Numbers 6:18

6:18 “‘Then the Nazirite must shave his consecrated head ¹  at the entrance to the tent of meeting and must take the hair from his consecrated head and put it on the fire ²  where the peace offering is burning. ³ 

Numbers 18:9

18:9 Of all the most holy offerings reserved ⁴  from the fire this will be yours: Every offering of theirs, whether from every grain offering or from every purification offering or from every reparation offering which they bring to me, will be most holy for you and for your sons.

[6:18]  ¹ tn Some versions simply interpret this to say that he shaves his hair, for it is the hair that is the sign of the consecration to God. But the text says he shaves his consecrated head. The whole person is obviously consecrated to God – not just the head. But the symbolic act of cutting the hair shows that the vow has been completed (see Acts 21:23-24). The understanding of the importance of the hair in the ancient world has been the subject of considerable study over the years (see R. de Vaux, Ancient Israel, 436; and J. A. Thompson, “Numbers,” New Bible Commentary: Revised, 177).

[6:18]  ² sn Some commentators see this burning of the hair as an offering (McNeile, Numbers, 35; G. B. Gray, Numbers [ICC], 68). But others probably with more foundation see it as destroying something that has served a purpose, something that if left alone might be venerated (see R. de Vaux, Israel, 436).

[6:18]  ³ tn Heb “which is under the peace offering.” The verse does not mean that the hair had to be put under that sacrifice and directly on the fire.

[18:9]  ⁴ tn Heb “from the fire.” It probably refers to those parts that were not burned.
