally the favourites, and some would think it a disparagement to have their eldest sons servants to the priests, and attending before the door of the tabernacle, God took the tribe of Levi entire for his own, in lieu of the first-born, Num 3:12. Note, God’s institutions put no hardships upon men in any of their just interests or reasonable affections. It was presumed that the Israelites would rather part with the Levites than with the first-born, and therefore God graciously ordered the exchange; yet for us he
spared not his own Son.
