8:7 And thus shalt thou do unto them, to cleanse them: Sprinkle {c} water of purifying upon them, and let them shave all their flesh, and let them wash their clothes, and [so] make themselves clean.
(c) In Hebrew it is called the water of sin, because it is made to purge sin, as in Nu 19:9.
8:7 Of purifying - Heb. of sin, that is, for the expiation of sin. This water was mixed with the ashes of a red heifer, Num 19:9, which therefore may seem to have been prescribed before, though it be mentioned after; such kind of transplacings of passages being frequent in scripture. Shave all their flesh - This external rite signified the cutting off their inordinate desire of earthly things and that singular purity of heart and life which is required in the ministers of God.
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.
