Shall offer, Heb. make, which is oft put for sacrificing or offering, as Exo_29:361Ch_21:23, compared with 2Sa_24:22.
For a sin-offering, 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. For that he sinned, 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.
Shall hallow; begin again to hallow or consecrate it.
