Leviticus 4:26-28

²⁶All its fat he shall burn on the altar, like the fat of the sacrifice of peace offerings; and the priest shall make atonement for him concerning his sin, and he will be forgiven.

²⁷“‘If anyone of the common people sins unwittingly, in doing any of the things which the LORD has commanded not to be done, and is guilty,

²⁸if his sin which he has sinned is made known to him, then he shall bring for his offering a goat, a female without defect, for his sin which he has sinned.
