Leviticus 4:26-30

²⁶And he shall burn all the fat at the altar, as the fat of the sanctified oblation (is burned); and the priest shall atone on his behalf for his sin, and it shall be forgiven him.

²⁷And if one of the people of the land inadvertently sin in doing contrary to any of the commandments of the Lord what is not right to do, and become guilty;

²⁸When his sin is known to him, in what he hath sinned, he shall bring his oblation, a female kid of the goats, unblemished, for the sin that he hath sinned.

²⁹And he shall lay his hand on the lead of the sin offering, and kill the sin offering at the place of burnt sacrifice;

³⁰And the priest shall take of the blood with his finger, and put it upon the horns of the altar of burnt offering, and pour out all the blood at the foundation of the altar.
