Barnes' Notes
The law of the Nazarite is appropriately added to other enactments which concern the sanctity of the holy nation. That sanctity found its highest expression in the Nazarite vow, which was the voluntary adoption for a time of obligations to high and strict modes of self-dedication resembling, and indeed in some particulars exceeding, those under which the priests were placed. The present enactments do not institute a new kind of observance, but only regulate one already familiar to the Israelites Numbers 6:2.
Numbers 6:2
A Nazarite - Strictly, Nazirite. This term signifies "separated" i. e., as the words following show, "unto God." It became a technical term at an early date; compare Judges 13:5, Judges 13:7; Judges 16:17.
Numbers 6:3
Liquor of grapes - i. e. a drink made of grape-skins macerated in water.
Numbers 6:4
From the kernels even to the husk - A sour drink was made from the stones of unripe grapes; and cakes were also made of the husks Hosea 3:1. This interdict figures that separation from the general society of men to which the Nazarite for the time was consecrated.
Numbers 6:5
Among the Jews the abundance of the hair was considered to betoken physical strength and perfection (compare II Samuel 14:25-26), and baldness was regarded as a grave blemish (compare Leviticus 21:20 note, Leviticus 13:40 ff; II Kings 2:23; Isaiah 3:24). Thus, the free growth of the hair on the head of the Nazarite represented the dedication of the man with all his strength and powers to the service of God.
Numbers 6:7
The consecration of his God - i. e. the unshorn locks: compare Leviticus 25:5 note, where the vine, left during the Sabbatical year untouched by the hand of man, either for pruning or for vintage, is called simply a "Nazarite."
The third rule of the Nazarite interdicted him from contracting any ceremonial defilement even under circumstances which excused such defilement in others: compare Leviticus 21:1-3.
Numbers 6:9-12
Prescriptions to meet the case of a sudden death taking place "by him" (i. e. in his presence). The days of the dedication of the Nazarite had to be recommenced.
Numbers 6:13
When the days of his separation are fulfilled - Perpetual Nazariteship was probably unknown in the days of Moses; but the examples of Samson, Samuel, and John the Baptist, show that it was in later times undertaken for life. Again, Moses does not expressly require that limits should be assigned to the vow; but a rule was afterward imposed that no Nazarite vow should be taken for less than thirty days. To permit the vow to be taken for very short periods would diminish its solemnity and estimation.
Numbers 6:14, Numbers 6:15
The sin-offering (compare the marginal references), though named second, was in practice offered first, being intended to expiate involuntary sins committed during the period of separation. The burnt-offering (Leviticus 1:10 ff) denoted the self-surrender on which alone all acceptableness in the Nazarite before God must rest; the peace-offerings (Leviticus 3:12 ff) expressed thankfulness to God by whose grace the vow had been fulfilled. The offerings, both ordinary and additional, required on the completion of the Nazarite vow involved considerable expense, and it was regarded as a pious work to provide the poor with the means of making them (compare Acts 21:23 ff; 1 Macc. 3:49).
Numbers 6:18
Shave the head - As the Nazarite had during his vow worn his hair unshorn in honor of God, so when the time was complete it was natural that the hair, the symbol of his vow, should be cut off, and offered to God at the sanctuary. The burning of the hair "in the fire under the sacrifice of the peace offering "represented the eucharistic communion with God obtained by those who realised the ideal which the Nazarite set forth (compare the marginal reference).
Numbers 6:20
The priest shall wave them - i. e. by placing his hands under those of the Nazarite: compare Leviticus 7:30.
Numbers 6:21
Beside that that his hand shall get - The Nazarite, in addition to the offerings prescribed above, was to present free-will offerings according to his possessions or means.
