Numbers 6:19-20

19“ ‘After the Nazirite has shaved off the hair that symbolizes their dedication, the priest is to place in their hands a boiled shoulder of the ram, and one thick loaf and one thin loaf from the basket, both made without yeast.

20The priest shall then wave these before the Lord as a wave offering; they are holy and belong to the priest, together with the breast that was waved and the thigh that was presented. After that, the Nazirite may drink wine.
