Numbers 6:19-20

And the priest shall take the sodden 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 Nazarite, after {the hair of} his separation is shaven: And the priest shall wave them {for} a wave offering before the LORD: this {is} holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine.
