And the Nazarite shall shave the head of his separation— The shaving off the hair, mentioned in the 9th verse, differed totally from this. The former was in consequence of legal uncleanness; this was to be done as a public thankful testimony that the Nazarite had ended his vow, and had no further obligation to let his hair grow. See Acts 18:18; Acts 21:23-24. The Nazarite, beside this, (see Numbers 6:14.) was to offer three principal sacrifices: a burnt-offering, in testimony of his entire and unreserved devotion; a sin-offering, to implore pardon for his defects; and an eucharistical or peace-offering, in gratitude to God, the giver of all good. Houbigant renders the last clause of this verse, shall put it upon the fire placed under the peace-offering. See Calmet.
