Numbers 6:19-20

19‘And the priest shall take the boiled shoulder of the ram, one unleavened cake from the basket, and one unleavened wafer, and put them upon the hands of the Nazirite after he has shaved his consecrated hair,

20and the priest shall wave them as a wave offering before the Lord; they are holy for the priest, together with the breast of the wave offering and the thigh of the heave offering. After that the Nazirite may drink wine.’
