15 "After you have purified the Levites and presented them as a wave offering, they are to come to do their work at the tent of meeting.
15 And after that shall the Levites go in to do the service of the tabernacle of the congregation: and thou shalt cleanse them, and offer them for an offering.
15 And after that the Levites shall go in to serve at the tent of meeting, when you have cleansed them and offered them as a wave offering.
15 "After you have purified the Levites and presented them as a Wave-Offering to God, they can go to work in the Tent of Meeting.
15 After that the Levites shall go in to service the tabernacle of meeting. So you shall cleanse them and offer them, like a wave offering.
15 After this, they may go into the Tabernacle to do their work, because you have purified them and presented them as a special offering.
Matthew Henry's Commentary on Numbers 8:15
Commentary on Numbers 8:5-26
(Read Numbers 8:5-26)
Here we have directions for the solemn ordination of the Levites. All Israel must know that they took not this honour to themselves, but were called of God to it; nor was it enough that they were distinguished from others. All who are employed for God, must be dedicated to him, according to the employment. Christians must be baptized, ministers must be ordained; we must first give ourselves unto the Lord, and then our services. The Levites must be cleansed. They must be clean that bear the vessels of the Lord. Moses must sprinkle the water of purifying upon them. This signifies the application of the blood of Christ to our souls by faith, that we may be fit to serve the living God. God declares his acceptance of them. All who expect to share in the privileges of the tabernacle, must resolve to do the service of the tabernacle. As, on the one hand, none of God's creatures are his necessary servants, he needs not the service of any of them; so none are merely honorary servants, to do nothing. All whom God owns, he employs; angels themselves have their services.
