Leviticus 5:10-13

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.
