5 Then the Lord spoke to Moses, saying: 6 "Take the Levites from among the children of Israel and cleanse them ceremonially. 7 Thus you shall do to them to cleanse them: Sprinkle water of purification on them, and let them shave all their body, and let them wash their clothes, and so make themselves clean. 8 Then let them take a young bull with its grain offering of fine flour mixed with oil, and you shall take another young bull as a sin offering. 9 And you shall bring the Levites before the tabernacle of meeting, and you shall gather together the whole congregation of the children of Israel. 10 So you shall bring the Levites before the Lord, and the children of Israel shall lay their hands on the Levites; 11 and Aaron shall offer the Levites before the Lord, like a wave offering from the children of Israel, that they may perform the work of the Lord. 12 Then the Levites shall lay their hands on the heads of the young bulls, and you shall offer one as a sin offering and the other as a burnt offering to the Lord, to make atonement for the Levites. 13 And you shall stand the Levites before Aaron and his sons, and then offer them like a wave offering to the Lord. 14 Thus you shall separate the Levites from among the children of Israel, and the Levites shall be Mine. 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. 16 For they are wholly given to Me from among the children of Israel; I have taken them for Myself instead of all who open the womb, the firstborn of all the children of Israel. 17 For all the firstborn among the children of Israel are Mine, both man and beast; on the day that I struck all the firstborn in the land of Egypt I sanctified them to Myself. 18 I have taken the Levites instead of all the firstborn of the children of Israel. 19 And I have given the Levites as a gift to Aaron and his sons from among the children of Israel, to do the work for the children of Israel in the tabernacle of meeting, and to make atonement for the children of Israel, that there be no plague among the children of Israel when the children of Israel come near the sanctuary." 20 Thus Moses and Aaron and all the congregation of the children of Israel did to the Levites; according to all that the Lord commanded Moses concerning the Levites, so the children of Israel did to them. 21 And the Levites purified themselves and washed their clothes; then Aaron presented them, like a wave offering before the Lord, and Aaron made atonement for them to cleanse them. 22 After that the Levites went in to do their work in the tabernacle of meeting before Aaron and his sons; as the Lord commanded Moses concerning the Levites, so they did to them.

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.
