Leviticus 5:7-9

New Century Version

⁷ “‘But if the person cannot afford a lamb, he must bring two doves or two young pigeons to the Lord as the penalty for his sin. One bird must be for a sin offering, and the other must be for a whole burnt offering. ⁸ He must bring them to the priest, who will first offer the one for the sin offering. He will pull the bird’s head from its neck, but he will not pull it completely off. ⁹ He must sprinkle the blood from the sin offering on the side of the altar, and then he must pour the rest of the blood at the bottom of the altar; it is a sin offering.
