Numbers 8:11-13

New American Standard Bible

¹¹ Aaron then shall ^[a]present the Levites before the Lord as a ^(A)wave offering from the sons of Israel, so that they may ^[b]qualify to perform the service of the Lord. ¹² Now ^(B)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. ¹³ And you shall have the Levites stand before Aaron and his sons so as to present them as a wave offering to the Lord.
