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.And from the age of fifty years they shall cease waiting upon the service thereof,.... The heavy service of it:

and shall serve no more; by bearing and carrying the vessels of the sanctuary upon their shoulders, as Jarchi interprets it; this, according to the Jewish writers, was only in force while the tabernacle was in the wilderness, and was moved from place to place: but when it had a fixed habitation, and that laborious service of bearing and carrying the vessels of it ceased, years made no difference in the Levites, or disqualified them for service; for it is said (x), that the Levites were not bound by this law, but in the time of the tabernacle; but when it was at Shiloh, and at Jerusalem, where there was no bearing and carrying upon the shoulder, the Levites were not rejected on account of years, only for their voice, when they had lost that, and could not sing.
