Numbers 6:19-20

19The kohen is to take the boiled shoulder of the ram and one matzah cake and one matzah wafer from the basket, and he is to place them into the hands of the Nazirite after he has shaved the hair of his dedication.

20The kohen will wave them before Adonai as a wave offering. They are holy, and belong to the kohen along with the breast that was waved and the thigh that was presented. Afterward, the Nazirite may drink wine.
