Leviticus 4:26-28

New Revised Standard Version Catholic Edition

²⁶ All its fat he shall turn into smoke on the altar, like the fat of the sacrifice of well-being. Thus the priest shall make atonement on his behalf for his sin, and he shall be forgiven.

²⁷ If anyone of the ordinary people among you sins unintentionally in doing any one of the things that by the Lord’s commandments ought not to be done and incurs guilt, ²⁸ when the sin that you have committed is made known to you, you shall bring a female goat without blemish as your offering, for the sin that you have committed.
