Numbers 6:12-16

and shall live his days of consecration as a Nazirite for the Lord, and shall bring a male lamb a year old as a guilt offering; but the preceding days will not count, because his consecration was defiled.

‘Now this is the law of the Nazirite when the days of his consecration are fulfilled: he shall bring his offering to the entrance of the tent of meeting.

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.
