Matthew Poole and continuators on Numbers 6:7

7 He shall not make himself unclean for his father, or for his mother , for his brother, or for his sister, when they die: because the consecration of his God is upon his head.

Wherein he was equal to the High-priest, Lev. 21. 11. being, in some sort, as sacred a person, and as eminent a type of Christ, Heb. 7. 26. and therefore justly required to prefer the service of God to which he had so fully and peculiarly given himself before the expressions of his affections to his dearest and nearest relations.

(i. e.) The token of his consecration, to wit, his long hair.

(i. e.) Whereby he hath devoted himself to his God in an eminent manner. The Genitive case of the object.

Marginal references: Heb. separation.
