(15) And after that shall the Levites go in . . . —i.e., into the court of the Tabernacle to keep watch there, and to assist the priests at the altar of burnt-offering, and to take down and set up the Tabernacle as occasion might require.

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.Offer ... offering - Compare the margin Aaron pointed to the Levites, and then waved his hands, indicating (compare Leviticus 7:30 note) that the offering was dedicated to God, and, again, by grant from Him, withdrawn for the use of the priests.15. after that, shall the Levites go in to do the service of the tabernacle of the congregation—into the court, to assist the priests; and at removal into the tabernacle—that is, into the door of it—to receive the covered furniture. The Levites go in, to wit, into the court, where they were to wait upon the priests at the altar of burnt-offering; and, at present, into the tabernacle, to take it down and set it up.

And after that shall the Levites go in,.... Not into the sanctuary, where only the priests entered, much less into the most holy place, where only the high priest went, and that but once a year, in neither of which places the Levites had anything to do, but into the court of the tabernacle:

to do the service of the tabernacle of the congregation: to watch there, and to assist the priests at the altar of burnt offering, to take down the tabernacle and bear the vessels of it, and set it up, as occasion required:

and thou shalt cleanse them, and offer them for an offering; cleanse them by sprinkling the water of purifying on them, and offer them by waving them as before; and indeed this is no new thing which is here observed, but what was already done, and therefore should be rendered, "when thou shalt have cleansed them", or "after thou hast cleansed them", &c. and so the particle "vau" is sometimes used (t).
