Numbers 6:18

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

Numbers 8:7

8:7 And do this to them to purify them: Sprinkle water of purification on them; then have them shave all their body and wash their clothes, and so purify themselves.

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).

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).

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.

tn Or, more literally, “and thus you shall do.” The verb is the imperfect tense of instruction or legislation. Here it introduces the procedures to be followed.

tn The genitive in this expression indicates the purpose of the water – it is for their purification. The expression is literally “the waters of sin.” The word “purification” is the same as for the “sin/purification offering” – חַטָּאת (khattaat). This water seems to have been taken from the main laver and is contrasted with the complete washing of the priests in Lev 8:6.

tn The verb is the Hiphil perfect with a vav (ו) of sequence. This verb, and those to follow, has the force of a jussive since it comes after the imperative. Here the instruction is for them to remove the hair from their bodies (“flesh”). There is no indication that this was repeated (as the Egyptian priests did every few days). It seems to have been for this special occasion only. A similar requirement was for the leper (Lev 14:7-9).

tn Heb “flesh.”

tn Or “let/have them wash”; the priests were given new clothes (Lev 8:13), but the Levites simply washed their own.

tn The verb is a reflexive (or possibly passive) in this verse, indicating the summary of the process. The ritual steps that have been prescribed will lead to this conclusion. The verb could be treated as a final imperfect (being a perfect with vav [ו] consecutive), and so translated “that they may….” The major difference here is that the ritual made the Levites “clean,” whereas the ritual for the priests made them “holy” or “sanctified” (Lev 8:12).
