'Unintentionally' 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.

then you shall select for yourselves cities to be cities of refuge, so that the one who kills any person unintentionally may escape there.

These six cities shall be a refuge for the Israelites and for the stranger and the resident alien among them; so that anyone who kills a person unintentionally may escape there.
