Numbers 6:9

“And if any man die very suddenly by him, etc.] In the place where he is, whether house or field, a public or private place, in the tent where he is, as Jarchi; there are two words we render, “very suddenly”, which many take to be synonymous; and that being of the same signification, two being used increase the sense, but others think they have a different meaning: the Targums of Onkelos and Jonathan render them, “suddenly through ignorance,” understanding it of a chance matter, as when one man is killed by another, not wilfully and through malice, but without intention and design: Jarchi interprets the first of them by violence, and the latter through error or mistake, and so may include…”

“If any man die very suddenly by him, and he hath defiled the head of his consecration--Cases of sudden death might occur to make him contract pollution; and in such circumstances he was required, after shaving his head, to make the prescribed offerings necessary for the removal of ceremonial defilement (Lev 15:13; Num 19:11). But by the terms of this law an accidental defilement vitiated the whole of his previous observances, and he was required to begin the period of his Nazaritism afresh. But even this full completion did not supersede the necessity of a sin offering at the close. Sin mingles with our best and holiest performances, and the blood of sprinkling is necessary to procure…”

“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…”

“He shall shave his head - Because his whole body, and especially his hair was defiled by such an accident, which he ought to impute either to his own heedlessness, or to God's providence so ordering the matter, possibly for the punishment of his other sins, or for the quickening him to more purity and detestation of all dead works, whereby he would be defiled. Numbers 6:11”

“6:9-21 Provisions were made for restoring purity in cases of unavoidable contact with a corpse. Special procedures and offerings brought the period of the Nazirite vow to a conclusion. A stern warning is added about actually fulfilling the vow (6:21).”

“and he: Num 19:14-19 shave: Num 6:18; Act 18:18, Act 21:23, Act 21:24; Phi 3:8, Phi 3:9 Numbers 6:10”
