Numbers 6:18-20

181The Nazirite shall then shave his dedicated head of hair at the doorway of the tent of meeting, and take the dedicated hair of his head and put it on the fire which is under the sacrifice of peace offerings. 192The priest shall take the ram’s shoulder when it has been boiled, and one unleavened cake out of the basket and one unleavened wafer, and shall put them on the 3hands of the Nazirite after he has shaved his 4dedicated hair. 20Then the priest shall wave them for a wave offering before the Lord. It is holy for the priest, together with the breast offered by waving and the thigh offered by lifting up; and 5afterward the Nazirite may drink wine.’
