Leviticus 4:29-32

²⁹He must lay his hands on the goat's head and slaughter it at the place where they slaughter the animals that will be completely burned on the altar, and catch some of the blood in a bowl.

³⁰Then the priest must dip one of his fingers in it, and put some of the blood on the projections at the corners of the altar. Then he must pour out the rest of the blood at the base of the altar.

³¹Then he must remove all the goat's fat, and burn all the fat on the altar, like was done with the fat of the offering to maintain fellowship with Yahweh. And the aroma while it burns will be pleasing to Yahweh. As a result of the priest doing that, the person will no longer be guilty for his sin, and he will be forgiven.

³²If that person brings a lamb to be his offering for sin, he must bring a female lamb that has no defects.
