Numbers 8:13-15

New King James Version

¹³ “And you shall stand the Levites before Aaron and his sons, and then offer them like a wave offering to the Lord. ¹⁴ Thus you shall ^(A)separate the Levites from among the children of Israel, and the Levites shall be ^(B)Mine. ¹⁵ After that the Levites shall go in to service the tabernacle of meeting. So you shall cleanse them and ^(C)offer them like a wave offering.
