Num 6:9-11
But if any one died suddenly in a moment “by him” (עליו, in his neighbourhood), and he therefore involuntarily defiled his consecrated head, he was to shave his head on the day of his purification, i.e., on the seventh day (see Num 19:11, Num 19:14, Num 19:16, and Num 19:19), not “because such uncleanness was more especially caught and retained by the hair,” as Knobel fancies, but because it was the diadem of his God (Num 6:7), the ornament of his condition, which was sanctified to God. On the eighth day, that is to say, on the day after the legal purification, he was to bring to the priest at the tabernacle two turtle-doves or young pigeons, that he might make atonement for him (see at Lev 15:14-15, Lev 15:29., Num 14:30-31, and Num 12:8), on account of his having been defiled by a corpse, by preparing the one as a sin-offering, and the other as a burnt-offering; he was also “to sanctify his head that same day,” i.e., to consecrate it to God afresh, by the unimpeded growth of his hair.
