12 Then the Levites shall lay their hands upon the heads of the bulls, and you shall offer the one for a sin offering and the other for a burnt offering to the Lord, to make atonement for the Levites.
13 And you shall present the Levites before Aaron and his sons and offer them as a wave offering to the Lord.
14 Thus you shall separate the Levites from among the Israelites, and the Levites shall be Mine [in a very special sense].
15 And after that the Levites shall go in to do service at the Tent of Meeting, when you have cleansed them and offered them as a wave offering.
16 For they are wholly given to Me from among the Israelites; instead of all who open the womb, the firstborn of all the Israelites, I have taken the Levites for Myself.
17 For all the firstborn of the Israelites are Mine, both of man and beast; on the day that I smote every firstborn in the land of Egypt [not of Israel], I consecrated them and set them apart for Myself.
18 And I have taken the Levites instead of all the firstborn of the Israelites.
