Numbers 8:8-12

8Next, they must take a young bull and the grain offering of flour mixed with olive oil that is offered with it. You must take a second young bull as an offering for sin.

9Bring the Levites to the front of the tent of meeting, and assemble the whole community of Israel.

10Then bring the Levites into the Lord’s presence, and the Israelites will place their hands on them.

11Aaron will present the Levites to the Lord as an offering from the Israelites. Then they will be ready to do the Lord’s work.

12“The Levites will place their hands on the heads of the young bulls. Sacrifice one of them as an offering for sin and the other one as a burnt offering to the Lord. These sacrifices will make peace with the Lord for the Levites.
