Matthew Poole and continuators on Numbers 6:11

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 sameday.

Heb. make: which is oft put for sacrificing or offering, as Exod. 29. 36. 1 Chron. 21. 23. compared with 2 Sam. 24. 22.

Because such a pollution was though not his sin, yet the chastisement of his sin, and had an appearance of sin, to wit, of negligence in not standing sufficiently upon his guard, which in such persons was in a manner equivalent to a sin.

(i. e.) Contracted a ceremonial uncleanness, which is called sinning, because it was a type of sin, and a violation of a law, though through ignorance and inadvertency, as many other sins were.

Begin again to hallow or consecrate it.
