Numbers 6:16-18 Modern English Version (MEV)
16 The priest will bring them before the Lord and will offer his sin offering and his burnt offering. 17 And he will offer the ram as a sacrifice of a peace offering to the Lord with the basket of unleavened bread. The priest will offer also his grain offering and his drink offering.
18 The Nazirite will shave his consecrated head at the door of the tent of meeting, and will take the hair from his consecrated head and put it in the fire which is under the sacrifice of the peace offerings.
