21 And the Levites were made clean from sin, and their clothing was washed, and Aaron gave them for a wave offering before the Lord; and Aaron took away their sin and made them clean.
And this is how you are to make them clean: let the holy water which takes away sin be put on them, and let the hair all over their bodies be cut off with a sharp blade, and let their clothing be washed and their bodies made clean.

Then the Levites are to be put before Aaron and his sons, to be offered as a wave offering to the Lord.
