Numbers 6:19-20

19And the priest shall take the boiled shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and shall put them upon the hands of the Nazirite, after he hath shaven the head of his separation; 20and the priest shall wave them for a wave-offering before Jehovah; this is holy for the priest, together with the wave-breast and heave-thigh: and after that the Nazirite may drink wine.
