Numbers 8:10-12

New American Standard Bible

¹⁰ and present the Levites before the Lord; and the sons of Israel ^(A)shall lay their hands on the Levites. ¹¹ Aaron then shall ^[a]present the Levites before the Lord as a ^(B)wave offering from the sons of Israel, so that they may ^[b]qualify to perform the service of the Lord. ¹² Now ^(C)the Levites shall lay their hands on the heads of the bulls; then you are to offer the one as a sin offering and the other as a burnt offering to the Lord, to make atonement for the Levites.
