Numbers 15:30

But the soul that doeth [ought] presumptuously,.... Or with "an high hand" t, or through pride, as the Targum of Jonathan; in an haughty, insolent, bold and daring manner; in an obstinate, stubborn, self-willed way, with purpose and design, openly and publicly, neither fearing God nor regarding man:

[whether he be] born in the land, or a stranger; here a stranger as well signifies a proselyte of the gate as a proselyte of righteousness; seeing this presumptuous sinning may respect idolatry and blasphemy, which sins were punishable in proselytes of the gate by the magistrates of Israel as well as by the immediate hand of God:

the same reproacheth the Lord; by denying him to be the true Jehovah, by worshipping other gods, and by speaking in a blaspheming manner of him the true God; and indeed every presumptuous sin, which is committed in a bold and audacious manner, in contempt of God and defiance of his law, is a reproaching him the lawgiver, and a trampling upon his legislative power and authority:

and that soul shall be cut off from among his people, either by the hand of the civil magistrate, upon conviction of him, or by the immediate hand of God; no sacrifice was to be offered for such, no atonement to be made or forgiveness to be had; see Matthew 12:31.
