on't get the two mixed up.
Nu 15:27 And if any soul sin through ignorance, then he shall bring a she goat of the first year for a sin offering.
28 And the priest shall make an atonement for the soul that sinneth ignorantly, when he sinneth by ignorance before the LORD, to make an atonement for him; and it shall be forgiven him.
Nu 15:30 But the soul that doeth ought presumptuously, whether he be born in the land, or a stranger, the same reproacheth the LORD; and that soul shall be cut off from among his people.
31 Because he hath despised the word of the LORD, and hath broken his commandment, that soul shall utterly be cut off; his iniquity shall be upon him.
Just be glad we don't live under the "LAW".
These verses just prove my point! If someone sins in ignorance, why must there be a sin offering for that person since you said it's not really a sin uness one is conscience of their sin? These verses actually prove that conscience sin and unconscience sin both need atoning for!
