²⁹ They must place their hand on the head of the animal for the sin offering. It must be killed at the place where the animals for burnt offerings are killed. ³⁰ Then the priest must dip his finger into some of the blood. He must put it on the horns that stick out from the upper four corners of the altar for burnt offerings. He must pour out the rest of the blood at the bottom of the altar. ³¹ They must remove all the fat in the same way the fat is removed from the friendship offering. The priest must burn it on the altar. Its smell pleases the Lord. When the priest burns the offering, he will pay for their sin. And they will be forgiven.
