11 Aaron is to present the Levites before the Lord as a presentation offering from the Israelites, so that they may perform the Lord’s work.i 12 Next the Levites are to lay their hands on the heads of the bulls. Sacrifice one as a sin offering and the other as a burnt offering to the Lord, to make atonement for the Levites.j

13 “You are to have the Levites stand before Aaron and his sons, and you are to present them before the Lord as a presentation offering. 14 In this way you are to separate the Levites from the rest of the Israelites so that the Levites will belong to me.k 15 After that the Levites may come to serve at the tent of meeting, once you have ceremonially cleansed them and presented them as a presentation offering.l 16 For they have been exclusively assigned to me from the Israelites.m I have taken them for myself in place of all who come first from the womb, every Israelite firstborn.n 17 For every firstborn among the Israelites is mine, both man and animal. I consecrated them to myselfo on the day I struck down every firstborn in the land of Egypt. 18 But I have taken the Levites in place of every firstborn among the Israelites. 19 From the Israelites, I have given the Levites exclusively to Aaron and his sons to perform the work for the Israelites at the tent of meeting and to make atonement on their behalf, so that no plague will come against the Israelites when they approach the sanctuary.”p
