Numbers 6:19-20

19And the priest shall take the shoulder of the ram, when it is boiled, and one unleavened loaf out of the basket and one unleavened wafer, and shall put them on the hands of the Nazirite, after he has shaved the hair of his consecration,

20and the priest shall wave them for a wave offering before the Lord. They are a holy portion for the priest, together with the breast that is waved and the thigh that is contributed. And after that the Nazirite may drink wine.
