Leviticus 5:8-13

⁸And he shall bring them to the priest, and he shall offer the sin offering first, and wring off its head near to the spine, but he shall not divide (the bird).

⁹And he shall sprinkle the blood of the sin offering upon the side (wall) of the altar, and pour out the remainder of the blood at the base of the altar; it is a sin offering.

¹⁰And the second he shall make a burnt sacrifice, according to the proper (rite); and the priest shall make atonement for the sin that he hath sinned, and it shall be forgiven him.

¹¹But if (neither) two turtle doves nor a pair of young pigeons pertain to him, he shall bring, as his oblation for the sin that he hath sinned, the tenth of three sein of flour for a sin offering; he shall not put oil upon it, nor put frankincense upon it, for it is a sin offering.

¹²And he shall bring it to the priest, and the priest shall take a handful of it as the memorial thereof, and burn it at the altar with the oblations of the Lord: it is a sin offering.

¹³And the priest shall make atonement for him, for the sin that he hath sinned in anyone of these (things), and it shall be forgiven him: and to the priest it shall be, as the mincha.
