Leviticus 4:1-4

“The Lord said to Moses, ‘Say to the Israelites: “When anyone sins unintentionally and does what is forbidden in any of the Lord’s commands – if the anointed priest sins, bringing guilt on the people, he must bring to the Lord a young bull without defect as a sin offering for the sin he has committed. He is to present the bull at the entrance to the Tent of Meeting before the Lord. He is to lay his hand on its head and slaughter it before the Lord.” ‘ ”

Leviticus 5:1-6

“If a person sins because he does not speak up when he hears a public charge to testify regarding something he has seen or learned about, he will be held responsible. Or if a person touches anything ceremonially unclean – whether the carcasses of unclean wild animals or of unclean livestock or of unclean creatures that move along the ground – even though he is unaware of it, he has become unclean and is guilty. Or if he touches human uncleanness – anything that would make him unclean – even though he is unaware of it, when he learns of it he will be guilty. Or if a person thoughtlessly takes an oath to do anything, whether good or evil – in any matter one might carelessly swear about – even though he is unaware of it, in any case when he learns of it he will be guilty. When anyone is guilty in any way of these ways, he must confess in what way he has sinned and, as a penalty for the sin he has committed, he must bring to the Lord a fellowship offering; and the priest shall make atonement for him for his sin.”
