Numbers 8:8-12

8Then they must take a bull with the proper grain offering and oil. And you must take another bull for a sin offering.

9Then you must bring the Levites in front of the Tent of Meeting. You must also bring all the Israelites there.

10You must bring the Levites in front of the Lord. Then the Israelites must put their hands on the Levites' heads.

11Aaron must give the Levites to the Lord as a special offering from the Israelites. Then they will be ready to do the Lord's work.

12Then the Levites must put their hands on the heads of the bulls. Then offer one bull for a sin offering and the other one for a burnt offering to the Lord. That will make peace with the Lord for the Levites sin.
