Numbers 6:11
And the priest shall offer the one for a sin offering, and the other for a burnt offering, and make an atonement for him, for that he sinned by the dead, and shall hallow his head that same day.
And the priest shall offer the one for a sin offering, and the other for a burnt offering,.... That is, one of the turtles or young pigeons for the one kind of sacrifice, and one for the other sort; both being necessary; the one to expiate sin, and the other as a gift to God by way of thankfulness for acceptance of the former:
and make an atonement for him, for that he sinned by the dead; by being where the dead body was, which, though not sinful, in a moral sense, was, in a ceremonial one, and therefore required a sacrifice to atone for it; and which atonement was made by the sin offering typical of Christ, who was made an offering for sin:
and shall hallow his head the same day; consecrate himself to God afresh, particularly the hair of his head, let that grow again and begin his Nazariteship anew; so Jarchi interprets it, to return and begin the account of his Nazariteship.
