Numbers 6:19

17He shall offer the ram for a sacrifice of peace offerings to the LORD, with the basket of unleavened bread. The priest shall offer also its meal offering and its drink offering.

18The Nazirite shall shave the head of his separation at the door of the Tent of Meeting, take the hair of the head of his separation, and put it on the fire which is under the sacrifice of peace offerings.

19The priest shall take the boiled shoulder of the ram, one unleavened cake out of the basket, and one unleavened wafer, and shall put them on the hands of the Nazirite after he has shaved the head of his separation;

20and the priest shall wave them for a wave offering before the LORD. They are holy for the priest, together with the breast that is waved and the thigh that is offered. After that the Nazirite may drink wine.

21“‘This is the law of the Nazirite who vows and of his offering to the LORD for his separation, in addition to that which he is able to afford. According to his vow which he vows, so he must do after the law of his separation.’”
