You are to have the Levites stand before Aaron ¹  and his sons, and then offer them as a wave offering to the Lord.

and Aaron is to offer ¹  the Levites before the Lord as a wave offering from the Israelites, that they may do the work ²  of the Lord.

“After this, the Levites will go in ¹  to do the work ²  of the tent of meeting. So you must cleanse them ³  and offer them like a wave offering. ⁴ 

The Levites purified themselves ¹  and washed their clothing; then Aaron presented them like a wave offering before the Lord, and Aaron made atonement for them to purify them.

then the priest must wave them as a wave offering ¹  before the Lord; it is a holy portion for the priest, together with the breast of the wave offering and the thigh of the raised offering. ²  After this the Nazirite may drink ³  wine.’
