Numbers 6:19-20

19After the Nazirite’s head has been shaved, the priest will take for each of them the boiled shoulder of the ram, and he will take from the basket a cake and a wafer made without yeast. He will put them all into the Nazirite’s hands.

20Then the priest will lift them up as a special offering before the Lord. These are holy portions for the priest, along with the breast of the special offering and the thigh of the sacred offering that are lifted up before the Lord. After this ceremony the Nazirites may again drink wine.
