'Unknowingly' in the Bible

‘Also if one person sins unintentionally, then he shall offer a female goat one year old as a sin offering.

The priest shall make atonement before the Lord for the person who commits an error when he sins unintentionally, making atonement for him so that he may be forgiven.

You shall have one law for him who sins unintentionally, whether he is native-born among the Israelites or a stranger who is living among them as a resident alien.

So the Lord said to Aaron, “You and your sons and your father’s household (family) with you shall bear the guilt in connection with the sanctuary [that is, through your service as priests you will atone for the offenses which the people unknowingly commit when brought into contact with the manifestations of God’s presence]; and you and your sons with you shall bear the guilt in connection with your priesthood [that is, your own unintentional offenses].
