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.
