Numbers 6:19-20

19The priest shall take the boiled shoulder of the ram, and one unleavened [ring-shaped] loaf out of the basket, and one unleavened flat cake and shall put them on the hands of the Nazirite after he has shaved his dedicated hair.

20Then the priest shall wave them as 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 offered by lifting up; and afterward the Nazirite may drink wine.’
