Numbers 6:19-20

19When the male sheep is cooked, the priest must take its shoulder. Also, he must take one cake and one thin biscuit from the basket. The cake and the biscuit must not have yeast in them. The priest must put these things into the hands of the Nazirite who has removed the hair from his head.

20The Nazirite must give those things back to the priest. The priest must lift them up to the Lord as a special gift. They are a special gift for the priest. Also, the priest can eat the front part of the sheep and its back leg. After that, the Nazirite can drink wine.”
