Numbers 6:16-18 New International Version - UK (NIVUK)
16 ‘“The priest is to present all these before the Lord and make the sin offering and the burnt offering. 17 He is to present the basket of unleavened bread and is to sacrifice the ram as a fellowship offering to the Lord, together with its grain offering and drink offering.
18 ‘“Then at the entrance to the tent of meeting, the Nazirite must shave off the hair that symbolises their dedication. They are to take the hair and put it in the fire that is under the sacrifice of the fellowship offering.
