Numbers 6:14-18

And he shall present his offering to the Lord: one male lamb a year old without defect as a burnt offering, one ewe lamb a year old without defect as a sin offering, one ram without defect as a peace offering,

and a basket of unleavened loaves of fine flour mixed with oil and unleavened wafers spread with oil, along with their grain offering and their drink offering.

Then the priest shall present them before the Lord and offer his sin offering and his burnt offering.

He shall also offer the ram as a sacrifice of peace offerings to the Lord, together with the basket of unleavened bread; the priest shall also offer its grain offering and its drink offering.

The Nazirite shall then shave his consecrated head of hair at the entrance of the tent of meeting, and take the consecrated hair of his head and put it on the fire which is under the sacrifice of peace offerings.
